on the slopes of which it ranges to an altitude of 10,000 
feet. 
The Uganda race of the red duiker was named by 
Oldfield Thomas from a specimen collected in 1900 by Sir 
Harry Johnston in Toro during his administration as special 
commissioner of Uganda. The type unfortunately is quite 
youthful, having only the milk teeth in use and does not 
represent the adult coloration. Immature specimens of 
ignifer of the same age are quite like the type of johnstoni. 
Another species described by Thomas as rubidus , from a 
flat native skin without skull obtained in the same general 
region, is doubtless an adult of johnstoni and is much redder 
than the younger specimen, which is in the blackish pelage 
of youth. The Uganda red duiker may be known from the 
highland race by its larger body size and lighter or more 
tawny coloration, old adults being quite yellowish or 
ochraceous-tawny, similar to zveynsi of the upper Congo. 
In the young the head, neck, shoulders, and fore back are 
quite blackish or seal-brown with only the rump and the 
legs bright rufous. 
The heads of a male and a female from Kampala, pre¬ 
sented by District Commissioner Knowles to Colonel 
Roosevelt, are in the National Museum. The dimensions 
of these specimens are: length of skull, male, yyi inches; 
female, 7 inches; length of horns, male, 3^ inches; female, 
inches; diameter of horns at base, male, iys inches; 
female, inch.

Range.— Forests of Kilimanjaro and the Usambara 
Range. 
The type specimen collected by Doctor L. W. Abbott 
at a high elevation on Kilimanjaro has remained unique 
for many years. Recently, the British Museum has re¬ 
ceived a head from the Usambara Range, at a point one 
hundred miles inland from Tanga, a port on the coast of 
German East Africa. This discovery would indicate that 
the species is not confined to the high forests of Kilimanjaro, 
but is distributed throughout the coast forests as well.
