[Footnote 1: Of the Emys trijuga, the fresh water tortoise figured on preceding page, the technical characteristics are;—vertical plates lozenge-shaped; shell convex and oval; with three more or less distinct longitudinal keels; shields corrugated; with areola situated in the upper posterior corner. Shell brown, with the areolae and the keels yellowish; head brown, with a yellow streak over each eye.]
The edible turtle[1] is found on all the coasts of the island, and sells for a few shillings or a few pence, according to its size and abundance at the moment. A very repulsive spectacle is exhibited in the markets of Jaffna by the mode in which the flesh of the turtle is sold piece-meal, whilst the animal is still alive, by the families of the Tamil fishermen. The creatures are to be seen in the market-place undergoing this frightful mutilation; the plastron and its integuments having been previously removed, and the animal thrown on its back, so as to display all the motions of the heart, viscera, and lungs. A broad knife, from twelve to eighteen inches in length, is first inserted at the left side, and the women, who are generally the operators, introduce one hand to scoop out the blood, which oozes slowly. The blade is next passed round, till the lower shell is detached and placed on one side, and the internal organs exposed in full action. A customer, as he applies, is served with any part selected, which is cut off as ordered, and sold by weight. Each of the fins is thus successively removed, with portions of the fat and flesh, the turtle showing, by its contortions, that each act of severance is productive of agony. In this state it lies for hours, writhing in the sun, the heart[2] and head being usually the last pieces selected, and till the latter is cut off the snapping of the mouth, and the opening and closing of the eyes, show that life is still inherent, even when the shell has been nearly divested of its contents.
[Footnote 1: Chelonia virgata, Schweig.]
[Footnote 2: ARISTOTLE was aware of the fact that the turtle will live after the removal of the heart.—De Vita et Morte, ch. ii.]
At certain seasons the flesh of turtle on the south-western coast of Ceylon is avoided as poisonous, and some lamentable instances are recorded of deaths ascribed to its use. At Pantura, to the south of Colombo, twenty-eight persons who had partaken of turtle in October, 1840, were immediately seized with sickness, after which coma supervened, and eighteen died during the night. Those who survived said there was nothing unusual in the appearance of the flesh except that it was fatter than ordinary. Other similarly fatal occurrences have been attributed to turtle curry; but as they have never been proved to proceed exclusively from that source, there is room for believing that the poison may have been contained in some other ingredient.
In the Gulf of Manaar turtle is frequently found of such a size as to measure between four and five feet in length; and on one occasion, in riding along the sea-shore north of Putlam, I saw a man in charge of some sheep, resting under the shade of a turtle shell, which he had erected on sticks to protect him from the sun—almost verifying the statement of AElian, that in the seas off Ceylon there are tortoises so large that several persons may find ample shelter beneath a single shell.[1]
[Footnote 1: [Greek: "Tiktontai de ara en taute te thalatte, kai chelonai megistai, onper oun ta elytra orophoi ginontai kai gar esti kai pentekaideka pechon en cheloneion, os hypoikein ouk oligous, kai tous helious pyrodestatous apostegei, kai skian asmenois parechei."]—Lib. xvi. c. 17. AElian copied this statement literatim from MEGASTHESES, Indica Frag. lix. 31. May not Megasthenes have referred to some tradition connected with the gigantic fossilised species discovered on the Sewalik Hills, the remains of which are now in the Museum at the East India House?]
The hawksbill-turtle[1], which supplies the tortoise-shell of commerce, was at former times taken in great numbers in the vicinity of Hambangtotte during the season when they came to deposit their eggs. This gave rise to the trade in tortoise-shell at Point de Galle, where it is still manufactured into articles of ornament by the Moors; but the shell they employ is almost entirely imported from the Maldives.
[Footnote 1: Caretta imbricata, Linn.]
If taken from the animal after death and decomposition, the colour of the shell becomes clouded and milky, and hence the cruel expedient is resorted to of seizing the turtles as they repair to the shore to deposit their eggs, and suspending them over fires till heat makes the plates on the dorsal shields start from the bone of the carapace, after which the creature is permitted to escape to the water.[1] In illustration of the resistless influence of instinct at the period of breeding, it may be mentioned that the identical tortoise is believed to return again and again to the same spot, notwithstanding that at each visit she may have to undergo a repetition of this torture. In the year 1826, a hawksbill turtle was taken near Hambangtotte, which bore a ring attached to one of its fins that had been placed there by a Dutch officer thirty years before, with a view to establish the fact of these recurring visits to the same beach.[2]
[Footnote 1: At Celebes, whence the finest tortoise-shell is exported to China, the natives kill the turtle by blows on the head, and immerse the shell in boiling water to detach the plates. Dry heat is only resorted to by the unskilful, who frequently destroy the tortoise-shell in the operation—Journal Indian Archipel. vol. iii. p. 227, 1849.]
[Footnote 2: BENNETT'S Ceylon, &c., c. xxxiv.]
An opportunity is afforded on the sea-shore of Ceylon for observing a remarkable illustration of instinct in the turtle, when about to deposit its eggs. As if conscious that if she went and returned by one and the same line across the sandy beach, her hiding place would be discovered at its farthest extremity, she resorts to the expedient of curving her course, so as to regain the sea by a different track; and after depositing the eggs, burying them about eighteen inches deep, she carefully smoothes over the surface to render the precise spot indiscernible. The Singhalese, aware of this device, sound her line of, march with a rod till they come upon the concealed nest.
Snakes.—It is perhaps owing to the aversion excited by the ferocious expression and unusual action of serpents, combined with an instinctive dread of attack[1], that exaggerated ideas prevail both as to their numbers in Ceylon, and the danger to be apprehended from encountering them. The Singhalese profess to distinguish a great many kinds, of which they say not more than one half have as yet been scientifically identified[2]; but so cautiously do serpents make their appearance, that the surprise of persons long resident is invariably expressed at the rarity with which they are to be seen; and from my own journeys through the jungle, often of from two to five hundred miles, I have frequently returned without observing a single snake. Mr. Bennett, who resided much in the south-east of the island, ascribes the rarity of serpents in the jungle to the abundance of the wild peafowl, whose partiality to young snakes renders them the chief destroyers of these reptiles. It is likely, too, that they are killed by the jungle-cocks; for they are frequently eaten by the common barn-door fowl in Ceylon. This is rendered the more probable by the fact, that in those districts where the extension of cultivation, and the visits of sportsmen, have reduced the numbers of the jungle-cocks and pea-fowl, snakes have perceptibly increased. The deer also are enemies of the snakes, and the natives who have had opportunities of watching their encounters assert that they have seen deer rush upon a serpent and crush it by leaping on it with all its four feet. As to the venomous powers of snakes, DR. DAVY, whose attention was carefully directed to the poisonous serpents of Ceylon[3], came to the conclusion that but four, out of twenty species examined by him, were venomous, and that of these only two (the tic-polonga[4] and cobra de capello[5]) were capable of inflicting a wound likely to be fatal to man. The third is the carawala[6], a brown snake of about two feet in length; and for the fourth, of which only a few specimens have been procured, the Singhalese have no name in their vernacular—a proof that it is neither deadly nor abundant. But Dr. Davy's estimate of the venom of the carawala is below the truth, as cases have been authenticated to me, in which death from its bite ensued within a few days. The effect, however, is not uniformly fatal; a circumstance which the natives explain by asserting that there are three varieties of the carawala, named the hil-la, the dunu, and the mal-carawala; the second being the largest and the most dreaded.
[Footnote 1: Genesis iii. 15.]
[Footnote 2: This is not likely to be true: in a very large collection of snakes made in Ceylon by Mr. C.R. Butler, and recently examined by Dr. Guenther, of the British Museum, only a single-specimen proved to be new.
There is, however, one venomous snake, of the existence of which I am assured by a native correspondent in Ceylon, no mention has yet been made by European naturalists. It is called Māpilā by the Singhalese; it is described to me as being about four feet in length, of the diameter of the little finger, and of a uniform dark brown colour. It is said to be often seen in company with another snake called in Singhalese Lay Medilla, a name which implies its deep red hue. The latter is believed to be venomous. It would be well if some collector in Ceylon would send home for examination the species which respectively bear these names.]
[Footnote 3: See DAVY'S Ceylon, ch. xiv.]
[Footnote 4: Daboia elegans, Daud.]
[Footnote 5: Naja tripudians, Merr.]
[Footnote 6: Trigonocephalus hypnale, Merr.]
In like manner, the tic-polonga, particularised by Dr. Davy, is said to be but one out of seven varieties of that formidable reptile. The word "tic" means literally the "spotted" polonga, from the superior clearness of the markings on its scales. Another, the nidi, or "sleeping" polonga, is so called from the fact that a person bitten by it is soon prostrated by a lethargy from which he never awakes.[1] These formidable serpents so infested the official residence of the District Judge of Trincomalie in 1858, as to compel his family to abandon it. In another instance, a friend of mine, going hastily to take a supply of wafers from an open tin case which stood in his office, drew back his hand, on finding the box occupied by a tic-polonga coiled within it. During my residence in Ceylon, I never heard of the death of a European which was caused by the bite of a snake; and in the returns of coroners' inquests made officially to my department, such accidents to the natives appear chiefly to have happened at night, when the animal, having been surprised or trodden on, inflicted the wound in self-defence.[2] For these reasons the Singhalese, when obliged to leave their houses in the dark, carry a stick with a loose ring, the noise[3] of which as they strike it on the ground is sufficient to warn the snakes to leave their path.
[Footnote 1: The other varieties are the getta, lay, alu, kunu, and nil-polongas. I have heard of an eighth, the palla-polonga.
Amongst the numerous pieces of folk-lore in Ceylon in connexion with snakes, is the belief that a deadly enmity subsists between the polonga and the cobra de capello, and that the latter, which is naturally shy and retiring, is provoked to conflicts by the audacity of its rival. Hence the proverb applied to persons at enmity, that "they hate like the polonga and cobra."
The Singhalese believe the polonga to be by far the most savage and wanton of the two, and they illustrate this by a popular legend, that once upon a time a child, in the absence of its mother, was playing beside a tub of water, which a cobra, impelled by thirst during a long-continued drought, approached to drink, the unconscious child all the while striking it with its hands to prevent the intrusion. The cobra, on returning, was met by a tic-polonga, which seeing its scales dripping with delicious moisture, entreated to be told the way to the well. The cobra, knowing the vicious habits of the other snake, and anticipating that it would kill the innocent child which it had so recently spared, at first refused, and only yielded on condition that the infant was not to be molested. But the polonga, on reaching the tub, was no sooner obstructed by the little one, than it stung him to death.]
[Footnote 2: In a return of 112 coroners' inquests, in cases of death from wild animals, held in Ceylon in five years, from 1851 to 1855 inclusive, 68 are ascribed to the bites of serpents; and in almost every instance the assault is set down as having taken place at night. The majority of the sufferers were children and women.]
[Footnote 3: PLINY notices that the serpent has the sense of hearing more acute than that of sight; and that it is more frequently put in motion by the sound of footsteps than by the appearance of the intruder, "excitatur pede saepius."—Lib, viii. c. 36.]
Cobra de Capello.—The cobra de capello is the only one exhibited by the itinerant snake-charmers: and the truth of Davy's conjecture, that they control it, not by extracting its fangs, but by courageously availing themselves of its well-known timidity and extreme reluctance to use its fatal weapons, received a painful confirmation during my residence in Ceylon, by the death of one of these performers, whom his audience had provoked to attempt some unaccustomed familiarity with the cobra; it bit him on the wrist, and he expired the same evening. The hill near Kandy, on which the official residences of the Governor and Colonial Secretary are built, is covered in many places with the deserted nests of the white ants (termites), and these are the favourite retreats of the sluggish and spiritless cobra, which watches from their apertures the toads and lizards on which it preys. Here, when I have repeatedly come upon them, their only impulse was concealment; and on one occasion, when a cobra of considerable length could not escape, owing to the bank being nearly precipitous on both sides of the road, a few blows from my whip were sufficient to deprive it of life.[1]
[Footnote 1: A Singhalese work, the Sarpadosā, enumerates four castes of the cobra;—the raja, or king: the bamunu, or Brahman; the velanda, or trader; and the gori, or agriculturist. Of these the raja, or "king of the cobras," is said to have the head and the anterior half of the body of so light a colour, that at a distance it seems like a silvery white. The work is quoted, but not correctly, in the Ceylon Times for January, 1857. It is more than probable, as the division represents the four castes of the Hindus, Chastriyas, Brahmans Vaisyas, and Sudras; that the insertion of the gori instead of the latter was a pious fraud of some copyist to confer rank upon the Vellales, the agricultural caste of Ceylon.]
A gentleman who held a civil appointment at Kornegalle, had a servant who was bitten by a snake and he informed me that on enlarging a hole near the foot of the tree under which the accident occurred, he unearthed a cobra of upwards of three feet long, and so purely white as to induce him to believe that it was an albino. With the exception of the rat-snake[1], the cobra de capello is the only serpent which seems from choice to frequent the vicinity of human dwellings, doubtless attracted by the young of the domestic fowl and by the moisture of the wells and drainage.
[Footnote 1: Coryphodon Blumenbachii. There is a belief in Ceylon that the bite of the rat-snake, though harmless to man, is fatal to black cattle. The Singhalese add that it would be equally so to man were the wound to be touched by cow-dung. WOLF, in the interesting story of his Life and Adventures in Ceylon, mentions that rat-snakes were often so domesticated by the native as to feed at their table. He says: "I once saw an example of this in the house of a native. It being meal time, he called his snake, which immediately came forth from the roof under which he and I were sitting. He gave it victuals from his own dish, which the snake took of itself from off a fig-leaf that was laid for it, and ate along with its host. When it had eaten its fill, he gave it a kiss, and bade it go to its hole." Major SKINNER, writing to me 12th Dec., 1858, mentions the still more remarkable case of the domestication of the cobra de capello in Ceylon. "Did you ever hear," he says, "of tame cobras being kept and domesticated about a house, going in and out at pleasure, and in common with the rest of the inmates? In one family, near Negombo, cobras are kept as protectors, in the place of dogs, by a wealthy man who has always large sums of money in his house. But this is not a solitary case of the kind. I heard of it only the other day, but from undoubtedly good authority. The snakes glide about the house, a terror to thieves, but never attempting to harm the inmates."]
The young cobras, it is said, in the Sarpa-dosa, are not venomous till after the thirteenth day, when they shed their coat for the first time.
The Singhalese remark that if one cobra be destroyed near a house, its companion is almost certain to be discovered immediately after,—a popular belief which I had an opportunity of verifying on more than one occasion. Once, when a snake of this description was killed in a bath of the Government House at Colombo, its mate was found in the same spot the day after; and again, at my own stables, a cobra of five feet long, having fallen into the well, which was too deep to permit its escape, its companion of the same size was found the same morning in an adjoining drain.[1] On this occasion the snake, which had been several hours in the well, swam with ease, raising its head and hood above water; and instances have repeatedly occurred of the cobra de capello voluntarily taking considerable excursions by sea. When the "Wellington," a government vessel employed in the conservancy of the pearl banks, was anchored about a quarter of a mile from the land, in the bay of Koodremale, a cobra was seen, about an hour before sunset, swimming vigorously towards the ship. It came within twelve yards, when the sailors assailed it with billets of wood and other missiles, and forced it to return to land. The following morning they discovered the track which it had left on the shore, and traced it along the sand till it was lost in the jungle. On a later occasion, in the vicinity of the same spot, when the "Wellington" was lying at some distance from the shore, a cobra was found and killed on board, where it could only have gained access by climbing up the cable. It was first discovered by a sailor, who felt the chill as it glided over his foot.
[Footnote 1: PLINY notices the affection that subsists between the male and female asp; and that if one of them happens to be killed, the other seeks to avenge its death.—Lib. viii. c. 37.]
One curious tradition in Ceylon embodies the popular legend, that the stomach of the cobra de capello occasionally contains a precious stone of such unapproachable brilliancy as to surpass all known jewels. This inestimable stone is called the nāga-mānik-kya; but not one snake in thousands is supposed to possess such a treasure. The cobra, before eating, is believed to cast it up and conceal it for the moment; else its splendour, like a flambeau, would attract all beholders. The tales of the peasantry, in relation to it, all turn upon the devices of those in search of the gem, and the vigilance and cunning of the cobra by which they are baffled; the reptile itself being more enamoured of the priceless jewel than even its most ardent pursuers.
In BENNETT'S account of "Ceylon and its Capabilities," there is another curious piece of Singhalese folk-lore, to the effect, that the cobra de capello every time it expends its poison loses a joint of its tail, and eventually acquires a head resembling that of a toad. A recent addition to zoological knowledge has thrown light on the origin of this popular fallacy. The family of "false snakes" (pseudo typhlops, as Schlegel names the group) have till lately consisted of but three species, of which only one was known to inhabit Ceylon. They belong to a family intermediate between the serpents and that Saurian group-commonly called Slow-worms or Glass-snakes; they in fact represent the slow-worms of the temperate regions in Ceylon. They have the body of a snake, but the cleft of their mouth is very narrow, and they are unable to detach the lateral parts of the lower jaw from each other, as the true snakes do when devouring a prey. The most striking character of the group, however, is the size and form of the tail; this is very short, and according to the observations of Professor Peters of Berlin[1], shorter in the female than in the male. It does not terminate in a point as in other snakes, but is truncated obliquely, the abrupt surface of its extremity being either entirely flat, or more or less convex, and always covered with rough keels. The reptile assists its own movements by pressing the rough end to the ground, and from this peculiar form of the tail, the family has received the name of Uropeltidae, or "Shield-tails." Within a very recent period important additions have been made to this family. which now consists of four genera and eleven species. Those occurring in Ceylon are enumerated in the List appended to this chapter. One of these, the Uropeltis grandis of Kelaart[2], is distinguished by its dark brown colour, shot with a bluish metallic lustre, closely approaching the ordinary shade of the cobra; and the tail is abruptly and flatly compressed as though it had been severed by a knife. The form of this singular reptile will be best understood by a reference to the accompanying figure; and there can, I think, be little doubt that to its strange and anomalous structure is to be traced the fable of the transformation of the cobra de capello. The colour alone would seem to identify the two reptiles, but the head and mouth are no longer those of a serpent, and the disappearance of the tail might readily suggest the mutilation which the tradition asserts.
[Footnote 1: PETERS, De Serpentum familia Uropeltaceorum. Berol, 4. 1861.]
[Footnote 2: The Uropeltis grandis of Kelaart, which was at first supposed to be a new species, proves to be identical with U. Phillippinus of Cuvier. It is doubtful, however, whether this species be found in the Phillippine Islands, as stated by Cuvier; and it is more than, probable that the typical specimen came from Ceylon—a further illustration of the affinity of the fauna of Ceylon to that of the Eastern Archipelago. The characteristics of this reptile, as given by Dr. GRAY, are as follows:—"Caudal disc subcircular, with large scattered tubercles; snout subacute, slightly produced. Dark brown, lighter below, with some of the scales dark brown in the centre near the posterior edge. GRAY, Proceed. Zool. Soc. 1858, p. 262.]
The Singhalese Buddhists, in their religious abstinence from inflicting death on any creature, are accustomed, after securing a venomous snake, to enclose it in a basket woven of palm leaves, and to set it afloat on a river.
The Python.—The great python[1] (the "boa," as it is commonly designated by Europeans, the "anaconda" of Eastern story), which is supposed to crush the bones of an elephant, and to swallow the tiger, is found, though not of such portentous dimensions, in the cinnamon gardens within a mile of the fort of Colombo, where it feeds on hog-deer, and other smaller animals.
[Footnote 1: Python reticulatus, Gray.]
The natives occasionally take it alive, and securing it to a pole expose it for sale as a curiosity. One that was brought to me tied in this way measured seventeen feet with a proportionate thickness: but one more fully grown, which crossed my path on a coffee estate on the Peacock Mountain at Pusilawa, considerably exceeded these dimensions. Another which I watched in the garden at Elie House, near Colombo, surprised me by the ease with which it erected itself almost perpendicularly in order to scale a wall upwards of ten feet high.
The Singhalese assert that when it has swallowed a deer, or any animal of similarly inconvenient bulk, the python draws itself through the narrow aperture between two trees, in order to crush the bones and assist in the process of deglutition.
It is a singular fact that the small and innocuous ground-snakes called Calamariae, which abound on the continent of India and in the islands are not to be found in Ceylon; where they would appear to be replaced by two singular genera, the Aspidura and Haplocercus, These latter have only one series of shields below the tail, whilst most other harmless snakes (Calamaria included) have a double series of sub-candals. The Aspidura has been known to naturalists for many years[1]; the Haplocercus of Ceylon has only recently been described by Dr. Guenther, and of it not more than three existing specimens are known: hence its habits and the extent of its distribution over the island are still left in uncertainty.[2]
[Footnote 1: Boie in Isis 1827 p. 517.]
[Footnote 2: GUeNTH. Col. Snakes, p. 14. In the hope that some inquirer in Ceylon will be able to furnish such information as may fill up this blank in the history of the haplocercus, the following particulars are here appended. The largest of the specimens in the British Museum is about twenty-five inches in length; the body thin, and much elongated; the head narrow, and not distinct from the neck, the tail of moderate length. Forehead covered by three shields, one anterior and two posterior frontals; no loreal shield; one small shield before, two behind the eye; seven shields along the upper lip, the eye being above the fourth. The scales are disposed in seventeen longitudinal series; they are lanceolate and strongly keeled. The upper parts are uniform blackish or brown, with two dorsal rows of small indistinct black spots; occiput with a whitish collar, edged with darker. The lower parts uniform yellowish.]
Of ten species of snakes that ascend trees in Ceylon to search for squirrels and lizards, and to rifle the nests of birds, one half, including the green carawala, and the deadly tic polonga, are believed by the natives to be venomous; but the truth of this is very dubious. I have heard of the cobra being found on the crown of a coco-nut palm, attracted, it was said, by the toddy which was flowing at the time, it being the season for drawing it. Surrounding Elie House, near Colombo, in which I resided, were a number of tall casuarinas and India-rubber trees, whose branches almost touched the lattices of the window of the room in which I usually sat. These were a favourite resort of the tree-snakes, and in the early morning the numbers which clung to them were sometimes quite remarkable. I had thus an opportunity of observing the action of these creatures, which seems to me one of vigilance rather than of effort, the tongue being in perpetual activity, as if it were an organ of feeling; and in those in which the nose is elongated, a similar mobility and restlessness, especially when alarmed, affords evidence of the same faculty.
The general characteristic of the Tree-snake is an exceedingly thin and delicate body, often adorned with colours exquisite as those of the foliage amongst which they live concealed. In some of the South American species the tints vie in brilliancy with those of the humming-birds; whilst their forms are so flexible and slender as to justify the name conferred on them of "whip-snakes." The Siamese, to denote these combinations of grace and splendour, call them "Sun-beams." A naturalist[1], describing a bright green species in Brazil (Philodryas viridissimus), writes: "I am always delighted when I find that another tree-snake has settled in my garden. You look for a bird's nest, the young ones have gone, but you find their bed occupied by one of these beautiful creatures, which will coil up its body of two feet in length within a space no larger than the hollow of your hand. They appear to be always watchful; for at the instant you discover one, the quick playing of the long, black, forked tongue will show you that you too are observed. On perceiving the slightest sign of your intention to disturb it, the snake will dart upwards through the branches and over the leaves which scarcely appear to bend beneath the weight. A moment more, and you have lost sight of it. Whenever I return to Europe, you may be sure that in my hot-house those harmless, lovely creatures shall not be missing."
[Footnote 1: Dr. WUCHERER of Bahia.]
Ceylon has several species of Tree-snakes, and one of the most common is the green Passerita, easily recognized from its bright colour and from the pointed moveable appendage, into which the snout is prolonged. The snakes of this genus being active chiefly during the night, the pupil of the eye is linear and horizontal. They never willingly descend from trees, but prey there upon nocturnal Saurians, geckoes, small birds and their young; and they are perfectly harmless, although they often try to bite. It is strange that none of the numerous specimens which it has been attempted to bring to Europe have ever fed in captivity; whilst in South America they take their food freely in confinement, provided that some green plants are placed in their cage.
In Ceylon I have never seen any specimen of a larger size than three feet; whilst they are known to attain to more than five on the Indian Continent.
The inference is obvious, that the green coloration of the majority of tree-snakes has more or less connection with their habits and mode of life. Indeed, whenever a green-coloured snake is observed, it may at once be pronounced, if slender or provided with a prehensile tail, to be of the kind which passes its life on trees; but if it be short-bodied then it lives on the prairies. There are nevertheless tree-snakes which have a very different coloration; and one of the most remarkable species is the Passerita fusca or Dryinus fuscus, of which a figure is annexed. It closely resembles the green Passerita in form, so that naturalists have considered it to be a mere variety. It is entirely of a shining brown, shot with purple, and the yellow longitudinal stripe which runs along the side of the belly of the green species, is absent in this one. It is much more rare than the green one, and does not appear to be found in Hindostan: no intermediate forms have been observed in Ceylon.
Water-Snakes.—The fresh-water snakes, of which several species[1] inhabit the still waters and pools, are all harmless in Ceylon. A gentleman, who found near a river an agglutinated cluster of the eggs of one variety (Tropidophis schistosus), placed them under a glass shade on his drawing-room table, where one by one the young reptiles emerged from the shell to the number of twenty.
[Footnote 1: Chersydrus granulatus, Merr.; Cerberus cinereus. Daud.; Tropidophis schistosus, Daud.]
The sea-snakes of the Indian tropics did not escape the notice of the early Greek mariners who navigated those seas; and amongst the facts collected by them, AElian has briefly recorded that the Indian Ocean produces serpents with flattened tails[1], whose bite, he adds, is to be dreaded less for its venom than the laceration of its teeth. The first statement is accurate, but the latter is incorrect, as there is an all but unanimous concurrence of opinion that every species of this family of serpents is more or less poisonous. The compression of the tail noticed by AElian is one of the principal characteristics of these reptiles, as their motion through the water is mainly effected by its aid, coupled with the undulating movement of the rest of the body. Their scales, instead of being imbricated like those of land-snakes, form hexagons; and those on the belly, instead of being scutate and enlarged, are nearly of the same size and form as on other parts of the body.
[Footnote 1: "[Greek: Plateis tas ouras]." AELIAN, L. xvi. c. 8.
AElian speaks elsewhere of fresh-water snakes. His remark on the compression of the tail shows that his informants were aware of this speciality in those that inhabit the sea.]
Sea-snakes (Hydrophis) are found on all the coasts of Ceylon. I have sailed through large shoals of them in the Gulf of Manaar, close to the pearl-banks of Aripo. The fishermen of Calpentyn on the west live in perpetual dread of them, and believe their bite to be fatal. In the course of an attempt which was recently made to place a lighthouse on the great rocks of the south-east coast, known by seamen as the Basses[1], or Baxos, the workmen who first landed found the portion of the surface liable to be covered by the tides, honeycombed, and hollowed into deep holes filled with water, in which were abundance of fishes and some molluscs. Some of these cavities also contained sea-snakes from four to five feet long, which were described as having the head "hooded like the cobra de capello, and of a light grey colour, slightly speckled. They coiled themselves like serpents on land, and darted at poles thrust in among them. The Singhalese who accompanied the party, said that they not only bit venomously, but crushed the limb of any intruder in their coils."[2]
[Footnote 1: The Basses are believed to be the remnants of the great island of Giri, swallowed up by the sea.—Mahawanso, ch. i. p. 4. They may possibly be the Bassae of Ptolemy's map of Taprobane.]
[Footnote 2: Official Report to the Governor of Ceylon.]
Still, sea-snakes, though well-known to the natives, are not abundant round Ceylon, as compared with their numbers in other places. Their principal habitat is the ocean between the southern shores of China and the northern coast of New Holland; and their western limit appears to be about the longitude of Cape Comorin. It has long since been ascertained that they frequent the seas that separate the islands of the Pacific; but they have never yet been found in the Atlantic, nor even on the western shores of tropical America. And if, as has been stated[1], they have been seen on a late occasion in considerable numbers in the Bay of Panama, the fact can only be regarded as one of the rare instances, in which a change in the primary distribution of a race of animals has occurred, either by an active or a passive immigration. Being exclusively inhabitants of the sea, they are liable to be swept along by the influence of currents; but to compensate for this they have been endowed with a wonderful power of swimming. The individuals of all the groups of terrestrial serpents are observed to be possessed of this faculty to a greater or a less degree; and they can swim for a certain distance without having any organs specially modified for the purpose; except, perhaps, the lung, which is a long sac capable of taking in a sufficient quantity of air, to keep the body of the snake above water. Nor do we find any peculiar or specially adapted organs even in the freshwater-snakes, although they can catch frogs or fishes while swimming. But in the hydrophids, which are permanent inhabitants of the ocean, and which in an adult state, approach the beach only occasionally, and for very short times, the tail, which is rounded and tapering in the others, is compressed into a vertical rudder-like organ, similar to, and answering all the purposes of, the caudal fin in a fish. When these snakes are brought on shore or on the deck of a ship, they are helpless and struggle vainly in awkward attitudes. Their food consists exclusively of such fishes as are found near the surface; a fact which affords ample proof that they do not descend to great depths, although they can dive as well as swim. They are often found in groups during calm weather, sleeping on the sea; but owing to their extreme caution and shyness, attempts to catch them are rarely successful; on the least alarm, they suddenly expel the air from their lungs and descend below the surface; a long stream of rising air-bubbles marking the rapid course which they make below. Their poisonous nature has been questioned; but the presence of a strong perforated tooth and of a venomous gland sufficiently attest their dangerous powers, even if these had not been demonstrated by the effects of their bite. But fortunately for the fishermen, who sometimes find them unexpectedly among the contents of their nets, sea-snakes are unable, like other venomous serpents, to open the jaws widely, and in reality they rarely inflict a wound. Dr. Cantor believes, that, they are blinded by the light when removed from their own element; and he adds that they become sluggish and speedily die.[2]

Those found near the coasts of Ceylon are generally small,—from one to three feet in length, and apparently immature; and it is certain that the largest specimens taken in the Pacific do not attain to greater length than eight feet. In colour they are generally of a greenish brown, in parts inclining to yellow, with occasionally cross bands of black. The species figured in the accompanying drawing is the Hydrophis subloevis of Gray; or Hydrus cyanocinctus of Boie.[1] The specimen from which the drawing is taken, was obtained by Dr. Templeton at Colombo.
[Footnote 1: Its technical characteristics are as follows,—Body rather slender; ground colour yellowish with irregular black rings. Scales nearly smooth; ventral plates broad, six-sided, smooth, some divided into two, by a slight central groove. Occipital shields large, triangular, and produced, with a small central shield behind them; a series of four large temporal shields; chin shields in two pairs; eyes very small, over the fourth and fifth labials; one ante-and two post-oculars; the second upper labial shield elongated.]
The use of the Pamboo-Kaloo, or snake-stone, as a remedy in cases of wounds by venomous serpents, has probably been communicated to the Singhalese by the itinerant snake-charmers who resort to the island from the coast of Coromandel; and more than one well-authenticated instance of its successful application has been told to me by persons who had been eye-witnesses to what they described. On one occasion, in March, 1854, a friend of mine was riding, with some other civil officers of the Government, along a jungle path in the vicinity of Bintenne, when he saw one of two Tamils, who were approaching the party, suddenly dart into the forest and return, holding in both hands a cobra de capello which he had seized by the head and tail. He called to his companion for assistance to place it in their covered basket, but, in doing this, he handled it so inexpertly that it seized him by the finger, and retained its hold for a few seconds, as if unable to retract its fangs. The blood flowed, and intense pain appeared to follow almost immediately; but, with all expedition, the friend of the sufferer undid his waistcloth, and took from it two snake-stones, each of the size of a small almond, intensely black and highly polished, though of an extremely light substance. These he applied, one to each wound inflicted by the teeth of the serpent, to which they attached themselves closely; the blood that oozed from the bites being rapidly imbibed by the porous texture of the article applied. The stones adhered tenaciously for three or four minutes, the wounded man's companion in the meanwhile rubbing his arm downwards from the shoulder towards the fingers. At length the snake-stones dropped off of their own accord; the suffering of the man appeared to subside; he twisted his fingers till the joints cracked, and went on his way without concern. Whilst this had been going on, another Indian of the party who had come up took from his bag a small piece of white wood, which resembled a root, and passed it gently near the head of the cobra, which the latter immediately inclined close to the ground; he then lifted the snake without hesitation, and coiled it into a circle at the bottom of his basket. The root by which he professed to be enabled to perform this operation with safety he called the Naya-thalic Kalanga (the root of the snake-plant), protected by which he professed his ability to approach any reptile with impunity.
In another instance, in 1853, Mr. Lavalliere, then District Judge of Kandy, informed me that he saw a snake-charmer in the jungle, close by the town, search for a cobra de capello, and, after disturbing one in its retreat, the man tried to secure it, but, in the attempt, he was bitten in the thigh till blood trickled from the wound. He instantly applied the Pamboo-Kaloo, which adhered closely for about ten minutes, during which time he passed the root which he held in his hand backwards and forwards above the stone, till the latter dropped to the ground. He assured Mr. Lavalliere that all danger was then past. That gentleman obtained from him the snake-stone he had relied on, and saw him repeatedly afterwards in perfect health.
The substances used on both these occasions are now in my possession. The roots employed by the several parties are not identical. One appears to be a bit of the stem of an Aristolochia; the other is so dried as to render its identification difficult, but it resembles the quadrangular stem of a jungle vine. Some species of Aristolochia, such as the A. serpentaria of North America, are supposed to act as specifics in the cure of snakebites; and the A. indica is the plant to which the ichneumon is popularly believed to resort as an antidote when bitten[1]; but it is probable that the use of any particular plant by the snake-charmers is a pretence, or rather a delusion, the reptile being overpowered by the resolute action of the operator[2], and not by the influence of any secondary appliance. In other words, the confidence inspired by the supposed talisman enables its possessor to address himself fearlessly to his task, and thus to effect, by determination and will, what is popularly believed to be the result of charms and stupefaction. Still it is curious that, amongst the natives of Northern Africa, who lay hold of the Cerastes without fear or hesitation, impunity is ascribed to the use of a plant with the juice of which they anoint themselves before touching the reptile[3]; and Bruce says of the people of Sennar, that they acquire exemption from the fatal consequences of the bite by chewing a particular root, and washing themselves with an infusion of certain plants. He adds that a portion of this root was given him, with a view to test its efficacy in his own person, but that he had not sufficient resolution to make the experiment.
[Footnote 1: For an account of the encounter between the ichneumon and the venomous snakes of Ceylon, see Ch. I. p. 39.]
[Footnote 2: The following narrative of the operations of a snake-charmer in Ceylon is contained in a note from Mr. Reyne, of the department of public works: "A snake-charmer came to my bungalow in 1851, requesting me to allow him to show me his snakes dancing. As I had frequently seen them, I told him I would give him a rupee if he would accompany me to the jungle, and catch a cobra, that I knew frequented the place. He was willing, and as I was anxious to test the truth of the charm, I counted his tame snakes, and put a watch over them until I returned with him. Before going I examined the man, and satisfied myself he had no snake about his person. When we arrived at the spot, he played on a small pipe, and after persevering for some time out came a large cobra from an ant hill, which I knew it occupied. On seeing the man it tried to escape, but he caught it by the tail and kept swinging it round until we reached the bungalow. He then made it dance, but before long it bit him above the knee. He immediately bandaged the leg above the bite, and applied a snake-stone to the wound to extract the poison. He was in great pain for a few minutes, but after that it gradually went away, the stone falling off just before he was relieved. When he recovered he held a cloth up which the snake flew at, and caught its fangs in it; while in that position, the man passed his hand up its back, and having seized it by the throat, he extracted the fangs in my presence and gave them to me. He then squeezed out the poison on to a leaf. It was a clear oily substance, and when rubbed on the hand produced a fine lather. I carefully watched the whole operation, which was also witnessed by my clerk and two or three other persons. Colombo, 13th January 1860.—H.E. REYNE."]
[Footnote 3: Hasselquist.]
As to the snake-stone itself, I submitted one, the application of which I have been describing, to Mr. Faraday, who has communicated to me, as the result of his analysis, his belief that it is "a piece of charred bone which has been filled with blood perhaps several times, and then carefully charred again. Evidence of this is afforded, as well by the apertures of cells or tubes on its surface as by the fact that it yields and breaks, under pressure; and exhibits an organic structure within. When heated slightly, water rises from it, and also a little ammonia; and, if heated still more highly in the air, carbon burns away, and a bulky white ash is left, retaining the shape and size of the stone." This ash, as is evident from inspection, cannot have belonged toany vegetable substance, for it is almost entirely composed of phosphate of lime. Mr. Faraday adds that "if the piece of matter has ever been employed as a spongy absorbent, it seems hardly fit for that purpose in its present state: but who can say to what treatment it has been subjected since it was fit for use, or to what treatment the natives may submit it when expecting to have occasion to use it?"
The probability is, that the animal charcoal, when instantaneously applied, may be sufficiently porous and absorbent to extract the venom from the recent wound, together with a portion of the blood, before it has had time to be carried into the system; and that the blood which Mr. Faraday detected in the specimen submitted to him was that of the Indian on whose person the effect was exhibited on the occasion to which my informant was an eye-witness. The snake-charmers from the coast who visit Ceylon profess to prepare the snake-stones for themselves, and to preserve the composition a secret. Dr. Davy[1], on the authority of Sir Alexander Johnston, says the manufacture of them is a lucrative trade, carried on by the monks of Manilla, who supply the merchants of India—and his analysis confirms that of Mr. Faraday. Of the three different kinds which he examined—one being of partially burnt bone, and another of chalk, the third, consisting chiefly of vegetable matter, resembled bezoar,—all of them (except the first, which possessed a slight absorbent power) were quite inert, and incapable of having any effect except on the imagination of the patient. Thunberg was shown the snake-stone used by the boers at the Cape in 1772, which was imported for them "from the Indies, especially from Malabar," at so high a price that few of the farmers could afford to possess themselves of it; he describes it as convex on one side, black and so porous that "when thrown into water, it caused bubbles to rise;" and hence, by its absorbent qualities, it served, if speedily applied, to extract the poison from the wound.[2]
[Footnote 1: Account of the Interior of Ceylon, ch. iii. p. 101.]
[Footnote 2: Thunberg, vol. i. p. 155. Since the foregoing account was published, I have received a note from Mr. HARDY, relative to the piedra ponsona, the snake-stone of Mexico, in which he gives the following account of the method of preparing and applying it: "Take a piece of hart's horn of any convenient size and shape; cover it well round with grass or hay, enclose both in a thin piece of sheet copper well wrapped round them, and place the parcel in a charcoal fire till the bone is sufficiently charred.
"When cold, remove the calcined horn from its envelope, when it will be ready for immediate use. In this state it will resemble a solid black fibrous substance, of the same shape and size as before it was subjected to this treatment.
"USE.—The wound being slightly punctured, apply the bone to the opening, to which it will adhere firmly for the space of two minutes; and when it falls, it should be received into a basin of water. It should then be dried in a cloth, and again applied to the wound. But it will not adhere longer than about one minute. In like manner it may be applied a third time; but now it will fall almost immediately, and nothing will cause it to adhere any more.
"These effects I witnessed in the case of a bite of a rattle-snake at Oposura, a town in the province of Sonora, in Mexico, from whence I obtained my recipe; and I have given other particulars respecting it in my Travels in the Interior of Mexico, published in 1830. R.W.H. HARDY. Bath, 30th January, 1860."]
Coecilia.—The rocky jungle, bordering the higher coffee estates, provides a safe retreat for a very singular animal, first introduced to the notice of European naturalists about a century ago by Linnaeus, who gave it the name Coecilia glutinosa, to indicate two peculiarities manifest to the ordinary observer—an apparent defect of vision, from the eyes being so small and embedded as to be scarcely distinguishable; and a power of secreting from minute pores in the skin a viscous fluid, resembling that of snails, eels, and some salamanders. Specimens are rare in Europe owing to the readiness with which it decomposes, breaking down into a flaky mass in the spirits in which it is attempted to preserve it.
The creature is about the length and thickness of an ordinary round desk ruler, a little flattened before and rounded behind. It is brownish, with a pale stripe along either side. The skin is furrowed into 350 circular folds, in which are imbedded minute scales. The head is tolerably distinct, with a double row of fine curved teeth for seizing the insects and worms on which it is supposed to live.
Naturalists are most desirous that the habits and metamorphoses of this creature should be carefully ascertained, for great doubts have been entertained as to the position it is entitled to occupy in the chain of creation.
Batrachians.—In the numerous marshes formed by the overflowing of the rivers in the plains of the low country, there are many varieties of frogs, which, both by their colours and by their extraordinary size, are calculated to excite the surprise of a stranger. In the lakes around Colombo and the still water near Trincomalie, there are huge creatures of this family, from six to eight inches in length[1], of an olive hue, deepening into brown on the back and yellow on the under side. A Kandyan species, recently described, is of much smaller dimensions, but distinguished by its brilliant colouring, a beautiful grass green above and deep orange underneath[2].
[Footnote 1: A Singhalese variety of the Rana cutipora? and the Malabar bull-frog, Hylarana Malabarica. A frog named by BLYTH Rana robusta proves to be a Ceylon specimen of the R. cutipora.]
[Footnote 2: R. Kandiana, Kelaart.]
In the shrubberies around my house at Colombo the graceful little tree-frogs[1] were to be found in great numbers, sheltered under broad leaves to protect them from the scorching sun;—some of them utter a sharp metallic sound at night, similar to that produced by smacking the lips.
[Footnote 1: Polypedates maculatus, Gray.]
In the gardens and grounds toads[1] crouch in the shade, and pursue the flies and minute coleoptera. In Ceylon, as in Europe, these creatures suffer from the bad renown of injecting a poison into the wound inflicted by their bite.[2] The main calumny is confuted by the fact that no toad has yet been discovered furnished with any teeth whatsoever; but the obnoxious repute still attaches to the milky exudation sometimes perceptible from glands situated on either side behind the head; nevertheless experiments have shown, that though acrid, the secretions of the toad are incapable of exciting more than a slight erythema on the most delicate skins. The smell is, however, fetid and offensive, and hence toads are less exposed to the attacks of carnivorous animals and of birds than frogs, in which such glands do not exist.
[Footnote 1: Bufo melanostictus, Schneid.]
[Footnote 2: In Ceylon this error is as old as the third century, B.C., when, as the Mahawanso tells us, the wife of "King Asoka attempted to destroy the great bo-tree (at Magadha) with, the poisoned fang of a toad."—Ch. xx. p. 122.]
In the class of Reptiles, those only are included in the order of Batrachians which undergo a metamorphosis before attaining maturity; and as they offer the only example amongst Vertebrate animals of this marvellous transformation, they are justly considered as the lowest in the scale, with the exception of fishes, which remain during life in that stage of development which is only the commencement of existence to a frog.
In undergoing this change, it is chiefly the organs of respiration that manifest alteration. In its earliest form the young batrachian, living in the water, breathes as a fish does by gills, either free and projecting as in the water-newt, or partially covered by integument as in the tadpole. But the gills disappear as the lungs gradually become developed: the duration of the process being on an average one hundred days from the time the eggs were first deposited. After this important change, the true batrachian is incapable any longer of living continuously in water, and either betakes itself altogether to the land, or seeks the surface from time to time to replenish its exhausted lungs.[1]
[Footnote 1: A few Batrachians, such as the Siren of Carolina, the Proteus of Illyria, the Axolotl of Mexico, and the Menobranchus of the North American Lakes, retain their gills during life; but although provided with lungs in mature age, they are not capable of living out of the water. Such batrachians form an intermediate link between reptiles and fishes.]
The change in the digestive functions during metamorphosis is scarcely less extraordinary; frogs, for example, which feed on animal substances at maturity, subsist entirely upon vegetable when in the condition of larvae, and the subsidiary organs undergo remarkable development, the intestinal canal in the earlier stage being five times its length in the later one.
Of the family of tailed batrachians, Ceylon does not furnish a single example; but of those without this appendage, the island, as above remarked, affords many varieties; seven distinguishable species pertaining to the genus rana, or true frogs with webs to the hind feet; two to the genus bufo, or true toads, and five to the Polypedates, or East Indian "tree-frogs;" besides a few others in allied genera. The "tree-frog," whose toes are terminated by rounded discs which assist it in climbing, possesses, in a high degree, the faculty of changing its hues; and one as green as a leaf to-day, will be found grey and spotted like the bark to-morrow. One of these beautiful little creatures, which had seated itself on the gilt pillar of a lamp on my dinner-table, became in a few minutes scarcely distinguishable in colour from the or-molu ornament to which it clung.

CHAP. X.
FISHES.
Hitherto no branch of the zoology of Ceylon has been so imperfectly investigated as its Ichthyology. Little has been done in the examination and description of its fishes, especially those which frequent the rivers and inland waters. Mr. BENNETT, who was for some years employed in the Civil Service, directed his attention to the subject, and published in 1830 some portions of a projected work on the marine fishes of the island[1], but it never proceeded beyond the description of thirty individuals. The great work of Cuvier and Valenciennes[2] particularises about one hundred species, specimens of which were procured from Ceylon by Reynard, Leschenault and other correspondents; but of these not more than half a dozen belong to fresh water.
[Footnote 1: A Selection of the most Remarkable and Interesting Fishes found on the Coast of Ceylon. By J.W. BENNETT, Esp. London, 1830.]
[Footnote 2: Histoire Naturelle des Poissons.]
The fishes of the coast, as far as they have been examined, present few that are not in all probability common to the seas of Ceylon and India. A series of drawings, including upwards of six hundred species and varieties of Ceylon fish, all made from recently-captured specimens, have been submitted to Professor Huxley, and a notice of their general characteristics forms an interesting appendix to the present chapter.[1]
[Footnote 1: See note B appended to this chapter.]
Of those in ordinary use for the table the finest by far is the Seir-fish[1], a species of Scomberoids, which is called Tora-malu by the natives. It is in size and form very similar to the salmon, to which the flesh of the female fish, notwithstanding its white colour, bears a very close resemblance both in firmness and flavour.
[Footnote 1: Cybium (Scomber, Linn.) guttatum.]
Mackerel, carp, whitings, mullet both red and striped, perches and soles are abundant, and a sardine (Sardinella Neohowii, Val.) frequents the southern and eastern coast in such profusion that in one instance in 1839, a gentleman who was present saw upwards of four hundred thousand taken in a haul of the nets in the little bay of Goyapanna, east of Point-de-Galle. As this vast shoal approached the shore the broken water became as smooth as if a sheet of ice had been floating below the surface.[1]
[Footnote 1: These facts serve to explain the story told by the friar ODORIC of Friuli, who visited Ceylon about the year 1320 A.D., and says there are "fishes in those seas that come swimming towards the said country in such abundance that for a great distance into the sea nothing can be seen but the backs of fishes, which casting themselves on the shore, do suffer men for the space of three daies to come and to take as many of them as they please, and then they return again into the sea."—Hakluyt, vol. ii. p. 57.]
Poisonous Fishes.—The sardine has the reputation of being poisonous at certain seasons, and accidents ascribed to eating it are recorded in all parts of the island. Whole families of fishermen who have partaken of it have died. Twelve persons in the jail of Chilaw were thus poisoned, about the year 1829; and the deaths of soldiers have repeatedly been ascribed to the same cause. It is difficult in such instances to say with certainty whether the fish were in fault; whether there was not a peculiar susceptibility in the condition of the recipients; or whether the mischief may not have been occasioned by the wilful administration of poison, or its accidental occurrence in the brass cooking vessels used by the natives. The popular belief was, however, deferred to by an order passed by the Governor in Council in February, 1824, which, after reciting that "Whereas it appears by information conveyed to the Government that at three several periods at Trincomalie, death has been the consequence to several persons from eating the fish called Sardinia during the months of January and December," enacts that it shall not be lawful in that district to catch sardines during these months, under pain of fine and imprisonment. This order is still in force, but the fishing continues notwithstanding.[1]
[Footnote 1: There are other species of Sardine found at Ceylon besides the S. Neohowii; such as the S. lineolata, Cuv. and Val. and the S. leiogaster, Cuv. and Val. xx. 270, which was found by M. Reynaud at Trincomalie. It occurs also off the coast of Java. Another Ceylon fish of the same group, a Clupea, is known as the "poisonous sprat;" the bonito (Thynnus affinis, Cang.), the kangewena, or unicorn fish (Balistes?), and a number of others, are more or less in bad repute from the same imputation.]
Sharks.—Sharks appear on all parts of the coast, and instances continually occur of persons being seized by them whilst bathing even in the harbours of Trincomalie and Colombo. In the Gulf of Manaar they are taken for the sake of their oil, of which they yield such a quantity that "shark's oil" is a recognised export. A trade also exists in drying their fins, for which, owing to the gelatine contained in them, a ready market is found in China; whither the skin of the basking shark is also sent, to be converted, it is said, into shagreen.
Saw Fish.—The huge Pristis antiquorum[1] infests the eastern coast of the island, where it attains a length of from twelve to fifteen feet, including the serrated rostrum from which its name is derived. This powerful weapon seems designed to compensate for the inadequacy of the ordinary maxillary teeth which are unusually small, obtuse, and insufficient to capture and kill the animals which form the food of this predatory shark. To remedy this, the fore part of the head and its cartilages are prolonged into a flattened plate, the length of which is nearly equal to one third of the whole body, its edges being armed with formidable teeth, that are never shed or renewed, but increase in size with the growth of the creature.
[Footnote 1: Two other species are found in the Ceylon waters, P. cuspidatus and P. pectinatus.]
The Rays form a large tribe of cartilaginous fishes in which, although the skeleton is not osseous, the development of organs is so advanced that they would appear to be the highest of the class, approaching nearest to amphibians. They are easily distinguished from the sharks by their broad and flat body, the pectoral fins being expanded like wings on each side of the trunk. They are all inhabitants of the ocean, and some grow to a prodigious size. Specimens have been caught of twenty feet in breadth. These, however, are of rare occurrence, as such huge monsters usually retreat into the depths of the sea, where they are secure from the molestation of man. It is, generally speaking, only the young and the smaller species that approach the coasts, where they find a greater supply of those marine animals which form their food. The Rays have been divided into several generic groups, and the one of which a drawing (Aetobates narinari[1]) is given, has very marked characteristics in its produced snout, pointed and winged-like pectoral fins, and exceedingly long, flagelliform tail. The latter is armed with a strong, serrated spine, which is always broken off by the fishermen immediately on capture, under the impression that wounds inflicted by it are poisonous. Their fears, however, are utterly groundless, as the ray has no gland for secreting any venomous fluid. The apprehension may, however, have originated in the fact that a lacerated wound such as would be produced by a serrated spine, is not unlikely to assume a serious character, under the influence of a tropical climate. The species figured on the last page is brownish-olive on the upper surface, with numerous greenish-white round spots, darkening towards the edges. The anterior annulations of the tail are black and white, the posterior entirely black. Its mouth is transverse and paved with a band of flattened teeth calculated to crush the hard shells of the animals on which it feeds. It moves slowly along the bottom in search of its food, which consists of crustacea and mollusca, and seems to be unable to catch fishes or other quickly moving animals. Specimens have been taken near Ceylon, of six feet in width. Like most deep-sea fishes, the ray has a wide geographical range, and occurs not only in all the Indian Ocean, but also in the tropical tracts of the Atlantic.
[Footnote 1: Raja narinari, Bl. Schn. p. 361. Aetobates narinari, Muell. und Henle., Plagiost. p. 179.]
Another armed fish, renowned since the times of AElian and Pliny for its courage in attacking the whale, and even a ship, is the sword-fish (Xiphias gladius).[1] Like the thunny and bonito, it is an inhabitant of the deeper seas, and, though known in the Mediterranean, is chiefly confined to the tropics. The dangerous weapon with which nature has equipped it is formed by the prolongation and intertexture of the bones of the upper jaw into an exceedingly compact cylindrical protuberance, somewhat flattened at the base, but tapering to a sharp point. In strange inconsistence with its possession of so formidable an armature, the general disposition of the sword-fish is represented to be gentle and inoffensive; and although the fact of its assaults upon the whale has been incontestably established, yet the motive for such conflicts, and the causes of its enmity, are beyond conjecture. Competition for food is out of the question, as the Xiphias can find its own supplies without rivalry on the part of its gigantic antagonist; and as to converting the whale itself into food, the sword-fish, from the construction of its mouth and the small size of its teeth, is quite incapable of feeding on animals of such dimensions.
[Footnote 1: AELIAN tells a story of a ship in the Black Sea, the bottom of which was penetrated by the sword of a Xiphias (L. xiv. c. 23); and PLINY (L. xxxii. c. 8) speaks of a similar accident on the coast of Mauritania. In the British Museum there is a specimen of a plank of oak, pierced by a sword-fish, and still retaining the broken weapon.]
In the seas around Ceylon sword-fishes sometimes attain to the length of twenty feet, and are distinguished by the unusual height of the dorsal fin. Those both of the Atlantic and Mediterranean possess this fin in its full proportions, only during the earlier stages of their growth. Its dimensions even then are much smaller than in the Indian species; and it is a curious fact that it gradually decreases as the fish approaches to maturity; whereas in the seas around Ceylon, it retains its full size throughout the entire period of life. They raise it above the water, whilst dashing along the surface in their rapid course; and there is no reason to doubt that it occasionally acts as a sail.
The Indian species (which are provided with two long and filamentous ventral fins) have been formed into the genus Histiophorus; to which belongs the individual figured on the next page. It is distinguished from others most closely allied to it, by having the immense dorsal fin of one uniform dark violet colour; whilst in its congeners, it is spotted with blue. The fish from which the engraving has been made, was procured by Dr. Templeton, near Colombo. The species was previously known only by a single specimen captured in the Red Sea, by Rueppell, who conferred upon it the specific designation of "immaculatus."[1]
[Footnote 1: Trans. Zool. Soc. ii. p. 71. Pl. 15.]
AElian, in his graphic account of the strange forms presented by the fishes inhabiting the seas around Ceylon, says that one in particular is so grotesque in its configuration, that no painter would venture to depict it; its main peculiarity being that it has feet or claws rather than fins.[1] The annexed drawing[2] may probably represent the creature to which the informants of AElian referred. It is a cheironectes; one of a group in which the bones of the carpus form arms that support the pectoral fins, and enable these fishes to walk along the moist ground, almost like quadrupeds.
[Footnote 1: [Greek: Podas ge men chelas e pterygia.]—Lib. xvi. c. 18.]
[Footnote 2: The fish from which this drawing of the Cheironectes was made, was taken near Colombo, and from the peculiarities which it presents it is in all probability a new and undescribed species. Dr. GUeNTHER has remarked, that in it, whilst the first and second dorsal spines are situated as usual over the eye (and form, one the angling bait of the fish, the other the crest above the nose), the third is at an unusual distance from the second, and is not separated, as in the other species, from the soft fin by a notch.]
They belong to the family of Lophiads or "anglers," not unfrequent on the English coast; which conceal themselves in the mud, displaying only the erectile ray, situated on the head, which bears an excrescence on its extremity resembling a worm; by agitating which, they attract the smaller fishes, that thus become an easy prey.
On the rocks in Ceylon which are washed by the surf there are quantities of the curious little fish, Salarius alticus[1], which possesses the faculty of darting along the surface of the water, and running up the wet stones, with the utmost ease and rapidity. By aid of the pectoral and ventral fins and gill-cases, they move across the damp sand, ascend the roots of the mangroves, and climb up the smooth face of the rocks in search of flies; adhering so securely as not to be detached by repeated assaults of the waves. These little creatures are so nimble, that it is almost impossible to lay hold of them, as they scramble to the edge, and plunge into the sea on the slightest attempt to molest them. They are from three to four inches in length, and of a dark brown colour, almost undistinguishable from the rocks they frequent.
[Footnote 1: Cuv. and VALEN., Hist. Nat. des Poissons, tom. xi. p. 249. It is identical with S. tridactylus, Schn.]
But the most striking to the eye of a stranger are those fishes whose brilliancy of colouring has won for them the wonder even of the listless Singhalese. Some, like the Red Sea Perch (Holocentrum rubrum, Forsk) and the Great Fire Fish[1], are of the deepest scarlet and flame colour; in others purple predominates, as in the Serranus flavo-caeruleus; in others yellow, as in the Choetodon Brownriggii[2], and Acanthurus vittatus, of Bennett[3], and numbers, from the lustrous green of their scales, have obtained from the natives the appropriate name of Giraway, or parrots, of which one, the Sparus Hardwickii of Bennett, is called the "Flower Parrot," from its exquisite colouring, being barred with irregular bands of blue, crimson, and purple, green, yellow, and grey, and crossed by perpendicular stripes of black.
[Footnote 1: Pterois muricata, Cuv. and Val. iv. 363. Scarpaena miles, Bennett; named, by the Singhalese, "Maharata-gini," the Great Red Fire, a very brilliant red species spotted with black. It is very voracious, and is regarded on some parts of the coast as edible, while on others it is rejected.]
[Footnote 2: Glyphisodon Brownriggii, Cuv. and Val. v. 484; Choetodon Brownriggii, Bennett. A very small fish about two inches long, called Kaha hartikyha by the natives. It is distinct from Choetodon, in which BENNETT placed it. Numerous species of this genus are scattered throughout the Indian Ocean. It derives its name from the fine hair-like character of its teeth. They are found chiefly among coral reefs, and, though eaten, are not much esteemed. In the French colonies they are called "Chauffe-soleil." One species is found on the shores of the New World (G. saxatalis), and it is curious that Messrs. QUOY and GAIMARD found this fish at the Cape de Verde Islands in 1827.]
[Footnote 3: This fish has a sharp round spine on the side of the body near the tail; a formidable weapon, which is generally partially concealed within a scabbard-like incision. It raises or depresses this spine at pleasure. The fish is yellow, with several nearly parallel blue stripes on the back and sides; the belly is white, the tail and fins brownish green, edged with blue.
It is found in rocky places; and according to BENNETT, who has figured it in his second plate, it is named Seweya. It has been known, however, to all the old ichthyologists, Valentyn, Renard, Seba, Artedi, and has been named Chaetodon lineatus, by Linne. It is scarce on the southern coast of Ceylon.]
Of these richly coloured fishes the most familiar in the Indian seas are the Pteroids. They are well known on the coast of Africa, and thence eastward to Polynesia; but they do not extend to the west coast of America, and are utterly absent from the Atlantic. The rays of the dorsal and pectoral fins are so elongated, that when specimens were first brought to Europe it was conjectured that these fishes have the faculty of flight, and hence the specific name of "volitans" But this is an error, for, owing to the deep incisions between the pectoral rays, the pteroids are wholly unable to sustain themselves in the air. They are not even bold swimmers, living close to the shore and never venturing into the deep sea. Their head is ornamented with a number of filaments and cutaneous appendages, of which one over each eye and another at the angles of the mouth are the most conspicuous. Sharp spines project on the crown and on the side of the gill-apparatus, as in the other sea-perches, Scorpaena, Serranus, &c., of which these are only a modified and ornate form. The extraordinary expansion of their fins is not, however, accompanied by a similar development of the bones to which they are attached, simply because they appear to have no peculiar function, as in flying fishes, or in those where the spines of the fins are weapons of offence. They attain to the length of twelve inches, and to a weight of about two pounds; they live on small marine animals, and by the Singhalese the flesh (of some at least) is considered good for table. Nine or ten species are known to occur in the East Indian Seas, and of these the one figured above is, perhaps, the most common.
Another species known to occur on the coasts of Ceylon is the Scorpaena miles, Bennett, or Pterois miles, Guenther[1], of which Bennett has given a figure[2], but it is not altogether correct in some particulars.
[Footnote 1: The fish from the Sea of Pinang, described by Dr. CANTOR with this name (Catal. Mal. Fish. p. 42), is again different, and belongs to a third species.]
[Footnote 2: Fishes of Ceylon, Pl. ix.]
In the fishes of Ceylon, however, beauty is not confined to the brilliancy of their tints. In some, as in the /Scarus harid, Forsk[1], the arrangement of the scales is so graceful, and the effect is so heightened by modifications of colour, as to present the appearance of tessellation, or mosaic work.
[Footnote 1: This is the fish figured by BENNETT as Sparus pepo. Fishes of Ceylon, Plate xxviii.]
Fresh-water Fishes.—Of the fresh-water fish, which inhabit the rivers and tanks, so very little has hitherto been known to naturalists[1], that of nineteen drawings sent home by Major Skinner in 1852, although specimens of well-known genera, Colonel Hamilton Smith pronounced nearly the whole to be new and undescribed species.
[Footnote 1: In extenuation of the little that is known of the fresh-water fishes of Ceylon, it may be observed that very few of them are used at table by Europeans, and there is therefore no stimulus on the part of the natives to catch them. The burbot and grey mullet are occasionally eaten, but they taste of mud, and are not in request.
Some years ago the experiment was made, with success, of introducing into Mauritius the Osphromenus olfax of Java, which has also been taken to French Guiana. In both places it is now highly esteemed as a fish for table. As it belongs to a family which possesses the faculty, hereafter alluded to, of surviving in the damp soil after the subsidence of the water in the tanks and rivers, it might with equal advantage be acclimated in Ceylon. It grows to 20 lbs. weight and upwards.]
Of eight of these, which were from the Mahawelliganga, and caught in the vicinity of Kandy, five were carps; two were Leucisci, and one a Mastacembelus (M. armatus, Lacep); one was an Ophiocephalus, and one a Polyacanthus, with no serrae on the gills. Six were from the Kalanyganga, close to Colombo, of which two were Helostoma, in shape approaching the Chaetodon; two Ophiocephali, one a Silurus, and one an Anabas, but the gills were without denticulation. From the still water of the lake, close to the walls of Colombo, there were two species of Eleotris, one Silurus with barbels, and two Malacopterygians, which appear to be Bagri.
The fresh-water Perches of Europe and of the North of America are represented in Ceylon and India by several genera, which bear to them a great external similarity (Lates, Therapon). They have the same habits as their European allies, and their flesh is considered equally wholesome, but they appear to enter salt-water, or at least brackish water, more freely. It is, however, in their internal organisation that they differ most from the perches of Europe; their skeletons are composed of fewer vertebrae, and the air bladder of the Therapon is divided into two portions, as in the carps. Four species at least of this genus inhabit the lakes and rivers of Ceylon, and one of them, of which a figure is given above, has been but imperfectly described in any ichthyological work[1]; it attains to the length of seven inches.
[Footnote 1: Holocentrus quadrilineatus, Bloch. It is allied to Helotes polytoenia, Bleek., from Halmaheira which it can be readily distinguished by having only five or six blackish longitudinal bands, the black humeral spot being between the first and second; another blackish blotch is in the spinous dorsal fin. There are two specimens in the British Museum collection, one of which has recently arrived from Amoy; of the other the locality is unknown. See GUeNTHER, Acanthopt. Fishes, vol. i. p. 282, where mention of the black humeral spot has been omitted.]
In addition to marine eels, in which the Indian coasts abound, Ceylon has some true fresh-water eels, which never enter the sea. These are known to the natives under the name of Theliya, and to naturalists by that of Mastacembelus. They have sometimes in ichthyological systems been referred to the Scombridae and other marine families, from the circumstance that the dorsal fin anteriorly is composed of spines. But, in addition to the general shape of the body, their affinity to the eel is attested, by their confluent fins, by the absence of ventral fins, by the structure of the mouth and its dentition, by the apparatus of the gills, which opens with an inferior slit, and above all by the formation of the skeleton itself.[1]
[Footnote 1: See GUeNTHER'S Acanthopt. Fishes, vol. iii. (Family Mastacembelidae).]
Their skin is covered with minute scales, coated by a slimy exudation, and the upper jaw is produced into a soft tripartite tentacle, with which they are enabled to feel for their prey in the mud. They are very tenacious of life, and belong, without doubt, to those fishes which in Ceylon descend during the drought into the muddy soil.[1] Their flesh very much resembles that of the eel; and is highly esteemed.[2] They were first made known to European naturalists by Russell[3], who brought to Europe from the rivers round Aleppo specimens, some of which are still preserved in the collection of the British Museum. Aleppo is the most western point of their geographical range, the group being mainly confined to the East-Indian continent and its islands.
In Ceylon only one species appears to occur, the

[Footnote 3: Nat. Hist. Aleppo, 2nd edit. Lond. 1794, vol. ii. p. 208, pl. vi.]
Mastacembelus armatus.[1] The back is armed with from thirty-five to thirty-nine short, stout spines; there being three others before the anal fin. The ground colour of the fish is brown, and the head has two rather irregular longitudinal black bands; deep-brown spots run along the back as well as along the dorsal and anal fins; and the sides are ornamented with irregular and reticulated brown lines. This eel attains to the length of two feet. The old females do not show any markings, being of a uniform brown colour.

In the collection of Major Skinner, before alluded to, brought together without premeditation, the naturalist will be struck by the preponderance of those genera which are adapted by nature to endure, a temporary privation of moisture; and this, taken in connection with the vicissitudes affecting the waters they inhabit, exhibits a surprising illustration of the wisdom of the Creator in adapting the organisation of his creatures to the peculiar circumstances under which they are destined to exist.
So abundant are fish in all parts of the island, that Knox says, not the running streams alone, but the reservoirs and ponds, "nay, every ditch and little plash of water but ankle deep hath fish in it."[1] But many of these reservoirs and tanks are, twice in each year, liable to be evaporated to dryness till the mud of the bottom is converted into dust, and the clay cleft by the heat into gaping apertures; yet within a very few days after the change of the monsoon, the natives are busily engaged in fishing in those very spots and in the hollows contiguous to them, although the latter are entirely unconnected with any pool or running streams. Here they fish in the same way which Knox described nearly 200 years ago, with a funnel-shaped basket, open at bottom and top, "which," as he says, "they jibb down, and the end sticks in the mud, which often happens upon a fish; which, when they feel beating itself against the sides, they put in their hands and take it out, and reive a ratan through their gills, and so let them drag after them."[2]
[Footnote 1: Knox's Historical Relation of Ceylon, Part i. ch. vii. The occurrence of fish in the most unlooked-for situations, is one of the mysteries of other eastern countries as well as Ceylon and India. In Persia irrigation is carried on to a great extent by means of wells sunk in line in the direction in which it is desired to lead a supply of water, and these are connected by channels, which are carefully arched over to protect them from evaporation. These kanats, as they are called, are full of fish, although neither they nor the wells they unite have any connection with streams or lakes.]
[Footnote 2: Knox, Historical Relation of Ceylon, Part i. ch vi.]
This operation may be seen in the lowlands, traversed by the high road leading from Colombo to Kandy. Before the change of the monsoon, the hollows on either side of the highway are covered with dust or stunted grass; but when flooded by the rains, they are immediately resorted to by the peasants with baskets, constructed precisely as Knox has stated, in which the fish are entrapped and taken out by the hand.[1]
[Footnote 1: As anglers, the native Singhalese exhibit little expertness; but for fishing the rivers, they construct with singular ingenuity fences formed of strong stakes, protected by screens of ratan, that stretch diagonally across the current; and along these the fish are conducted into a series of enclosures from which retreat is impracticable. MR. LAYARD, in the Magazine of Natural History for May, 1853, has given a diagram of one of these fish "corrals," as they are called, of which a copy is shown on the next page.]
So singular a phenomenon as the sudden re-appearance of full-grown fishes in places that a few days before had been encrusted with hardened clay, has not failed to attract attention; but the European residents have been content to explain it by hazarding conjectures, either that the spawn must have lain imbedded in the dried earth till released by the rains, or that the fish, so unexpectedly discovered, fall from the clouds during the deluge of the monsoon.
As to the latter conjecture; the fall of fish during showers, even were it not so problematical in theory, is too rare an event to account for the punctual appearance of those found in the rice-fields, at stated periods of the year. Both at Galle and Colombo in the south-west monsoon, fish are popularly believed to have fallen from the clouds during violent showers, but those found on the occasions that give rise to this belief, consist of the smallest fry, such as could be caught up by waterspouts, and vortices analogous to them, or otherwise blown on shore from the surf; whereas those which suddenly appear in the replenished tanks and in the hollows which they overflow, are mature and well-grown fish.[1] Besides, the latter are found, under the circumstances I have described, in all parts of the interior, whilst the prodigy of a supposed fall of fish from the sky has been noticed, I apprehend, only in the vicinity of the sea, or of some inland water.
[Footnote 1: I had an opportunity, on one occasion only, of witnessing the phenomenon which gives rise to this popular belief. I was driving in the cinnamon gardens near the fort of Colombo, and saw a violent but partial shower descend at no great distance before me. On coming to the spot I found a multitude of small silvery fish from one and a half to two inches in length, leaping on the gravel of the high road, numbers of which I collected and brought away in my palankin. The spot was about half a mile from the sea, and entirely unconnected with any watercourse or pool.
Mr. Whiting, who was many years resident in Trincomadie, writes me that he "had often been told by the natives on that side of the island that it sometimes rained fishes; and on one occasion" (he adds) "I was taken by them, in 1849, to a field at the village of Karrancotta-tivo, near Batticaloa, which was dry when I passed over it in the morning, but, had been covered in two hours by sudden rain to the depth of three inches, in which there was then a quantity of small fish. The water had no connection with any pond or stream whatsoever." Mr. Cripps, in like manner, in speaking of Galle, says: "I have seen in the vicinity of the fort, fish taken from rain-water that had accumulated in the hollow parts of land that in the hot season are perfectly dry and parched. The place is accessible to no running stream or tank; and either the fish or the spawn from which they were produced, must of necessity have fallen with the rain."
Mr. J. PRINSEP, the eminent secretary to the Asiatic Society of Bengal, found a fish in the pulviometer at Calcutta, in 1838.—Journ. Asiat. Soc. Bengal, vol. vi. p. 465.
A series of instances in which fishes have been found on the continent of India under circumstances which lead to the conclusion that they must have fallen from the clouds, have been collected by the late Dr. BUIST of Bombay, and will be found in the appendix to this chapter.]
The surmise of the buried spawn is one sanctioned by the very highest authority. Mr. Yarrell in his "History of British Fishes," adverting to the fact that ponds (in India) which had been previously converted into hardened mud, are replenished with small fish in a very few days after the commencement of each rainy season, offers this solution of the problem as probably the true one: "The impregnated ova of the fish of one rainy season are left unhatched in the mud through the dry season, and from their low state of organisation as ova, the vitality is preserved till the recurrence, and contact of the rain and oxygen in the next wet season, when vivification takes place from their joint influence."[1]
[Footnote 1: YARRELL, History of British Fishes, introd. vol. i. p. xxvi. This too was the opinion of Aristotle, De Respiratione, c. ix.]
This hypothesis, however, appears to have been advanced upon imperfect data; for although some fish, like the salmon, scrape grooves in the sand and place their spawn in inequalities and fissures; yet as a general rule spawn is deposited not beneath but on the surface of the ground or sand over which the water flows, the adhesive nature of each egg supplying the means of attachment. But in the Ceylon tanks not only is the surface of the soil dried to dust after the evaporation of the water, but earth itself, twelve or eighteen inches deep, is converted into sun-burnt clay, in which, although the eggs of mollusca, in their calcareous covering, are in some instances preserved, it would appear to be as impossible for the ova of fish to be kept from decomposition as for the fish themselves to sustain life. Besides, moisture in such situations is only to be found at a depth to which spawn could not be conveyed by the parent fish, by any means with which we are yet acquainted. |
