_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 certainly 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.
The Abyssinian Oribi (Swahili, ‘Taya’) is, I believe, not found to the south of Upper Kavirondo. Between the river Nzoia and the base of Mount Elgon it is fairly plentiful, as also in Turkwel. In habits it differs from its East African congener in one respect only, not appearing to be so partial to long grass, but being confined more to rough stony ground and short scrubby bush. This gives the sportsman a chance of seeing it at a distance, and an opportunity of stalking it which the oribi of the coast very rarely affords, unless the grass in which they usually lie has lately been burnt.
The East African Oribi (also known to the Swahilis as ‘Taya’) I have found more plentiful on the mainland near Lamu than anywhere else. Sir Robert Harvey and Mr. Hunter, in October and November 1888, also found it in fair numbers up the Tana river. I have never seen it myself south of the Sabaki, though doubtless it is to be met in suitable places. At Merereni where the country seems admirably suited to its habits, although I was shooting there for some time in 1885 and 1886, I never saw one, though some fifteen miles further south, near Mambrui, I observed its spoor. This confirmed me in my theory that the oribi is very partial to the vicinity of cultivated tracts, and I do not remember having seen one in an uninhabited district. At Taka, a small village on the mainland opposite Patta island, I saw great numbers in 1885.
