SEI^BORNE ROOr HARTEBEEST. 



AlCELAPHUS CAAMA SELBOElfEI. 



Biibalis caama aelbwnei, Lydekker, Proc. Zool. Soc. 1913, p. 820, fig. 135, 

 Abstract No. 119, p. 19. 



Closely related to the extinct Cape Eooi Hartebeest, the typical 

 race, which appears to have been confined to the area south of the 

 Orange River. The present race was founded on a specimen from 

 Kimberley, imported from the Transvaal ; it is said to differ from 

 caama in being paler in colour, and in having the dark face blaze 

 mixed with tawny and not extending to the horns and muzzle. 

 The light marking between the eyes is also more extensive, and 

 the dark markings on the limbs are less developed and less intense. 

 Distinguished from the Lelwel Hartebeest by the dark face blaze, 

 light marking between eyes, dark. markings on limbs, and light 

 coloured rump. The horns, mounted on a high pedicle, curve 

 forwards above the V and then turn sharply backwards, almost at 

 right angles ; they are about equal in length to those of jacksoni, 

 good horns from 24 to 26 inches in length along the fi-ont curve. 



Best horn measurements (No. 19. 7. 15. 84) : — length on front 

 curve 23^ ; circumference 12 ; spread from tip to tip 10|. 



This race extends northwards from the Orange River into 

 Southern Rhodesia and Bechuanaland. 



Selous * gives the following account of the distribution of the 

 Rooi Hartebeest : — " The range of this Antelope is very similar to 

 that of the Gemsbuck. It is still found in Griqualand West, in 

 some parts being fairly plentiful. All along the eastern border of 

 the Kalahari Desert it is also to be found, and extends as far east 

 as the river Serule on the road from Bamangwato to Tati. In 

 the neighbourhood of the saltpans lying between the Botletlie 

 River and the road from Bamangwato to the Zambesi, it is very 

 plentiful, and may be met with in large herds. It does not, 

 however, extend its range to the north of these saltpans, and is 

 unknown in all the country between the Chobe and Mababe rivers, 

 as it is also in the Matabele and Mashuna countries "
