OTHER DIK-DIKS 



In the Ann. Mag. Nat. Hist, for 1909 (sen 8, vol. iv. p. 49) Dr. 

 Drake-Brockman described a new race of Phillips's dik-dik from the 

 Guban district of Somaliland, as Madoqua phillipsi gubanensis, and a 

 new species from Abyssinia as AI. cordeauxi. The former differs from 

 the typical representative of the species by its thinner and shorter 

 hairs, which give to the coat a sleeker appearance. The Harar dik- 

 dik {snpj'a, p. 190) is relegated by Dr. Brockman {Proc. Zool. Soc. 

 191 1, p. 979) to a race of //!////)^j/ characterised by its darker colour 

 and thicker coat ; it inhabits high ground. The name M. placentinii 

 has been given by the same writer {Proc. Zool. Soc. 1911, p. 981) to a 

 Somali dik-dik allied to siuaynei, but distinguished by the much 

 greater development of the grizzling of the hairs, so that the whole of 

 the upper-parts, with the exception of a clay-red nose-patch and the 

 crest, appears grey ; the buff ears have black margins. 



Cordeaux's dik-dik, on page 983 of the journal last cited, is 

 referred by its describer to Rhynchotragus. Having the distinctive 

 head-characters of that group, it much resembles M. phillipsi gubancnsis 

 in general appearance, but is considerably larger. 



Yet another local race, M. [7?.] guentheri wroughtoni, from the north 

 bank of the Wabi River, in the foot-hills of Mt. Abu-el-Kassim — far 

 away from the typical locality of the species — has been described by 

 Dr. Brockman {Ann. Mag. Nat. Hist. op. cit. p. 5 i). It is specially 

 distinguished by its larger ears and darker colour. Lastly, M. erlangcfi 

 {snpra, p. 190) is referred by Dr. Brockman {P.Z.S. 191 i, p. 983) to 

 Rhynchotragus.
