ANTELOPES 299 



place, in September of the previous year, I saw a herd of some 

 thirty or forty beasts, every one of which was a buck ; but I do 

 not think that this can be taken as evidence that the bucks and 

 does separate at certain seasons of the year, as on the same 

 days on which I saw these two herds I also saw others in which 

 the bucks and does were together. A Thomsoni is a confiding 

 little beast, and, except in places close to a well-beaten 

 caravan route, where it has been constantly shot at, can be 

 easily approached within 120 yards with ordinary care and 

 perseverance, even in the most open and covertless places. 

 These beasts appear to be confined almost entirely to the 

 Masai country, as I have not heard of their having been seen 

 east of the Sigarari plains to the south of Kilimanjaro, or 

 south of the Useri river and the head-waters of the Tsavo. 

 I saw none at Njemps near Lake Baringo, or in Turkwel and 

 Ngaboto in the Suk country, though G. Grantii was plentiful in 

 all these places. 



PETERS' GAZELLE 



Gazella Petersi (known to the Swahilis also as ' Sala ') 

 may be a local variety of G, Grantii rather than a distinct 

 species. It used to be plentiful at Merereni on the coast, and 

 is still found further inland in the Galla country. It is cer- 

 tainly a smaller beast than G. Grantii from Kilimanjaro or 

 Machako's, but in other respects is almost identical, excepting 

 in the shape and size of the horns, which I have never known 

 to exceed 22 ins. in length measured along the curve. Their 

 horns are also straighter, and have not nearly such a pronounced 

 backward curve as those of the Grantii, neither do they diverge 

 towards the points so much, being rarely more than seven or 

 eight inches apart at the widest parts. G. Petersi is found in 

 the small open plains and open scrub. 



ABYSSINIAN ORIBI 



The Abyssinian Oribi (Swahili, 'Taya')is, I believe, not found 

 to the south of Upper Kavirondo. Between the river Nzoia
