The Rhinocerotes of Asia and Africa are known by the conforma- 

 tion of their jaws. The African species are easily distinguished by 

 the form of the head and of their nose-horns. The species of Asia, 

 on the other hand, are very difficult to separate from each other by 

 any external character, and are only to be characterized by the form 

 of their skulls and the locality which they inhabit, each zoological 

 district having a peculiar species ; and very probably there are yet 

 species to be described, as the Rhinoceroses of China, of Beloochis- 

 tan, and other countries which have not been examined by zoologists. 



The British Museum contains a good series of preserved specimens 

 of this family, and a large series of skeletons, skuUs, and horns ; 

 and there is also a very rich collection of skulls from different loca- 

 lities in the Museum of the Eoyal CoUege of Surgeons, — the two 

 collections affording good materials for the revision of the species of 

 this group. I have to thank the Council of the College of Surgeons, 

 and Mr. Flower, the energetic Curator of their Museum, for their 

 kindness in allowing me to examine the skulls in their collection. 



In the British Museum there are specimens of five species, viz. 

 one iJ. unicornis and two B. javanicus from Asia, and four specimens 

 from Africa (viz. two S. bicornis, one S. simiis, and one if. Tceiiloa), 

 the three latter species being the animals that were collected and 

 preserved under the superintendence of Sir Andrew Smith. 



The Indian species (R. unicornis) has been ofteii figured from 

 life, amongst others by Dr. Parsons, in the 'Phil. Trans.' 1742, 

 1743, t. 1, 2 ; E. swmatranus by Mr. BeU from life in the ' Philoso- 

 phical Transactions;' and if. javanicMS, by Dr. Horsfield ; and the 

 two latter also by Solomon M iiller, in his ' Verhandlung,' who gives 

 good figures of the adult and young. 



Three A-frican species have been well figured by Dr. Andrew 

 Smith, in his ' Illustrations of the animals of South Africa,' and two 

 of them by Capt. ComwaUis Harris, in his ' Portraits of the Wild 

 Animals of South Africa,' t. 16 & 19 ; so that the external appear- 

 ances of these animals are well known. 



The osteology of the species has been well represented by Camper, 

 by PaUas (in ' Nov. Com. Petrop.' 1777), by Cuvier (in the second 

 volume of his ' Ossemens Fossiles '), and fiirther illustrated in De 

 BlainviUe's valuable ' Ostdographie.' 



In the British Museum there are three skeletons and ten skuUs 

 of the Asiatic species, and a sheleton and four skuUs of the African 

 Rhinocerotes. 



The osteological collection in the British Museum is quite a 

 modern creation, and has been made under great diflaculties and with
