Hab. South Africa. 



I have not seen the skull of this species, and I do not believe there 

 is one in any European Museum. 



Camper probably knew R. oswellii. He observes, " Cornu ante- 

 rius A D in hoc specimene incurvum adeo fuit ut alterum E F H, 

 tamquam inutile reddiderit. Verum nou ita in omnibus ; possideo 

 alterius cranii partem, cujus cornu anterius rectum, et antrorsum 

 incliuatum est." — Camjier, I. c. 186. 



Mr. Baines gave a fcetus of the Kobaaba to the Royal College 

 of Surgeons (killed 3rd of June, 1862). He has shown me a series 

 of drawings of the recently killed Kobaaba. One group represents 

 the R. simus and R. oswellii side by side. The horns of the two 

 are verj' different in appearance. 



Mr. Baines says Mr. Chapman was informed by the natives that 

 they had never seen a young Kobaaba = R. oswellii. Mr. Baines 

 says that it is possible that the horn, being worn away at the end by 

 the constant friction on the front as it passes through the bushes, 

 may bend forward in the older specimens. The Kaffirs make the 

 horns of the cattle bend by scraping them on the sides towards 

 which they wish them to turn. 



Schinz gives the name of niyer to the Rhinoceros horn figured by 

 Andersson ; but he describes it as curved back, in the same words as 

 he described the horns of the other African species. 



Camper compares the labial process to a finger, and says it is not 

 unlike the lobe at the end of the trunk of the Elephant. 



See M. F. Fresnel's "Sur I'existence d'une espece unicorne de 

 Rhinoce'ros dans la partie tropicale de I'Afrique" (Comptes Rendus, 

 xxvi. 1848, p. 281). See also A. Smith's 'lUust. Zool. S. A.' t. 1, 

 where he says the natives mention a one- horned African species. 



IIL Skin smooth, even. Skull 1 Internasal bony, short ; the 



nasal, internasal, and the intermaxillaries tmited into one mass.

 nasal bones broad, rounded in front ; cutting-teeth none ; intermax- 

 illaries very short ; internasal bony, uniting the nasals, the inter- 

 maxillary, and maxillae into one mass. Asia, Europe, Africa.
