INTRODUCTION. A CONSIDERABLE portion of the contents of the present volume formed the zoological section of a much more comprehensive work recently published, on the history and present condition of Ceylon. But its inclusion there was a matter of difficulty; for to have altogether omitted the chapters on Natural History would have impaired the completeness of the plan on which I had attempted to describe the island; whilst to insert them as they here appear, without curtailment, would have encroached unduly on the space required for other essential topics. In this dilemma, I was obliged to adopt the alternative of so condensing the matter as to bring the whole within the prescribed proportions. But this operation necessarily diminished the general interest of the subjects treated, as well by the omission of incidents which would otherwise have been retained, as by the exclusion of anecdotes calculated to illustrate the habits and instincts of the animals described. 1 Ceylon: An Account of the Island, Physical, Historical, and Topographical; with Notices of its Natural History, Antiquities, and Productions. By Sir JAMES EMER A S SON TENNENT, K.C.S., LL.D., &c. 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 Fauna Zeilanica; 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.1 KNOX, in the charming narrative of his captivity, published in the reign 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 1 An Historical, Political, and Statistical Account of Ceylon and its Dependencies, by C. PRIDHAM, Esq. 2 vols. 8vo. London, 1849. The island, 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. 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 into 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', 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 1 An exception occurs in the list of shells, prepared by Mr. SYLVANUS HANLEY, in which some whose loca lities are doubtful have been admitted for reasons adduced.
