Of the family of tailed batrachians, Ceylon does not furnish a single example; but of those without this appendage, the island, as above remarked, affords many varieties; seven distinguishable species pertaining to the genus _rana_, or true frogs with webs to the hind feet; two to the genus _bufo_, or true toads, and five to the _Polypedates_, or East Indian "tree-frogs;" besides a few others in allied genera. The "tree-frog," whose toes are terminated by rounded discs which assist it in climbing, possesses, in a high degree, the faculty of changing its hues; and one as green as a leaf to-day, will be found grey and spotted like the bark to-morrow. One of these beautiful little creatures, which had seated itself on the gilt pillar of a lamp on my dinner-table, became in a few minutes scarcely distinguishable in colour from the or-molu ornament to which it clung. * * * * * _List of Ceylon Reptiles._ I am indebted to Dr. Gray and Dr. Günther, of the British Museum, for a list of the reptiles of Ceylon; but many of those new to Europeans have been carefully described by the late Dr. Kelaart in his _Prodromus Fauna Zeylanicæ_ and its appendices, as well as in the 13th vol. _Magaz.
