It was not to be expected that any representative of the Oribi would be 
found in Congoland or within the great forest-clad region of Western 
Africa. But when we come to the more open country of Senegal and the 
Gambia, an allied and nearly similar species appears upon the scene. The 
first evidence of its existence was given by F. Cuvier in 1829 by the publi- 
cation of a figure and description of a female specimen under the name of 
the “‘ Ourebi du Sénégal,” which was brought home alive by M. Perrotet, but 
died shortly after its arrival at Paris.
