VII. PACHYDERMATA.--_The Elephant_.--The elephant, and the wild boar, the Singhalese ”waloora,”[1] are the only representatives of the _pachydermatous_ order. The latter, which differs somewhat from the wild boar of India, is found in droves in all parts of the island where vegetation and water are abundant.
[Footnote 1: Mr. BLYTH of Calcutta has distinguished, from the hog, common in India, a specimen sent to him from Ceylon, the skull of which approaches in form, that of a species from Borneo, the _susbarbatus_ of S. Muller.]
The elephant, the lord paramount of the Ceylon forests, is to be met with in every district, on the confines of the woods, in the depths of which he finds concealment and shade during the hours when the sun is high, and from which he emerges only at twilight to wend his way towards the rivers and tanks, where he luxuriates till dawn, when he again seeks the retirement of the deep forests. This n.o.ble animal fills so dignified a place both in the zoology and oeconomy of Ceylon, and his habits in a state of nature have been so much misunderstood, that I shall devote a separate section to his defence from misrepresentation, and to an exposition of what, from observation and experience, I believe to be his genuine character when free in his native domains. But this seems the proper place to allude to a recent discovery in connexion with the elephant, which strikingly confirms a conjecture which I ventured to make elsewhere[1], relative to the isolation of Ceylon and its distinctness, in many remarkable particulars, from the great continent of India. Every writer who previously treated of the island, including the accomplished Dr. Davy and the erudite La.s.sen, was contented, by a glance at its outline and a reference to its position on the map, to a.s.sume that Ceylon was a fragment, which in a very remote age had been torn from the adjacent mainland, by some convulsion of nature. Hence it was taken for granted that the vegetation which covers and the races of animals which inhabit it, must be identical with those of Hindustan; to which Ceylon was alleged to bear the same relation as Sicily presents to the peninsula of Italy. MALTE BRUN[2] and the geographers generally, declared the larger animals of either to be common to both. I was led to question the soundness of this dictum;--and from a closer examination of its geological conformation and of its botanical and zoological characteristics I came to the conclusion that not only is there an absence of sameness between the formations of the two localities; but that plants and animals, mammals, birds, reptiles, and insects exist in Ceylon, which are not to be found in the flora and fauna of the Dekkan; but which present a striking affinity, and occasionally an actual ident.i.ty, with those of the Malayan countries and some of the islands of the Eastern Archipelago. Startling as this conclusion appeared to be, it was strangely in unison with the legends of the Singhalese themselves, that at an infinitely remote period Ceylon formed an integral portion of a vast continent, known in the mythical epics of the Brahmans by the designation of ”_Lanka_;” so immense that its southern extremity fell below the equator, whilst in breadth it was prolonged till its western and eastern boundaries touch at once upon the sh.o.r.es of Africa and China.

Dim as is this ancient tradition, it is in consistency with the conclusions of modern geology, that at the commencement of the tertiary period northern Asia and a considerable part of India were in all probability covered by the sea but that south of India land extended eastward and westward connecting Malacca with Arabia. PROFESSOR ANSTED has propounded this view. His opinion is, that the Himalayas then existed only as a chain of islands, and did not till a much later age become elevated into mountain ranges,--a change which took place during the same revolution that raised the great plains of Siberia and Tartary and many parts of north-western Europe. At the same time the great continent whose position between the tropics has been alluded to, and whose previous existence is still indicated by the Coral islands, the Laccadives, the Maldives, and the Chagos group, underwent simultaneous depression by a counteracting movement.[1]

But divested of oriental mystery and geologic conjecture, and brought to the test of ”geographical distribution,” this once prodigious continent would appear to have connected the distant Islands of Ceylon and Sumatra and possibly to have united both to the Malay peninsula, from which the latter is now severed by the Straits of Malacca. The proofs of physical affinity between these scattered localities are exceedingly curious.
A striking dissimilarity presents itself between some of the Mammalia of Ceylon and those of the continent of India. In its general outline and feature, this branch of the island fauna, no doubt, exhibits a general resemblance to that of the mainland, although many of the larger animals of the latter are unknown in Ceylon: but, on the other hand, some species discovered there are peculiar to the island. A deer[1] as large as the Axis, but differing from it in the number and arrangement of its spots, has been described by Dr. Kelaart, to whose vigilance the natural history of Ceylon is indebted, amongst others, for the identification of two new species of monkeys[2], a number of curious shrews[3], and an orange-coloured ichneumon[4], before unknown. There are also two squirrels[5] that have not as yet been discovered elsewhere, (one of them belonging to those equipped with a parachute[6],) as well as some local varieties of the palm squirrel (Sciurus penicillatus, _Leach_).[7]

[Footnote 7: There is a rat found only in the Cinnamon Gardens at Colombo, Mus Ceylonus, _Kelaart_; and a mouse which Dr. Kelaart discovered at Trincomalie, M. fulvidiventris, _Blyth_, both peculiar to Ceylon. Dr. TEMPLETON has noticed a little shrew (Corsira purpurascens, _Mag. Nat. Hist_. 1855, p. 238) at Neuera-ellia, not as yet observed elsewhere.]
But the Ceylon Mammalia, besides wanting a number of minor animals found in the Indian peninsula, cannot boast such a ruminant as the majestic Gaur[1], which inhabits the great forests from Cape Comorin to the Himalaya; and, providentially, the island is equally free of the formidable tiger and the ferocious wolf of Hindustan. The Hyena and Cheetah[2], common in Southern India, are unknown in Ceylon; and, though abundant in deer, the island possesses no example of the Antelope or the Gazelle.

Amongst the Birds of Ceylon, the same abnormity is apparent. About thirty-eight species will be presently particularised[1], which, although some of them may hereafter be discovered to have a wider geographical range, are at present believed to be unknown in continental India. I might further extend this enumeration, by including the Cheela eagle of Ceylon, which, although I have placed it in my list as identical with the _Hematornis cheela_ of the Dekkan, is, I have since been a.s.sured, a different bird, and is most probably the _Falco bido_ of Horsfield, known to us by specimens obtained from Java and Sumatra.
[Footnote 1: See Chapter on the Birds of Ceylon.]
As to the Fishes of Ceylon, they are of course less distinct; and besides they have hitherto been very imperfectly compared. But the Insects afford a remarkable confirmation of the view I have ventured to propound; so much so that Mr. Walker, by whom the elaborate lists appended to this work have been prepared, a.s.serts that some of the families have a less affinity to the entomology of India than to that of Australia.[1]
