On examining two skins of adult females of what we suppose to be the 
same Antelope, obtained by Capt. W. H. Williams in Uganda, and presented to 
the British Museum in April 1893, we do not find the character, assumed by 
Herr Matschie as distinctive of the species, to be quite constant. The bellies 
of the two specimens just referred to are scarcely darker than in West-African 
specimens of C. melanorheus. Moreover, two examples of the latter species 
from Cameroons, collected together, differ markedly in the coloration of their 
bellies. We should therefore not have been inclined to admit C. equatorialis 
as a distinct species were it not for the fact that the perfect skull of one of 
the specimens in the British Museum shows no traces of horns. This is also 
stated to be the case in two female specimens in the Berlin Museum upon 
which Herr Matschie established the species. In C. melanorheus, as already 
stated, the horns are always present in both sexes. Under these circum- 
stances it is better to keep C. equatorialis, provisionally at least, as distinct, 
until further information is obtained. 
Mr. Scott Elliot during his recent adventurous journey to Mount Ruwenzori 
obtained a single specimen (now in the British Museum) of this Duiker in 
Uganda, and has favoured us with the following note upon it :— 
“The Cephalophus of which I brought home the skin was obtained from 
some natives at Kampala, Uganda, in February 1894. It was a female. I 
believe it was found on the highlands bordering Lake Victoria Nyanza, at an 
elevation of from 3900 to 4100 feet.” 
August, 1895.
