GRANrS GAZELLE 263 



main flank-band, but decidedly darker than the middle line of the 

 back. The dark band to the white rump-patch is also broader, and 

 deep black in colour. The horns are nearly straight, as in petersi. 

 The type specimen was killed in the Loroghi Mountains of British 

 East Africa. 



The Lado race (6^. g. brighti), named by Mr. O. Thomas, on the 

 evidence of specimens from the district between Lado and Lake 

 Rudolf, on page 805 of the Proceedings of the Zoological Society for 

 1900, is a rather small form, of very pale colour, with no dark lateral 

 bands. The white of the rump-patch intrudes deeply into the fawn of 

 the back, so as to completely surround the tail ; the dark band to this 

 patch being short, narrow, and in some cases well-nigh obsolete. The 

 horns are relatively short, with the immature boss on the front of the 

 base retained in the adult, and covered with a distinct tuft of hair. 

 This race inhabits the district between Lake Rudolf and the Nile, 



Lastly, we have the Abaya race {G. g. lacuuui), from the neighbour- 

 hood of Lake Abaya, named by Mr. O. Neumann in the paper already 

 cited, which is characterised as follows : — In size this race is inferior 

 to the typical form, with the horns nearly straight, as in petejsi and 

 notata. The general colouring is similar to typica, but the white 

 rump-patch is smaller, with no trace of any intrusion of the fawn-area 

 in the region of the tail, and the dark border to the rump-patch fainter 

 and less defined. The dark flank-band, although distinct in the young, 

 becomes nearly obsolete in the adult ; this character, together with 

 the long straight horns, distinguishing this race from brighti. 



Some at least of these races are known to intergrade. The 

 following account of the typical race is abbreviated, and otherwise 

 slightly modified, from one furnished by Mr. A. H. Neumann : — 



" Grant's gazelle is not, so far as I know, found anywhere within 

 at least 150 miles of the sea (in the coast-belt its place being taken 

 by the somewhat smaller race pelersi) ; but in the interior, except in 

 densely bushed or rankly grassed areas, on high mountains, or, of 

 course, where the land is much cultivated and thickly peopled, one can 

 hardly ever travel a day without seeing at least a few specimens of 

 this ubiquitous species. Alike in bushy wildernesses and treeless 

 wastes, on level plains and stony hills, even the most rugged — as at 

 the southern end of Lake Rudolf, where there is little but bare rock — 

 Grant's gazelle is at home ; but in the open country it finds its most 

 congenial habitat, and there it is most numerous. 



" It is often seen in company with zebra, oryx, or (in their own 

 districts) Coke's hartebeest, or topi, and not infrequently with giraffe ;
