Hab. Uganda. 
The representative of the Black-rumped Duiker in Uganda has recently 
been separated by Herr Matschie from C. melanorheus under the name of 
C. equatorialis on account of its darker belly, which is stated to be of a bright 
isabella-brown colour, “ nearly of the tint which Mr. Ridgway, in his ‘ No- 
menclature of Colours’ (tab. iii. no. 21), calls écru drab, and scarcely lighter 
in colour than the back.” ‘The species was based upon five specimens 
obtained by Stuhlmann in Chagwe, Uganda, in the month of December. 
Dr. Stuhlmann’s note is that this Antelope lives in the forests of Uganda, 
and that its skins are brought in numbers to the market at Mengo. A living 
example of this species, we are informed by Herr Matschie, was in 1892 in 
the Zoological Garden of Berlin.
