In 1881 the renowned hunter, Mr. F. C. Selous, in his “Field Notes on the Antelopes of Central South Africa,” read before the Zoological Society, described the present abode of the Hartebeest as follows:--“The range of this Antelope is very similar to that of the Gemsbuck. It is still found in Griqualand West, in some parts being fairly plentiful. All along the eastern border of the Kalahari desert it is also to be found, and extends as far east as the river Serule on the road from Bamangwato to Tati. In the neighbourhood of the salt-pans lying between the Botletlie river and the road from Bamangwato to the Zambesi it is very plentiful and may be met with in large herds. It does not, however, extend its range to the north of these salt-pans, and is unknown in all the country between the Chobe and Mababe rivers, as it is also in the Matabele and Mashuna countries. It is very fleet and enduring, and only second in these particulars to the Tsessebe.” Our figure of this species was lithographed on the stone by Mr. J. Smit from a sketch made by Joseph Wolf, but we have been unable to ascertain from what exact specimen the sketch was taken. There is a stuffed example of the Cape Hartebeest in the British Museum, obtained by the late Sir Andrew Smith during his journey to the Cape, probably the individual from which his figure in the ‘Illustrations’ was taken. There are also other specimens in the same collection, including the head of the curious hybrid between this species and the Sassaby (_Damaliscus lunatus_) described by Mr. Selous in 1893. The Cape Hartebeest, though occasionally seen in zoological gardens, has never been a common animal in captivity. The Zoological Society of London received a single example in 1851, and a fine male in 1861, presented by Sir George Grey, then Governor of the Cape Colony. In 1869 a pair were obtained by purchase. In May 1890 the Society acquired a good pair of Hartebeests imported from the Transvaal by the well-known dealer, Mr. C. Reiche, of Alfeld, in Hanover. These are still living in the Regent’s Park Gardens. _May, 1894._ 7. JACKSON’S HARTEBEEST. BUBALIS JACKSONI, THOS. (?) _Alcelaphus bubalis_, =Gray=, Ann. Mag. N. H.
