a tendency to be recurved upwards. Good male horns are of a length over 
the curves of 21 inches. 
This and the two next species are very closely allied in all their essential 
characters ; but their colour-differences appear to be sufficiently constant in 
their respective localities to entitle them to specific recognition.

The Antelope described by Buffon, in his ‘ Histoire Naturelle,’ as the 
“Koba”* or “Grande Vache Brune” of Senegal, has proved a great 
stumbling-block to naturalists. This has been largely due to the fact that 
Bufton appended to his description of the Koba the figure of some horns 
from a totally different source, and clearly of a different animal, which, indeed, 
we believe to have been simply those of the Pallah (pyceros melampus). Not 
noticing this confusion, many good authorities have identified the Koba with 
the present species, while others have been inclined to refer it, owing to the 
figure of the horns erroneously given by Buffon, to the Bontebok of the Cape 
and to other Antelopes. ‘The description by itself is quite unrecognizable, 
and under the circumstances, as the matter must ever remain uncertain, the 
best course seems to be to ignore Buffon’s animal altogether, and to reject 
the specific names koba and senegalensis that have been founded upon it ; 
although there can be no doubt that the Korrigum, as now described, is the 
Antilope and Damalis senegalensis of Children, Hamilton Smith, Gray, and 
many other authors. 
‘This being decided, the proper name to adopt for this Antelope will be 
korrigum of Ogilby. Ogilby proposed this name in a communication made 
to the Zoological Society of London in 1836, basing it on the head and horns 
brought home from Bornou by Denham and Clapperton on their return from 
their celebrated expedition into Central Africa in 1822-24. This skull is 
still in the collection of the British Museum.
