PETERS'S ORIBI 



(Oribia Jiastatd] 

 Insa, MANGANJA 



This, the Mozambique and Nyasaland representative of the oribi, 

 differs from the latter merely by the larger size of the bare ear-patch 

 below the ear, and the more slender and less heavily tufted tail, which 

 has a variable amount of white on the edges of its under surface. 

 Such slight differences indicate that the present animal, like its 

 Abyssinian relative, might well be regarded in the light of a local race 

 of the typical oribi, rather than a distinct species. A male shot by 

 Mr. Percy Kendall measured 21^ inches at the shoulder, and weighed 

 35 Ib. ; the corresponding items in the case of a female being 21 

 inches and 33 Ib. The presence of a glandular pouch between the 

 hoofs is noticed by the same sportsman, who also states that these 

 oribi are always found in the open, where they spring up out of the 

 long grass when disturbed in the same fashion as a steinbok. 



To the west this oribi ranges into Barotseland and Mashonaland. 



THE GAMBIAN ORIBI 



{Oribia nigricaudatii] 

 Gebari, GAMMA 



The western representative of the group comes very close to the 

 next species, but is of rather smaller size (2 I inches at the shoulder), 

 and has the large ear-patch of Jiastata, while it is further distinguished 

 by its greyer colour, and the presence of a distinct black tail-tip, like 

 that of the Cape species. The top of the muzzle is brown, and the 

 length of the ear 3.4 inches. 



The open districts of the Gambia and Senegal are the home of 

 this oribi, of which the habits are doubtless similar in all essential 

 points to those of other representatives of the group.
