“The long neck of the _Gerenúk_, the large giraffe-like eyes, and long muzzle are peculiar to it and the _Dibatag_ (_Ammodorcas clarkei_). The _Gerenúk_ 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 _Gerenúk_ are giraffe-like. The skull 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 Oryx and all other Antelopes because there is no grass. Perhaps the Gadabursi country is the best ground for it, but the _Gerenúk_ is almost ubiquitous and need not be specially looked for. I have never seen it in the cedar-forests which crown Gólis, nor in the treeless plains which occur in the Haud. It is not necessarily found near water,--in fact, it is generally met with on stony ground, where there is a sprinkling of thorn-jungle. “The gait of this Antelope is peculiar, and when first seen a buck will generally be standing motionless, head well up, looking at the intruder, and trusting to its invisibility. Then the head dives under the bushes, and the animal goes off at a long crouching trot, stopping now and again behind some bush to gaze. It seldom gallops, and its pace is never very fast. In the whole shape of the head and neck, with its extended muzzle and slender lower jaw, there is a marked resemblance between the _Gerenúk_ and the _Dibatag_. The texture of the coat is much alike in both. The horns of immature buck _Gerenúk_ have almost exactly the same shape as those of the _Dibatag_. Their average length when fully grown is about 13 inches. The females are hornless; they sometimes lose or desert their young ones, as I have now and then come on fawns living alone in the jungle. The _Gerenúk_ stands a good deal higher than an Indian Blackbuck, but would be of about the same weight.” Mr. Frederick Gillett, F.Z.S., who accompanied Dr. Donaldson Smith during the first part of his expedition to Lake Rudolph, has kindly drawn up for us the following notes on Waller’s Gazelle:--
