 Africa, p. 192, 1908. 



Typical locality Uniamwesi district, to tlie south of the 

 Victoria Nyanza ; the range also extending into Masailand. 



Type in the collection of Dr. 0. Neumann. 



Described as being closely related to M. kirhl hindei, but 

 distinguished by the more uniformly rufous tawny of the 

 whole of the upper-parts ; only the middle line of the back 

 being dark rufous in the latter, while the sides are olive or 

 fulvous. Hairs of back ringed near tips with red and black ; 

 but the black disappearing on the sides, so that hairs of 

 shoulders and flanks are wholly rufous ; head also uniformly 

 rufous, except on occiput, where black-tipped hairs make 

 their appearance. 



Of this duiker, which may be only a race of Jdrki, there 

 are no specimens in the collection.
