came to the conclusion that previous authors had been in error in uniting the 
present animal and its allied forms of West and East Africa respectively 
under one head, and that they should be distinguished as different species. 
We follow Herr Matschie’s lead on this question, and have little doubt that 
his views will ultimately prove to be correct, although, from the great 
scarcity of specimens of all these Antelopes in European collections, it 
is not possible at present to arrive at a positive decision. 
The Stockholm Museum appears to have been the first to receive examples 
of this Antelope; but Sundevall referred them first of all to the Sassaby 
(Bubalis lunata), and, when he found that this was quite wrong, named 
them Bubalis koba, supposing them to be identical with the West-African 
Korrigum. Sundevall’s specimens were received from Sennaar, and are 
accurately described in his classical memoir on the “ Pecora.” 
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 (pub- 
lished 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,’ 1. 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.
