THE DUIKERS 
Several other species of small, dark-coloured duikers more or less 
nearly related to the typical blue buck, and all of them practically identical 
with it in their habits and mode of life, are met with in various parts of 
Central and Western African, such as the Uganda duiker ( Cephalophus 
cequatorialis) of Uganda, the black-rumped duiker (C. melanorheus ), whose 
habitat extends from West Africa, south of the Niger to East Africa 
opposite Zanzibar; Maxwell’s duiker (C. maxwelli ), which ranges from 
Gambia to the Gold Coast; and the Urori blue duiker (C. lugens ), which 
is a native of Urori, British East Africa. 
In addition to all the above-mentioned species and races of the duiker 
family of antelopes, a small dark-coloured duiker, standing about eighteen 
inches at the shoulder, is found in the mountain forests of the hinterlands 
of Liberia and the Gold Coast, to which the name of black duiker (C. 
niger) has been given. In this species the horns are longer than in any of 
the species of the small red or blue bush -duikers, measuring in the males 
three or three and a half inches. Shorter horns are present in the female. 
To this species a small dark duiker recently discovered in Nyassaland, 
to which the name of Walker’s duiker (C. walkeri) has been given, may 
prove to be allied.
