RECORDS OF BIG GAME 



ISABELLA GAZELLE (Gazella Isabella). 



In all the foregoing gazelles with horns in both sexes, the horns 

 themselves have their tips slightly curved either inwards or upwards, 

 and never bent back so as to form a right angle with the basal portion. 

 On the other hand, the present species and the Muscat gazelle {G. 

 muscatensis), while resembling the foregoing in the shape of the white 

 rump-patch and the comparatively light tint of the flank-band, differ 

 by the tips of the horns being hooked inwards or upwards so as to 

 form nearly or completely a right angle. From its ally the present 

 species differs by the pale fawn colour of the upper parts ; the lateral 

 bands and other markings being also fawn, instead of blackish. Height 

 at shoulder about 25 inches. 



Distribution. — The Red Sea littoral from Suakin to Massowa, and 

 through the interior to Bogosland, Barca, and Taka.
