shot one of the former in mistake for the latter. The habits and 

 gait are much the same, save that the Dibatag trots off with 

 head held up, and the long tail held erect over the back like 

 a stick, nearly meeting the head, while Waller's Gazelle trots away 

 with its head down and its short tail screwed round. Like 

 Waller's Gazelle, the Dibatag goes singly or in pairs, or small 

 families up to half a dozen or so. 



Like Waller's Gazelle also, the Dibatag is enabled by its long- 

 neck and long upper lip to reach down branches of the mimosa 

 bushes from a considerable height. As I have mentioned before, 

 the shape of head and way of feeding of both the Dibatag and 

 Lithocranius walleri are giraffe-like, and I have seen both animals 

 standing on the hind legs, fore feet planted against the trunk of a 

 tree, when feeding. I think Waller's Gazelle subsists almost 

 entirely on bushes, as they are constantly found in places deserted 

 by Oryx and all other antelopes because there was no grass. I 

 have seen Dibatag feeding both on thorn-bushes and on the 

 " durr " grass. Both antelopes can live far from water. 



The country most suitable for Dibatag is jungle of the " Khansa " 

 or umbrella mimosa alternating with glades of " durr " grass, 

 which grows about six feet high. The females are hornless. 



The Sakaro Antelopes (see P. Z. S. 1892, p. 307). T 



There are certainly two of these small Antelopes, which are 

 called by the natives " Sakaro Gussuli" or "Gussuli" and "Sakaro 

 Gol-ass" or " Gvl-ass" (i.e. red-belly). 



There is also a third Sakaro recognized by the Somalis, which I 

 have often shot and generally classed with the Gol-ass. It is smaller 

 than the Gol-ass and has yellowish grey on the sides of the belly 

 instead of red, but is in every other respect similar. The Somalis 

 call it " Sakaro Gayu " or " Grwyu" and declare it to be a distinct 

 variety from the Gol-ass, to be known by its smaller size and 

 the yellow bell} 7 . It appears to be found wherever the Gol-ass is 

 found. 



I have often noticed, in about two hundred specimens that I 

 have shot for food at one time or another during eight years, that 

 the skulls appear to vary much in size in adult animals, but my 

 attention was called to the third native name only at the end 

 of my last expedition. 



I will therefore consider, in the absence of proof, that there are 

 only two kinds of this small antelope, viz. the Gussuli and the 

 Gol-ass. 



The Gol-ass is the ordinary Somali " Sakdro" which I have 

 mentioned in my former paper. 



I came on the " Gussuli " for the first time a day's journey 

 south of Seyyid Mahommed's village in the Malingur tribe and all 

 over the Her Amaden country. Its range is very similar to that 

 of the Ehinoceros, and it is found in many parts of the Hand,
