FIRST EXPEDITION FROM MOMBASA 
But one animal, to which considerable interest attaches, 
deserves more particular mention. In some parts of the 
country to the left (or south) of the road between Duruma and 
Taita—as, for example, about Pika-Pika and Kisigau, and 
sometimes not far from Ndara—a gazelle is to be found about 
which naturalists seem somewhat confused, namely G. petersi. 
Some authorities seem to re¬ 
gard this antelope as a mere 
local variety of G. granti; 
but I am strongly of opinion 
that it is quite distinct, and, 
while taking the place of the 
latter in the coast regions, 
may be regarded as almost 
intermediate between it and 
G. thomsoni. I am able to 
illustrate this by a photograph 
of a series of skulls of the 
three species in my possession. 
These have, I may explain, 
not been specially selected, 
but are some of those I have 
shot, which I happen to have 
kept. 1 It will be seen that they form a regular gradation, 
the females corresponding exactly with the males in their 
peculiarities. I am sorry that I have not been able to figure 
a female Thomson’s' gazelle skull, as it appears there is not 
one in England, not even in the Museum. I have, however, 
been kindly given the photographs of two mounted heads 
(the only ones, so far as I can discover, in existence in this 
country), one of which is reproduced. It is a curious thing 
that the female of this last gazelle seems almost to be in a 
state of uncertainty as to whether it ought to bear horns or 
1 That of the female petersi has been kindly given me by a friend, as I had not one 
myself.
