A suggestion to re-publish these sections in an independent form has afforded an opportunity for repairing some of these defects by revising the entire, restoring omitted passages, and introducing fresh materials collected in Ceylon; the additional matter occupying a very large portion of the present volume.
I have been enabled, at the same time, to avail myself of the corrections and communications of scientific friends; and thus to compensate, in some degree for what is still incomplete, by increased accuracy in minute particulars.
In the Introduction to the First Edition of the original work I alluded, in the following terms, to that portion of it which is now reproduced in an extended form:—
"Regarding the fauna of Ceylon, little has been published in any collective form, with the exception of a volume by Dr. KELAART entitled Prodromus Faunæ Zeilanicæ; several valuable papers by Mr. EDGAR L. LAYARD in the Annals and Magazine of Natural History for 1852 and 1853; and some very imperfect lists appended to PRIDHAM'S compiled account of the island.[2] KNOX, in the charming narrative of his captivity, published in the feign of Charles II., has devoted a chapter to the animals of Ceylon, and Dr. DAVY has described some of the reptiles: but with these exceptions the subject is almost untouched in works relating to the colony. Yet a more than ordinary interest attaches to the inquiry, since Ceylon, instead of presenting, as is generally assumed, an identity between its fauna and that of Southern India, exhibits a remarkable diversity, taken in connection with the limited area over which the animals included in it are distributed. The island, in fact, may be regarded as the centre of a geographical circle, possessing within itself forms, whose allied species radiate far into the temperate regions of the north, as well as in to Africa, Australia, and the isles of the Eastern Archipelago.
"In the chapters that I have devoted to its elucidation, I have endeavoured to interest others in the subject, by describing my own observations and impressions, with fidelity, and with as much accuracy as may be expected from a person possessing, as I do, no greater knowledge of zoology and the other physical sciences than is ordinarily possessed by any educated gentleman. It was my good fortune, however, in my journeys to have the companionship of friends familiar with many branches of natural science: the late Dr. GARDNER, Mr. EDGAR L. LAYARD, an accomplished zoologist, Dr. TEMPLETON, and others; and I was thus enabled to collect on the spot many interesting facts relative to the structure and habits of the numerous tribes. These, chastened by the corrections of my fellow-travellers, and established by the examination of collections made in the colony, and by subsequent comparison with specimens contained in museums at home, I have ventured to submit as faithful outlines of the fauna of Ceylon.
"The sections descriptive of the several classes are accompanied by lists, prepared with the assistance of scientific friends, showing the extent to which each particular branch had been investigated by naturalists, up to the period of my departure from Ceylon at the close of 1849. These, besides their inherent interest, will, I trust, stimulate others to engage in the same pursuit, by exhibiting chasms, which it remains for future industry and research to fill up;—and the study of the zoology of Ceylon may thus serve as a preparative for that of Continental India, embracing, as the former does, much that is common to both, as well as possessing a fauna peculiar to the island, that in itself will amply repay more extended scrutiny.
"From these lists have been excluded all species regarding the authenticity of which reasonable doubts could be entertained[3], and of some of them, a very few have been printed in italics, in order to denote the desirability of more minute comparison with well-determined specimens in the great national depositories before finally incorporating them with the Singhalese catalogues.
"In the labour of collecting and verifying the facts embodied in these sections, I cannot too warmly express my thanks for the aid I have received from gentlemen interested in similar studies in Ceylon: from Dr. KELAART[4] and Mr. EDGAR L. LAYARD, as well as from officers of the Ceylon Civil Service; the Hon. GERALD C. TALBOT, Mr. C.R. BULLER, Mr. MERCER, Mr. MORRIS, Mr. WHITING, Major SKINNER, and Mr. MITFORD.
"Before venturing to commit these chapters of my work to the press, I have had the advantage of having portions of them read by Professor HUXLEY, Mr. MOORE, of the East India House Museum; Mr. R. PATTERSON, F.R.S., author of the Introduction to Zoology; and by Mr. ADAM WHITE, of the British Museum; to each of whom I am exceedingly indebted for the care they have bestowed. In an especial degree I have to acknowledge the kindness of Dr. J.E. GRAY, F.R.S., for valuable additions and corrections in the list of the Ceylon Reptilia; and to Professor FARADAY for some notes on the nature and qualities of the "Serpent Stone,"[5] submitted to him.
"The extent to which my observations on the Elephant have been carried, requires some explanation. The existing notices of this noble creature are chiefly devoted to its habits and capabilities in captivity; and very few works, with which I am acquainted, contain illustrations of its instincts and functions when wild in its native woods. Opportunities for observing the latter, and for collecting facts in connection with them, are abundant in Ceylon; and from the moment of my arrival, I profited by every occasion afforded to me for observing the elephant in a state of nature, and obtaining from hunters and natives correct information as to its oeconomy and disposition. Anecdotes in connection with this subject, I received from some of the most experienced residents in the island; amongst others, from Major SKINNER, Captain PHILIP PAYNE GALLWEY, Mr. FAIRHOLME, Mr. CRIPPS, and Mr. MORRIS. Nor can I omit to express my acknowledgments to Professor OWEN, of the British Museum, to whom this portion of my manuscript was submitted previous to its committal to the press."
