specimen as far as the mane, but in other examples being mainly 

 confined to the rump. In one skin there is distinct brindling on the 

 neck, but elsewhere both dark and light areas are almost free from 

 bands, although a few indistinct bars occur on the sides of the chest in 

 one skin. Other specimens show a gradual increase in the number 

 and distinctness of the barrings, accompanied by a lightening of the 

 colour of the coat, so that there seems to be practically a transition 

 to the light-coloured and brindled Kilimanjaro gnu. 



THE DUIKERBOK 

 (Page 141) 



The more typical long-eared representatives of the species are 

 found all over South Africa ; the most northern form of these on 

 the west being CepJialophus grimmi splendidulus, Gray, from Angola ; 

 farther east is the Matabili C. g. flavescens, Lorenz, which probably 

 crosses the Zambesi into northern Rhodesia ; the eastern representative 

 is C. g. altifrons, Peters ( = ocularis, Pet.) from southern Mozambique, 

 which ranges south of the Zambesi to Tette and north to the Loangwa 

 river, at least as far south as Angoniland. In the Shire Highlands 

 Mr. R. C. Wroughton has shown (Annals and Magazine of Natural 

 History for 1910, series 8, vol. v. page 274,) that these long-eared 

 races give place to short-eared types allied to the Abyssinian duikerbok, 

 which is often reckoned as a species, but which may be regarded as a 

 race of the southern one, under the name of C. g. abyssinicus. The 

 Shire race, which on this view will be known as C. g. shirensis^ agrees 

 in size with the other East African forms, but is distinguished by its 

 brighter ochery coat, the general colour above being ochery buff; all 

 the hairs have drab bases, those of the neck and shoulders are ochery 

 buff to their tips, those of the back shortly tipped with black. Below 

 the colour is the same as in the next race, but much paler. 



The second race described by Mr. Wroughton, C. g. hindei, is from 

 Nyasaland and characterised by its bright colouring. In size it is 

 about the same as C. g. nyansae ; its general colour above being tawny 

 ochre, bright on the neck and shoulders, duller on the back and loins, 

 but the yellow tinge is never absent, even on the rump, as it is in 

 nyansae ; individual hairs of the neck are drab-grey, with ochery tips, 

 but posteriorly the ochery tip becomes a sub-apical ring and the tip 

 black. The chin and insides of the upper part of the limbs are
