“ 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. ”
