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 into Africa, Australia, and the isles of the Eastern Archipelago.

The author was never, I believe, in Ceylon, but his book is a laborious condensation of the principal English works relating to it.

Its value would have been greatly increased had Mr.Pridham accompanied his excerpts by references to the respective authorities.] 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 journies 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 of animals.

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.
