In Somaliland, Captain Swayne tells us, the Klipspringer is known to the natives as the “Alakud.” Here they live in the most rugged mountains, “poising themselves on the large boulders, and leaping from rock to rock.” Finally, in Abyssinia we come to the most northern limit of this Antelope. The great explorer Rüppell was the first to meet with it in the rocky mountains of this country, and states that his specimens were undoubtedly identical with the Cape form, although attempts were subsequently made to separate the Abyssinian form under the barbarous name _Antilope saltatrixoides_. Heuglin also records the existence of the Klipspringer in the mountains of Abyssinia at elevations above 3000 feet. Mr. W. T. Blanford, F.R.S., who accompanied the Abyssinian Expedition of 1867–68, gives us the following particulars of this species:--“The Klipspringer is common on the more rocky of the Abyssinian hills, from a height of about 3000 feet above the sea, or rather less, to 8000 or 9000. In the pass below Senafé, and in that leading from Ain to the Anseba, by the valley of the Lebka, these little Antelopes were frequently seen, and they were common on some of the rocky precipices on the flanks of the great valleys around Senafé, Guna-Guna, Fokada, &c., usually solitary or in pairs. When alarmed they frequently perch on the very highest rocks, their agility in leaping from crag to crag being remarkable.” In the Cape Colony it is said that the Klipspringer, when taken young, is easily tamed and makes a most sagacious pet; but it does not appear to live long in captivity, and Mr. Bryden tells us that they are most difficult and troublesome to rear. We are not aware that specimens of this Antelope have ever been brought alive to Europe. Our illustration of this species (Plate XXV.) has been taken by Mr. Smit from specimens in the British Museum. It represents an adult male in the foreground and a male and female together in the distance. Besides two mounted specimens from the Cape, the British Museum contains three skins and skulls of this Antelope from Mounts Milanji and Zomba in Nyasaland (_Whyte_), an immature skull from Somaliland (_Swayne_), and some skins and skulls from Abyssinia. _December, 1895._ GENUS II.
