_Antilope rubro-albescens_, =Desmoul.= Dict. Class. d’H. N. i. p. 446 (1822). VERNACULAR NAMES:--_Grysbok_ of Dutch and English Cape Colonists; _Sash-lungwan_ of Matabilis; _Teemba_ of Makalakas (_Selous_); _Cassenja_ at Senna and Tette (_Peters_). Height about 22–23 inches. Fur long and coarse, of a deep rich red colour profusely mixed with pure white hairs, whence the name “Grys” or Grey-buck. Under surface paler, but not white. Crown frequently with a black crescentic mark running round it, as in the Steinbok[1]. Ears very large, their backs grey. Limbs red. Accessory hoofs present, but very small, far smaller than in the Oribis. Tail very short, not blackened at its tip. Skull and horns very like those of a Steinbok, but the nasal bones seem to be shorter, and the premaxillæ do not reach so far backwards. A good adult male skull of this species is, however, a desideratum: we have only been able to examine immature specimens or those deteriorated by confinement. _Hab._ South Africa north to the Zambesi and Mozambique. The Forsters, who visited the Cape in 1775 during their voyage round the world along with the great circumnavigator Cook, furnished Buffon with notices respecting many of the Antelopes which at that time were met with even in the immediate vicinity of Cape Town. Amongst these was the present species, which was accordingly described by Buffon, in the Supplement to his ‘Histoire Naturelle des Animaux Quadrupèdes,’ as the Grysbok or “Chèvre-gris.” About the same period as the Forsters the learned Swedish naturalist Thunberg visited the Cape, and made himself acquainted with this and the other Antelopes of that district. In an article subsequently published by the Academy of St. Petersburg on the Mammals met with during his stay in South Africa, Thunberg named the Grysbok _Antilope melanotis_, and his specific name has usually been adopted for this species, though a subsequently given term _grisea_ of G. Cuvier has also been applied to it. In his ‘Darstellung neuer oder wenig bekannter Säugethiere,’ Lichtenstein has given coloured figures of both sexes of this Antelope from specimens in the Berlin Museum, probably procured by himself. In the days of Lichtenstein (1803–06) the Grysbok was to be found in all the middle and western districts of the Cape Colony amongst the hills, and, according to him, was particularly esteemed as game on account of its tender and delicate flesh.
