Under Cobus, the proper Latin form of Sir Andrew Smith’s term Kobus 
(taken, no doubt, from the so-called ‘‘ Kob” Antelope), we follow Flower and 
Lydekker in uniting the genera Cobus, Adenota, and Hydrotragus of some 
authors. 
The group thus formed contains 11 species which may be arranged in two 
sections as follows :— 
Section I. (Cobus). 
Larger in size ; fur grizzled; neck maned. 
A. Nape uniform with back; horns lunate, inclined forwards.

4. Without a white rump-band. 
a’. Kars shorter, rounded ; eye-region not white.
