LVIII. — Rhynchotragus daraarensis variani, subsp. n. 

 By R. E. Drake-Brockman, M.R.C.S., L.R.C.P., F.Z.S. 



I lately received from Mr. H. F. Varian, from Lobito, 

 Angola, Portuguese South-West Africa, a dik-dik which 

 differs somewhat from the typical R. damarensis, Giinther. 



The general colour of this dik-dik is brighter and richer 

 than that of the type-specimen, which was obtaiued nearlv 

 three degrees to the south, at Omaruru, in German East 

 Africa. In the present form the pale buffy cinnamon of the 

 flanks extends on to the chest and abdomen, and does not 

 fade to white as in the type. The grizzling of the back is 

 darker, as also are the bases of the long hairs of the back, 

 while the hairs themselves are shorter and more " stubbly " 

 than those in the type-specimen. 



The bases of the long hairs of the crest are considerably 

 darker than in R. damarensis. 



There is, unfortunately, no skull to the only other specimen 

 of this race in the British Museum, the immature specimen 

 presented by G. W. Penrice, which was shot on the Coporole 

 River, Angola ; so I propose to make Mr. Varian's care- 

 fully preserved specimen the type of this northern race, for 

 which I propose the name R. damarensis variani. 



There is little or no difference in the general coloration of 

 Penrice's immature specimen and Variants.
