Sketches of the Natural History of Ceylon
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."
To the foregoing observations I have little to add beyond my acknowledgment to Dr. ALBERT G&ÜNTHER, of the British Museum, for the communication of important facts in illustration of the ichthyology of Ceylon, as well as of the reptiles of the island.
Mr. BLYTH, of the Calcutta Museum, has carefully revised the Catalogue of Birds, and supplied me with much useful information in regard to their geographical distribution. To his experienced scrutiny is due the perfected state in which the list is now presented. It will be seen, however, from the italicised names still retained, that inquiry is far from being exhausted.
Mr. THWAITES, the able Director of the Royal Botanic Gardens at Peradenia, near Kandy, has forwarded to me many valuable observations, not only in connection with the botany, but the zoology of the mountain region. The latter I have here embodied in their appropriate places, and those relating to plants and vegetation will appear in a future edition of my large work.
To M. NIETNER, of Colombo, I am likewise indebted for many particulars regarding Singhalese Entomology, a department to which his attention has been given, with equal earnestness and success.
Through the Hon. RICHARD MORGAN, acting Senior Puisne Judge of the Supreme Court at Colombo, I have received from his Interpreter, M.D. DE SILVA GOONERATNE MODLIAR, a Singhalese gentleman of learning and observation, many important notes, of which I have largely availed myself, in relation to the wild animals, and the folk-lore and superstitions of the natives in connection with them.
Of the latter I have inserted numerous examples; in the conviction that, notwithstanding their obvious errors in many instances, these popular legends and traditions occasionally embody traces of actual observation, and may contain hints and materials deserving of minuter inquiry.
I wish distinctly to disclaim offering the present volume as a compendium of the Natural History of Ceylon. I present it merely as a "mémoire pour servir," materials to assist some future inquirer in the formation of a more detailed and systematic account of the fauna of the island. My design has been to point out to others the extreme richness and variety of the field, the facility of exploring it, and the charms and attractions of the undertaking. I am eager to show how much remains to do by exhibiting the little that has as yet been done.
The departments of Mammalia and Birds are the only two which can be said to have as yet undergone tolerably close investigation; although even in these it is probable that large additions still remain to be made to the ascertained species. But, independently of forms and specific characteristics, the more interesting inquiry into habits and instincts is still open for observation and remark; and for the investigation of these no country can possibly afford more inviting opportunities than Ceylon.
Concerning the Reptilia a considerable amount of information has been amassed. The Batrachians and smaller Lizards have, I apprehend, been imperfectly investigated; but the Tortoises are well known, and the Serpents, from the fearful interest attaching to the race, and stimulating their destruction, have been so vigilantly pursued, that there is reason to believe that few, if any, varieties exist which have not been carefully examined. In a very large collection, made by Mr. CHARLES REGINALD BULLER during many years' residence in Kandy, and recently submitted by him to Dr. Günther, only one single specimen proved to be new or previously unknown to belong to the island.
Of the Ichthyology of Ceylon I am obliged to speak ill very different terms; for although the materials are abundant almost to profusion, little has yet been done to bring them under thoroughly scientific scrutiny. In the following pages I have alluded to the large collection of examples of Fishes sent home by officers of the Medical Staff, and which still remain unopened, in the Fort Pitt Museum at Chatham; but I am not without hope that these may shortly undergo comparison with the drawings which exist of each, and that this branch of the island fauna may at last attract the attention to which its richness so eminently entitles it.
In the department of Entomology much has already been achieved; but an extended area still invites future explorers; and one which the Notes of Mr. Walker prefixed to the List of Insects in this volume, show to be of extraordinary interest, from the unexpected convergence in Ceylon of characteristics heretofore supposed to have been kept distinct by the broad lines of geographical distribution.
Relative to the inferior classes of Invertebrata very little has as yet been ascertained. The Mollusca, especially the lacustrine and fluviatile, have been most imperfectly investigated; and of the land-shells, a large proportion have yet to be submitted to scientific examination.
The same may be said of the Arachnida and Crustacea. The jungle is frequented by spiders, phalangia6, and acarids, of which nothing is known with certainty; and the sea-shore and sands have been equally overlooked, so far as concerns the infinite variety of lobsters, crayfish, crabs, and all their minor congeners. The polypi, echini, asterias, and other radiata of the coast, as well as the acalephæ of the deeper waters, have shared the same neglect: and literally nothing has been done to collect and classify the infusoriæ and minuter zoophytes, the labours of Dr. Kelaart amongst the Diatomaceæ being the solitary exception.
Nothing is so likely to act as a stimulant to future research as an accurate conception of what has already been achieved. With equal terseness and truth Dr. Johnson has observed that the traveller who would bring back knowledge from any country must carry knowledge with him at setting out: and I am not without hope that the demonstration I now venture to offer, of the little that has already been done for zoology in Ceylon, may serve to inspire others with a desire to resume and complete the inquiry.
