In the British Museum there is the skull of a nearly adult animal. 



In the Museum of the Eoyal CoUege of Surgeons is a very fine 

 skull of an adult of this species (no. 2941), and the upper jaw 

 covered with skin (no. 2942) and with the two horns attached to 

 it. The horns are both circular at the base, regular conical, and 

 blunt at the tip. 



Schinz, who compiled a monograph of the genus, in his Synopsis 

 named a species R. niger, after Capt. Alexander's description of the 

 Black Rhinoceros in his ' Travels into the Interior of South Africa.'
