Rh ing these questions in the affirmative than the negative, but they must be determined by ascertaining the facts, in order to know the exact boundaries of the range of E. indicus.

If, as we have reason to believe is the case, the Elephant of Southern India agrees with that of Bengal, then the phenomenon that the Ceylonese animal belongs to another species, and that species the Sumatran, is certainly very remarkable. The Fauna of Ceylon shows, it is true, in some respects, differences from that of Southern India; one of the most noticeable of which is, that not one of the Monkeys living upon this island is identical with those of India. Nevertheless the Fauna of Ceylon agrees much better with that of India than with that of Sumatra, where not only entirely different species, but even other forms of Monkeys occur (e.g. the Orangoutang, several Gibbons, amongst which is the abnormal Hylobates syndactylus, the Galeopithecus, &c.) and which island besides produces, to mention some of the larger species, a Rhinoceros, the Indian Tapir, a very different species of Bos and of Moschus, an Antelope, the Argus, Polyplectron, several very peculiar species of Hornbill, (e.g. Buceros bicornis, and B. galeatus), and many other species and genera, which are not met with in Ceylon. It would be, however, anticipating the progress of science, when, as now, so small a quantity of incomplete materials are before us, to make comparisons between the Faunas of these countries, and it would be still more precipitate to attempt to draw general conclusions therefrom.

If we take into consideration at once the size of the laminæ of
