“The long-necked ‘Gerenook’ is a bush-feeder, like the Giraffe, and is built on the same lines, except that the males carry curved horns. The body is on the scale of a small Fallow-deer, but such is its length of leg and neck that the head, when the animal is on guard, is held over six feet from the ground. They are generally found in small families of three or four. The bright chestnut back makes it fairly easy to see them even among the bushes. On the other hand, its sharp sight and length of neck give it a conspicuous advantage against pursuers. At the first sign of danger the Gerenook slinks behind the bushes, and peeps over the tops as from a small watch-tower. Imagine the strategical advantage you would have in guerilla-warfare if you could screw your head on to your umbrella and gently elevate it till it looked over the parapet, especially if your eyes were placed quite at the top. If they think themselves followed, down go their heads nearly to the ground and they retreat at a slouching trot, keeping completely out of sight. If you can manage to catch sight of one of these animals before he sees you, and that is seldom, do not shoot him, but watch him feeding. You will not have such a chance at the Zoo, for this species has never been brought alive to Europe. When he has consumed what he can reach in a normal attitude he rears up and stands on his hind legs, assuming a perfectly erect position. With the fore feet, which are carried level with the cheeks, he holds the boughs down, and assists his balance. If he happens to be facing you, so as to show his white belly, the appearance is particularly odd, being that of a tall brown man clad in a white apron.” It will be recollected that _Lithocranius walleri_, although actually better known to us from Somaliland, was originally discovered in the southern part of its range, in British East Africa. Here, according to Mr. Hunter, it is “very rare in the Kilimanjaro district, though numerous up the Tana River.” Lieut v. Höhnel, who accompanied Count Teleki’s expedition to Lake Rudolph, informs us that it is common also on the Upper Tana, between Hameye and the mouth of the Mackenzie River, but that none were found on the Guaso Nyiro. Mr. Jackson, in the first volume of ‘Big Game Shooting,’ writes as follows concerning the habits of this species in British East Africa:--
