Hab. Kavirondo and Uganda. 
Thomas’s Kob, as it has been lately proposed to call the representative of 
this group of Antelopes in Kavirondo, Uganda, and the adjoining districts 
of Africa, after one of the authors of the present work, has been known for 
many years; but it has been unfortunately confounded with Cobus leucotis, 
C. vardoni, and C. kob, and has only been recently recognized as a distinct 
species. Although not unlike the White-eared Antelope, it is really much 
more nearly allied to the Kob of West Africa, of which it is in fact a larger 
form. From the Poku (Codus vardoni) it is at once distinguishable by its 
black legs. 
The first specimens of Thomas’s Kob that reached England were two 
heads brought home by Speke on his return from his celebrated East-African 
expedition in 1863. These were examined by Sclater, and in his report on 
the Mammals of the expedition (P. Z. 8. 1864, p. 103) were erroneously 
referred to C. leucotis. But a re-examination of one of the specimens, which 
is now in the British Museum, has convinced us that it is undoubtedly 
referable to the present species. Speke remarks that this Antelope, of which 
the native name is ‘‘ Nsunnu,” is “ found in Uganda, Unyoro, and Madi, but 
never south of those countries. They roam about in large herds in the thick 
bush and grassy plains, but never go far from water.” 
So far as we know, the next example that reached Europe of the present 
species was that of an adult male received by the British Museum from 
Mr. F. J. Jackson in 1891, from which our figure (Plate XX XIX.) has been 
taken. ‘This specimen was mounted and placed in the Mammal gallery, and 
named at first C. vardoni, and afterwards C. kob. Other examples of the same 
Antelope were subsequently received at South Kensington from Mr. Gedge, 
Capt. Lugard, and Mr. Scott Elliot, and referred to the Kob. Mr. Gedge’s 
specimens were obtained in Uganda, Capt. Lugard’s on the south-west coast of 
the Albert Nyanza, and Mr. Scott Elliot’s near the Albert-Edward Lake. 
In the autumn of 1895, Herr Oscar Neumann, the distinguished German 
traveller and naturalist, came to the British Museum for the purpose of 
examining the Mammals in the collection, and of comparing them with the 
specimens he had himself obtained during his journeys through German and
