well fitted for it, the Gemsbuck is unknown. “So far as my experience goes, the Gemsbuck is far from being the fleetest or most enduring Antelope in South Africa, and in these respects cannot be compared to the Tsessebe or Hartebeest. I do not think it is either fleeter or more enduring than the Sable or Roan Antelope; and I have myself run one to a standstill without firing a shot, and I know of several other men having done the same thing. The horns of the cow become longer than those of the bull, as a rule; the longest pair of the former I have ever seen measured 3 feet 10½ inches, and of the latter 3 feet 6 inches,” Mr. H. A. Bryden, writing in 1889, describes the Gemsbok as then “very nearly extinct in the Cape Colony.” Seven or eight years previously two of the last had been shot in the north of Calvinia, near the banks of the Orange River. Mr. W. L. Sclater, Director of the South African Museum, Cape Town, writing of the present distribution of the Gemsbok in South Africa, informs us that, according to the statistics of the Agricultural Department, there are about 5000 Gemsboks still existing in Bechuanaland between Namaqualand and Kenhart. There are also said to be plenty of these Antelopes still to be found throughout the German South-west African territory and the western part of the Kalahari Desert. North of German South-west Africa, we know from Capello and Ivens, and other Portuguese authorities, that the Gemsbok is also found in Mossamedes and in the adjoining arid districts of Southern Angola. The Gemsbok is very rarely seen in captivity, and we are not aware that living examples of it have ever been brought to Europe. Mr. Carl Hagenbeck, of Hamburg, who has had great experience in such matters, informs us that he has never seen this animal alive. There is a fine mounted pair of the Gemsbok in the Gallery of the British Museum, obtained by Mr. F. C. Selous in the Bamangwato District of Bechuanaland, and a frontlet and horns procured by the same enterprising hunter on the Botletli River. Besides these there are several older stuffed specimens, as also some heads and skins, of which the exact localities are unknown. Our figure of the Gemsbok (Plate LXXXIII.) was drawn on the stone by Mr. Smit from Mr. Wolf’s sketch, but it is, unfortunately, impossible to ascertain from what specimen it was taken. _May_, 1899.
