476 ABBOTT’S KILIMA-NJARO MAMMALS —TRUE. 
than in Abbott’s antelope. The tail is represented as slender, with a 
large white tuft at the end, and apparently as being white underneath, 
In Abbott’s antelope the tail is equally broad throughout and is dark 
brown on both sides, with only a few white hairs at the tip. 
Jonsidering the common inaccuracy of descriptions, it is posite 
I presume, that the two species may be identical, but until a detailed 
description of C. niger, with measurements of the exterior and skulls, _ 
has been published, the question must remain open. i 
48965 Male, adult. Mount Kilima-Njaro. Type. 
Cephalophus nigrifrons Gray. Black-fronted antelope. 
The collection contains a single male from Taveta. Gray’s figure* 
of the species is in some respects inadequate, and in others does not 
agree exactly with the specimen under consideration. The size is not 
indicated. Compared with the figure, our specimen has shorter and 
thicker compressed horns. The horns are stout at the base and dimin- 
ish abruptly from about the middle toward the tip. The muzzle is 
entirely dusky brown, not rufous, with a median dark band, as repre- 
sented in the figure. The broad black frontal band continues with 
undiminished breadth to the base of the horns, and the slight crest 
between the horns, as well as the median line of the nape, are black. 
The fore legs, within and without, are entirely dusky, not rufous above 
the knee, as represented in the figure. 
The specimen, as mounted, gives the following dimensions:
