1867.] DR. J. E, GRAY 0^ THE RHINOCEROTIDjE. 1005 



The Museum of the College of Surgeons contains two skeletons 

 and thirteen skulls of the Asiatic and three skulls of the African 

 Rhinocerotes. One of these skulls is very interesting ; it belongs to 

 the one-horned Indian group, and is much like that of R. unicornis 

 in general characters. It is an adult skull, with all the permanent 

 teeth ; and it is so much smaller than the skull of the adult or even 

 a half-grown animal of that species, that it indicates an animal not 

 more than half, or perhaps one-third, of the size of the common 

 Indian Rhinoceros. 



There are generally one or more skulls of the animals of the genus 

 to be seen in the larger local museums, as, for example, at Man- 

 chester, Leeds, and York. If these skulls could be collected together 

 and compared, they would form a most interesting collection for 

 study ; unfortunately they are generally without any certain history 

 as to habitat &c. 



Cuvier, in his essay above quoted, has given an excellent resume 

 of the history of the former knowledge of the animals ; and I have 

 only to observe that he did not discover that the skull figured by 

 Cam])er, which he copied (t. 2. f. 7) and regarded as the skull of 

 the adult Rhinoceros bicornis, is the skull of the Rhinoceros Jceitloa. 

 He mentions R. simus as a distinct species, from M. de Blainville's 

 note on the animal (from Mr. Burchell's MS.) in the 'Journal de 

 Physique.' 



The horns of these animals attracted the attention of Dr. Parsons, 

 who figured several of them in a paper in the ' Philoso})hical Trans- 

 actions ' for 1742 and 1743, among the rest the horns of some Afri- 

 can species, which have, since Cuvier's time, been determined, chiefly 

 by the form of the horn, to be distinct species. Some of these 

 horns are still in the British Museum.

 African species.
