Rhodesia, Angola, and Northern Nigeria. 131 



Major C. H. B. Grant has now kindly presented three topo- 

 typical examples, two males and a female, collected by him 

 in the Lindi District in July 1919. On comparing these 

 with the specimens from the Chinsali District, the latter are 

 immediately seen to differ by their richer and deeper colora- 

 tion. The Ilhodesian animal may therefore be described as 



Oreotragus oreotragus centralis, subsp. n. 



Like 0. 0. aceratos, but general colour of upper parts 

 deeper and richer. 



Upper surface of head, neck, and back bright, deep 

 ochraceous in general colour, the tint differing from that seen 

 in the corresponding parts of aceratos to the extent of the 

 difference between tlie "ochraceous buff" and the "raw- 

 sienna " of Ridgway ; the colour is most intense upon the 

 nape and over the shoulders. Rump, in some specimens, 

 grey, like the outer parts of the thighs, in others more or less 

 invaded by the ochraceous tint of the fore parts. No white 

 pieorbital patches upon the face (these being conspicuous in 

 aceratos). Upper surface of muzzle dusky ; top of head 

 between and in front of ears irregularly blackened. Ears as 

 in aceratos, but the white patch on each proectote smaller. 

 Under surface white, save for the broad ochraceous collar. 

 Dorsal surfaces of limbs grey, somewhat darker than in 

 aceratos ; the dusky hoof-patches slightly more extensive. 



Skull not peculiar; females hornless. 



Type. An adult male. B.M. no. 7. 11. 15. G. Collected 

 in the South Chinsali District and presented to the British 

 Museum by Mr. R. L. Harger. 



llah. North-east Rhodesia. 



Unfortunately none of the four specimens from the type- 

 locality is dated. The examples in the collection from 

 Zomba and the Mlanje Mountains are intermediate between 

 aceratos -Awd. centralis ; in general colour they approach the 

 former, but in the characters of the face and ears they moie 

 nearly resemble centralis. Possibly these two subspecits 

 intergrade in the country to the south of Lake Nyasa. 



On the west coast, in Angola, another subspecies, appa- 

 rently allied to aceratos, has been discovered. This niay 1, e 

 described as 



Oreotragus oreotragus iyleri, subsp. n. 



Alight-coloured representative of 0. o. aceratos; without 

 dark hoof-patches.
