As already mentioned, v. Heuglin met with this Antelope during his lengthened explorations on the Upper Nile and its affluents. He described it in his memoir on the Antelopes and Buffaloes of North-east Africa (published in 1863 in the ‘Nova Acta’ of the Leopoldino-Carolinian Academy) as _Damalis tiang_, and tells us that it is one of the commonest Antelopes on the Sobat, Ghasal, and Kir rivers. He gives a coloured figure of its head. Whether v. Heuglin’s _Damalis tiang-riel_, described in the same memoir (based on some horns from the Bahr el Abiad), is referable to the Tiang is not quite certain, but Sclater, who has examined the horns upon which the species was founded, now in the Naturalien-Cabinet of Stuttgardt, believes them to be so. The only other explorer of these distant regions who has sent home examples of the Tiang is, so far as we know, Petherick, from whom skulls of an immature male and an adult female of this Antelope were received by the British Museum in 1859. The latter are represented in the accompanying figure (fig. 8). Besides Petherick, Sir Samuel Baker appears to have met with the Tiang during his journey along the Upper Nile (see ‘Ismailia,’ i. pp. 68–74); and the _Antilope senegalensis_ of Emin Pasha (‘Reise-Briefen,’ p. 144), which he encountered near Magungo, on the Albert Nyanza, may probably be referable to this species. _January, 1895._ 12.

VERNACULAR NAMES:--_Jimela_ of Uniamwezi (_Matschie_); _Topi_, _Tope_, or _Topee_ of Swahili; _Nemira_ of Uganda (_Lugard_). Size small, height at withers 43–44 inches. Fur very short and close, but mingled with it there are numerous patches of longer hairs, so that a somewhat brindled appearance is produced. General colour a peculiar purplish brown, blackish on face and chin, shoulders, and round the upper fore legs and thighs, but these darker markings are not really black and are not sharply defined. Hams scarcely lighter than the rest. Limbs and feet without dark patches, except that the backs of the pasterns are black. Fur on face directed upwards, from the extreme tip between the nostrils up to the horns, without break. Tail reaching just to the hock, its terminal half black-crested.
