the white rump-patch, which only intrudes to a small extent into the 

 fawn-area, is bordered in front on each side by a narrow black line ; 

 the streak down the middle of the face is chestnut with a black nose- 

 spot ; and, with the exception of the black crest, the tail is either 

 wholly white or fawn above and white below. Typically, at any rate, 

 the hair of the neck and back has a peculiar wavy appearance, recalling 

 that of watered silk or silk-brocade. The shoulder-height ranges 

 from about 32 to 34 inches; and the weight of bucks of the typical 

 race from about 150 to 165 lb. The record horn-length is 30-^ 

 inches. 



This species has an extensive range in East Africa, and is 

 represented by the following local races, of which the distribution is 

 given by Mr. Oscar Neumann in the Sitznngs-BericJite Ges. Naturfor. 

 Berlin for 1906, pp. 241-244. 



In the typical race {Gazella granti typiccx), whose range includes 

 the interior of German and British East Africa, from northern Uhehi 

 northwards to Mount Kenia, the white rump-patch includes practically 

 the whole of the tail, only a short spur of the fawn of the back 

 extending on to its base, and the lateral bands are faint. 



The Usukuma race {G. g. robertsi), described by Mr. O. Thomas 

 on p. 119 of the Zoological Society's Proceedings for 1903, vol. ii., is 

 typically from German East Africa, its range extending from Usukuma 

 and the district at the south-east angle of the Victoria Nyanza north- 

 wards to Mara, and eastwards to Nasseria and Loita. In colour it 

 resembles the typical race, but the horns of the bucks, and in a less 

 degree those of the does, are completely twisted round inwards, so 

 that their tips are directed backwards and outwards so as to be very 

 widely sundered, thus producing a somewhat goat-like appearance. 



In the Tana race {G. g. petersi), from the Tana and lower Sabaki 

 valleys, originally described by Dr. A. Giinther in 1884 as a distinct 

 species, the stature is relatively small (32 to 33 inches) ; the fawn of 

 the back is continued all along the upper surface of the base of the 

 tail, so as to divide the white rump-patch into two halves. The horns 

 are nearly straight. The Loroghi race {G. g. notatd), from the high- 

 lands southwards and south-eastwards of Lake Rudolf to the Guaso- 

 Nyiro valley and Mount Kenia, was described by Mr. O. Thomas in 

 the Annals and Magazine of Natural History for 1897, sen 6, vol. xx. 

 p. 479. It is stated to be distinguished from the typical race by the 

 greater length, depth, and colour-intensity of both the dark and the 

 light flank-bands ; the former being black, the latter dark buff, edged 

 above posteriorly with a second dark band, less deep in tone than the
