secure one of them, which was found to weigh about 500 lbs., and was 
sufficient to supply a good dinner to the whole party. 
To Cobus defassa, we now believe, must be referred the “ Nsumma” of 
Uganda and Madi, a head of which was brought home from his celebrated 
journey by Speke, and was doubtfully referred by Sclater, in his account of 
Speke’s Mammals, to. the Sing-sing. This head is still in the British Museum, 
and on comparison of it with a stuffed specimen of the present species 
shows few points of difference. 
Speke notes that the ‘‘ Nsumma” lies concealed ‘in the high grasses in 
the daytime, and only comes out to feed in the evening. The males are often 
found singly, but the females live in herds. It does not stand so high as the 
Waterbuck, but is rather more stoutly built.” 
We believe that the “Sing-sing” of Jackson, in the volumes of the Badminton 
Library on Big Game Shooting, is also referable to the present species. 
Mr. Jackson speaks of it as follows :—‘“ The Sing-sing (also known to the 
natives as ‘ Kuru’) resembles the Waterbuck in habits, but is easily distin- 
guished from it by its darker colour, and by a considerable amount of rufous 
hair on the top of the head, as well as by an entirely white rump in place of 
the elliptical white band of the other. The horns are also, as a rule, longer 
and more massive than those of the Waterbuck, the horns of the latter never 
growing to the size that they do in South Africa. It is not met with until 
near Lake Baringo, and extends west to Uganda, where it was obtained by 
Captains Speke and Grant. It is fairly plentiful in the open bush-country of 
Turkevel; but it does not appear to go about in such large herds as the 
Waterbuck. Ihave never seen more than five or six together, and more often 
a bull and two or three cows.” 
On the river running from the north into Lake Stephanie, Dr. Donaldson 
Smith met with a Waterbuck during his recent journey. Sclater has examined 
one of the heads that he brought home (see P. Z. 8S. 1895, p. 868) and has 
referred it without doubt to the present species. 
In German East Africa, Herr Matschie recognizes Cobus defassa as well as 
C. ellipsiprymnus and gives several localities for it on the authority of 
Neumann and Bohm. The former met with it on the west shores of the Lake 
Victoria, and the latter near Lake Tanganyika and in Ugalla and Uganda. 
Bohm in his manuscript says that this Waterbuck reminds one much of a 
Stag in its appearance and mode of life. It is generally met with in largish
