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 riibidus, 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 zueynsi 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, 

 i^ inches; diameter of horns at base, male, i^/i 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.
