Summary

Hermann Schlegel Natural History Review: a quarterly journal of biological science (1862)

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.

Hence it appears vey clear that Cuvier described his Elephas indicus from specimens of two different species, one of which agrees with the Elephant of Bengal, whilst the others have all the characters of the Elephant of Sumatra. Since, therefore, both the latter skeletons attributed by Cuvier to Ceylon, presented the characters of the Elephant of Sumatra, it appeared to me to be probable that the Ceylonese Elephant belonged to the Sumatran species, and not to that of Bengal—the so-called Elephas indicus.
