110 WHITE WATEEBUCK —GAZELLA GRANT II 
black leopard. Ifc will therefore be interesting to gather facts 
as to the actual distribution of this peculiarity, the suspicion 
is that it only occurs above a certain altitude. 
OCCUEEENCE OE WHITE WATEEBUCK 
By A. B. Percival. 
Two very interesting examples of white waterbuck, male 
and female, both full grown, have recently been brought from 
the Northern Guaso Nyiro by Lord Gifford. 
He informs me that he saw in the one troop two bucks, 
three does, and two young, one of the latter being suckled 
by an ordinary-coloured cow. 
The eyes were normal in colour and not pink, so they are 
not Albinos. 
A V ABLATION IN GAZELLA GRANTII 
By A. B. Percival. 
A most interesting series of Grantii skins and heads were 
recently brought from the Marsabit country by Capt. Lely 
of the 2nd K.A. Eifles. 
The Grantii of this district is in colour and size very similar 
to Soemmerring’s Gazelle, but the horns are of the straight 
thick type similar to the Gazella grantii notata of Laikipia. 
The skin is of great size, far larger than the Gazella Grantii 
typica, very pale in colour, and has no black whatever either 
on side or between the fawn of the back and the white rump 
patch. In this it is similar to the Soemmerring’s Gazelle, and 
differs from Gazella grantii brighti in size and in the total 
absence of any dark markings. 
I have seen only one female skin, and that differed from 
Gazella granta typica and other subspecies in that the black 
side stripe was absent. 
It is a typical desert type of antelope, the pale fawn being 
very different from the rich colour of the other subspecies of 
Grant’s Gazelle. 
The range so far as we know at present is Marsabit road, 
but coming much further south towards the Lorian Swamp.
