Hab. India. 



The skull figured by Cuvier and by De Elainville for the skull of 

 R. unicornis, probably from the same skull in the Paris Museum, 

 has a broad bony process on the middle of tlie upper edge of the 

 intermaxillary bones. The skeleton and skull in the British Museum 

 (722(7), from an adult male specimen that lived for several years in 

 the Zoological Gardens, has this bony process well marked ; so that 

 it seems common in the species, if not a peculiar character of it. 



Mr. Blyth thinks that " the adult male Rhinoceros that lived in 

 the Zoological Gardens for several years, stated to have been captured 

 in Aralx-an, was R. sondaicus." He proceeds, " The two Asiatic one- 

 horned species, indeed, resemble each other a great deal more nearly 

 in external appearance than the pnbhshed figures of them would 

 lead to suppose ; certainly no sportsman or ordinary observer would 

 distinguish them apart, unless attention had been specially called to 

 the subject." — Joiirn. Asiatic Soc. Bengal, xxxi. 1862, p. 132. This 

 explains how the species, now described for the first time, may have 

 been overlooked. 



In the British Museum there is the skeleton (722 g) with the skull 

 of an adult animal that hved for several years in the Zoological Gar- 

 dens, referred to by Mr. Blyth, and a skull from a just born animal, 

 which was presented by Mr. Bryan Hodgson from Nepal. 



There are in the British Museum other skuUs which have been 

 received from various persons without any special habitat that can 

 be relied on, which appear to belong to this species. The}' are 

 all without the process on the upper edge of the large thick inter- 

 maxillaiy bones.

2. An adult skull (722 f) that was purchased of a dealer, without 

 any specified locality.
