CAVENDISHS DIK-DIK 193 



fulvous.^ The hairs of the back are ringed near the tips with red and 

 black ; but on the sides the black disappears, and the hairs on the 

 shoulders and flanks are wholly rufous. The head is also uniformly 

 rufous, although black -tipped hairs make their appearance on the 

 occiput. 



CAVENDISH'S DIK-DIK 



{Mndoqua \^Rhync]iotrngus\ cavendisJii) 



This species was described by Mr. O. Thomas in p. 278 of the 

 Zoological Society's Proceedings for 1898 on the evidence of the skull 

 of an immature male brought by Mr. H. S. H. Cavendish from, it is 

 believed, the neighbourhood of Lake Rudolf. In general characters 

 this skull comes very close to that of Madoqiia kirki, but indicates a 

 considerably larger animal — as large as, if not larger than, daviareiisis. 

 A skin believed to belong to the same individual is dark fawn in 

 colour — much darker than daniarensis — on the fore part of the back, 

 while posteriorly, by the disappearance of the tawny tinge, it becomes 

 more greyish, till on the sides of the rump it is quite ashy grey. The 

 shoulders, an ill-defined line along each flank, and the fronts of the 

 limbs are sandy ; while a tinge of dull fulvous suffuses the hairs of 

 the crest. 



Its wide geographical separation renders it improbable that the 

 Lake Rudolf dik-dik is identical with the Damara species. 



GUNTHER'S DIK-DIK 



{Aladoqua \_Rhync]iotragus\ guentJieri) 

 Sokaro Giissuli, SOMALI 



With G anther's dik-dik, of Central Somaliland, we come once more 

 to a thoroughly well-marked species, distinguished, among other 

 features, by the excessive development of the trunk. It was first 

 described by Mr. Thomas on p. 324 of the Proceedings of the 

 Zoological Society for 1894. 



Having the essential characters of kirki, this species is distinguished 

 by the greater length of the upper jaw of the skull, accompanied by 

 a corresponding shortness of the nose-bones, the tips of which are in 



1 The colours are named somewhat differently by Mr. Neumann as compared with 

 Mr. Thomas.
