386 Mr. O. Thomas on 
the caama type, with V-shaped horns. Another similar 
specimen from the Bahr el Gazal, also female, was sent to 
the Museum in 1884 by Mr. F. Bohndorff. Noticing their 
relationship to B. caama, about a year ago I made many 
endeavours to find out what had become of Petherick’s male 
specimens or to get hold of another, but without avail. That 
a caama-like species occurred in this region was clear, for 
Heuglin * also speaks of the occurrence on the White Nile 
of a Hartebeest which “scheint mit A. caama zusammen- 
zufallen,” and it was therefore with much pleasure that in 
Mr. Jackson’s hartebeest I recognized a species very possibly 
identical with that observed by Petherick, Heuglin, and 
Bohndorff. At the same time it must be said that while the 
horns of Petherick and Bohndorff’s specimens correspond 
with small and slender female caama horns, those of Mr. Jack- 
son’s skull equal or exceed in size the very largest male 
caama horns that I have seen. Male specimens, with skins, 
from the Upper Nile are therefore needed to confirm or upset 
this identification. 
I propose to call the species 
Bubalis Jacksont, sp. n. 
Similar in essential characters, in size and proportion of 
skull, and in the curves and direction of the horns to the 
South-African B. caama, but distinguished by the uniform 
pale colour of the face, which matches that of B. tora and is 
entirely without any trace of the black frontal and nasal 
patches characteristic of that species. Hair of nasal region 
reversed upwards for only about 4 or 43 inches from the 
hairy point between the nostrils T. 
Hab. Country between Lake Victoria Nyanza and Lake 
Naivasha. Its northward range depends on the correctness 
of my identification of Heuglin’s and Petherick’s animals with 
it, and this must of course remain doubtful until further 
information is obtained. 
* N.O.-Afr. ii. p. 128 (1877). 
+ The extent of the reversed hair on the face seems to be character- 
istic of the different species of the genus. Thus it extends up to between 
the eyes in B. caama, or even to the horns, while in B. major, tora, and 
Coker it is confined to about 13 or 2 inches on the tip of the muzzle. In 
B. Lnchtensteini it is reversed on the nasal region, points downwards on 
the anterior frontal, and is then again reversed up to the base of the 
horns. No doubt larger series than I have been able to examine will 
show these characters to be more or less variable ; but the species are all 
so closely allied to one another that any characters which may help to 
separate them are worthy of mention.
