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. grajiti ; 

 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. tJiomsoni. 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.^ 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 



' That of the female petersi has been kindly gi\en me by a friend, as I had not one 

 myself.
