DAMARA DIK-DIK 191 



it has full claim to specific distinction. In colour it approximates to 

 saltiana, but in size it is inferior to phillipsi, and therefore still smaller 

 than saltiana. The back is grey with a strong suffusion of yellow 

 or fulvous ; the limbs are rufous, and the flanks faintly rufous, so as 

 to differ markedly from the full well-defined rufous of the sides of the 

 body in phillipsi. The bucks weigh but 6 lb. and the does even less. 



This dik-dik, which takes its name from Colonel H. G. C. Swayne, 

 is, like its kindred, extremely fleet, although the Somalis are able to 

 run down very young fawns. It feeds on the young shoots of mimosa, 

 and is partial to the neighbourhood of water, drinking, it is said, 

 at mid-day and again at evening. These dik-diks lie very close, 

 and when put up dash off with two or three whistling notes, 

 which are only too apt to alarm the larger game in their immediate 

 neighbourhood. 



Colonel Swayne states that the gol ass {i.e. " red belly ") is the 

 ordinary dik-dik found all over Cuban and Ogo and in parts of the 

 Haud and Ogaden. The guyu differs in being very much smaller, with 

 the flanks yellowish grey instead of reddish yellow. Both occur in the 

 same districts. 



THE DAMARA DIK-DIK 



{Madogiia \_RJiyiichotragns'\ daiiiare?tsis) 



With this species we come to the second group of the genus, 

 separated in 1905 by Mr. Oscar Neumann in the paper cited above 

 generically as Rhytichotragics. The most important features of the 

 group are the greater development of the trunk, as compared with 

 the typical group, and the presence of the normal three lobes in the 

 last lower molar teeth ; other characters being mentioned under the 

 heading of Salt's dik-dik. 



Agreeing with the next species in the circumstance that the tip 

 of the nose- bones of the skull is approximately on the line of the 

 front border of the foremost pair of cheek-teeth, this dik-dik, which 

 was described by Dr. A. Giinther in the Zoological Society's Proceedings 

 for 1880, is distinguished by its superior size, in which respect it 

 appears, indeed, to exceed all other members of the genus except 

 Madoqua cavendisJii. A native of Damaraland, it doubtless has the 

 habits common to dik-diks generally. 



The range of the species is definitely known to extend from 

 Omaruru, about 60 miles north of Walfisch Bay, to Benguela.
