In his ‘Neue Wirbelthiere,’ after a careful description of this Antelope, Rüppell tells us that it is only found in the mountainous provinces of Abyssinia, where the vegetation consists principally of bush, and in such parts of them as rise from five to eight thousand feet above the sea-level. Rüppell met with it first at Galla on the mountain-chain west of Massowa. Afterwards he found it common on the mountains and valleys of the “Kulla,” where it is always met with in pairs and is difficult to shoot on account of its traversing the bush so quickly. Its Abyssinian native name, Rüppell tells us, is “Madoqua,” which, however, as already stated, has likewise been applied to another species--Salt’s Antelope. The only more recent traveller, so far as we know, that has met with the Abyssinian Duiker in its native wilds is Dr. W. T. Blanford, F.R.S., who accompanied, as Naturalist, the British Abyssinian Expedition from Massowa to Magdala in 1867–68 and subsequently published an excellent volume containing the results of his observations on the geology and zoology of that country. Dr. Blanford tells us that this Bush-Antelope is not rare on the highlands of Abyssinia at elevations of from 7000 to 8000 feet. He usually saw it solitary in the bushes and small clearings and obtained two bucks, one at Dildi, the other at Dongolo, of which he gives us the dimensions. These specimens (as is recorded by Mr. W. L. Sclater in his ‘Catalogue’) are now in the India Museum, Calcutta. The British Museum contains a single adult male specimen of this species mounted (together with its skull), upon which Thomas based the name _abyssinicus_. Our figure of this species (Plate XXII. fig. 1) was prepared by Mr. Smit under the directions of the late Sir Victor Brooke, but from what specimen we are unable to say. _August, 1895._ [Illustration: THE BOOK OF ANTELOPES, PL.
