perseverance, even in the most open and covertless spots. These beasts appear to be 
confined almost entirely to the Masai country, as I have not heard of their having been 
seen east of the Sigarari plains to the south of Kilimanjaro, or south of the Useri river 
and the head-waters of the Tsavo. I saw none at Njemps near Lake Baringo, or in 
Turkwel and Ngaboto in the Suk country, though G. granti was plentiful in all these 
places.” 
Writing subsequently in the Zoological Society’s ‘ Proceedings’ on the 
Antelopes of the Mau District of British Kast Africa, Mr. Jackson says that 
this Gazelle does not, as he believes, extend beyond a few miles north of 
Lake Nakuru. He adds that “ the females are horned, whatever may be said 
to the contrary.” With this view Mr. Arthur H. Neumann, one of our most 
recent explorers in British East Africa, quite agrees. In his lately published 
volume on ‘ Elephant-Hunting’ in that Protectorate, Mr. Neumann gives a 
figure of the head of a female Thomson’s Gazelle, which, by his kindness and 
that of his publishers, Messrs. Rowland Ward & Co., we are enabled to 
reproduce (fig. 75, p. 174): this shows that the horns are present in that sex 
of G. thomsoni, though in a much more dwarfed condition than in most of 
its allies. Mr. Neumann also claims to have met with this Gazelle much 
further north than its range is usually held to extend. This was in the 
district of Kisima, south of the Lorogi Mountains and north of Lake 
Naivasha. 
Col. Lugard, who has had great experience in East-African game- 
shooting, has stated * that he had never met with a horned female of 
Thomson’s Gazelle. A letter lately received from our much-valued corre- 
spondent, Mr. S. L. Hinde of the B.E.A. Medical Service, in response 
to enquiries on this point, endeavours to explain this diversity of opinion 
as follows :— 
«‘ With reference to the statement that the female Thomson’s Gazelle has no horns, I 
can, perhaps, give some explanation. The horns of the female of this species (see the 
skulls given by me to the British Museum) are very frail, crooked, and generally 
malformed. A good pair would be about five inches long; but a very slight blow will 
break or knock off these horns. Four or five females of this Gazelle that I have shot 
have knocked off one or both horns when falling to the shot or in their subsequent 
struggles.
