THROUGH SOMALILAND AND ABYSSINIA chap. 
As is the case with Waller’s gazelle, the Bibatag is enabled 
by its long neck and rather long upper lip to reach down 
branches of the mirndsa bushes from a considerable height. 
The shape of head and way of feeding of both antelopes are 
giraffe-like, and I have seen both standing on the hind-legs, with 
the fore-feet planted against the trunk of a tree, when feeding. 
I have seen Dihatag feeding both on thorn-bushes and on the 
durr grass. Both Waller’s and Clarke’s gazelles can live far 
from water. The country most suitable for Bibatag 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 Bibatag is a graceful antelope, standing higher 
than an Indian blackbuck, but weighing probably a good deal 
less. 
Waller’s Gazelle ( Lithocranius w oiler i) 
Native name, Gerenuk 
The Gerenuk is the commonest and most widely distributed 
of the Somdli antelopes except the little Sakaro , which springs 
like a hare from every thicket. 
The long neck of the Gerenuk , large giraffe-like eyes, and 
long muzzle, are peculiar to this species and the Bibatag. The 
Gerenuk is more of a browser of bushes than a grass-feeder, and 
I have twice shot it in the act of standing on the hind -legs, 
neck extended, and fore-feet against the trunk of a tree, reaching 
down the tender shoots, which could not be got in any other 
way. Thus not only the appearance, but the habits of the 
Gerenuk are giraffe-like. The skul] extends far back behind 
the ears like that of a camel. 
It is found all over the Somali country in small families, 
never in large herds, and generally in scattered bush, ravines, 
and rocky ground. I think it subsists almost entirely on bushes, 
as it is constantly found in places deserted by beisa and all 
other antelopes because there was no grass. Perhaps the Gada- 
bursi country is the best ground, but the Gerenuk is almost 
ubiquitous and need not be specially looked for. I have never 
seen it in the cedar-forests which crown G6Jis, nor in the tree- 
less plains of the Haud. It is not necessarily found near water, 
— in fact, generally on stony ground with a sprinkling of thorn 
jungle.
