GRANT'S GAZELLE 



the tail, which is white. The lower part of the rump 

 patch is edged with broad and conspicuous black 

 markings, while the dark black band is absent both in 

 the young and in the fully adult, and the body colour 

 is much paler than in either of the two other forms. 



These points are important as showing the differ- 

 ence between it and Petersi, in which the fawn colour 

 of the back extends down the tail, thus dividing the 

 rump patch into two parts. In my opinion the latter 

 animal is not found much further north than the Tana, 

 and does not extend into the district of Biskayia. At 

 the Lorian, however, Brighti were found in consider- 

 able numbers, and I was able to obtain three good 

 specimens from that region. In the following table I 

 have given the essential characteristics of three out 

 of the eight races of Grant's gazelle found in East 

 Africa. The Pete7'si were originally described in 

 1884 as a distinct species, but now it is generally 

 regarded merely as a race of the true Grant. 



Grant's gazelle are found on open plains in deserts, 

 and on stony hills, even where one would imagine 

 there was not enough feed to keep a mouse alive. 

 They appear to be almost independent of water, and 

 it is certain that for months at a time the only moisture 

 they can obtain is the little that is contained in the 

 grasses on which they feed, but they are usually more 

 plentiful near a permanent water-supply. They are 

 often seen in company with Coke's hartebeeste, or 

 topi, and not infrequently with zebra. They may be 

 found in herds varying in size from three or four to 

 twenty and upwards. 



Of antelopes in Jubaland the most important are 

 the lesser kudu, the topi, the oryx beisa and the 

 gerenuk. The lesser kudu (Strepsiceros imberbis) is
