Equatorial Kob 
Adenota kob 
The equatorial kob is characterized chiefly by its black- 
fronted or striped legs, and by its uniformity in body size 
and shape of horns. The female is very little inferior in 
size to the male. In some of the races it shows great indi¬ 
vidual and age color differences in the male sex in the color 
of the ears, which assume a white coloration as age advances. 
In one race the male often becomes quite a deep brown or 
black on the upper parts. The color of the female is, how¬ 
ever, quite constant in the various races. The nursing 
young have the general color pattern of their female parent, 
but are slightly lighter, the dorsal surface and head being 
ochraceous. They particularly resemble the female in the 
possession of dark, seal-brown ear tips and in the restricted 
white orbital area, but the legs are without the dark stripes 
in front, these being merely indicated by a slight darkening. 
The light hoof-bands are also but faintly indicated. 
The range includes equatorial Africa from Senegal and 
the Niger eastward to the Nile Valley and the Victoria 
Nyanza, and northward to the edge of the Sahara Desert.
