The specimen has been mounted since this description was first pub- 
lished, and is in a much better condition for study than it then was. I 
find no necessity, however, to materially alter the description. The 
hairs of the frontal crest should be described as chestnut red, rather 
than bright chestnut. The forehead is dusky brown, like the body, 
rather than pale grey brown. like the face. 
The mounted skin was examined by Dr. Abbott while it was in the 
taxidermist’s shop, and several corrections of the shape were made at 
his suggestion. He pronounced it when finished as conveying a good 
idea of the species in life. 
The only species to which Abbott’s antelope appears to be closely re- 
lated is, as already stated, the Cephalophus niger of Gray. This was 
originally described in the Annals and Magazine of Natural History 
(18, 1846, pp. 165, 166). The description is as follows: 
Black Bush Buck, Cephalophus niger. Antelope niger, Mus. Leyden. 
Sooty black, grayer in the front half of the body; chin, throat, abdomen, and 
inside of thighs, gray; forehead, crown dark bay and black mixed; cheeks pale 
brown and black varied; tail end whitish. 
Inhab. Guinea. 
In the British Museum there is a male from the Leyden Museum nearly as large as 
the former. There is at Knowsley, a bush buck which is now shiny black with a 
reddish brown crest; when young it was red on the sides; it is perhaps the same as 
the above.* 
In a general way this description is applicable to our specimen, but 
the latter cannot be called black: it is a dark brown. The abdomen 
and inside of thighs are also dark brown, not gray, as stated in Gray’s 
description. 
There is a spirited drawing of Gray’s C. niger in the “ Gleanings 
from the Knowsley Menagerie.” It probably represents the individual 
mentioned in the second paragraph of the deseription quoted above. 
There is much more light color on the posterior part of the fore leg 
description is varied, as follows: ‘‘ Hair of cheeks and neck very short, sooty black,”
