 defined, whitish. Upper Hp isabelle-fawn on the sides, whitish in 

 front ; lower Hp, chin, and throat, also whitish. Ears pale fawn on 

 the back, becoming whitish at the base on the sides ; the inner side, 

 margin, and tip with long white hairs. Horns of bucks, when seen in 

 profile, generally similar to those of G. thonisoni ; in a front view the 

 upper portion more or less distinctly lyrate, with the tips inclined 



strongly inw^ards and slightly 

 forwards. Horns of does very 

 slender, like those oi ciivieri and 

 isabella, diverging at the tips, 

 with slight but distinct rings."

 race, distinguished by the colour 

 and form of the face- markings,

 of the White Nile near Kiri, 

 by the Hon. Walter Rothschild

 of pale buffy rufous. Head and neck pale isabelline, instead 

 of rufous buff. Upper half of face and forehead pale rufous 

 mixed with white, almost entirely white between the horns. Horns 

 wider spread and more recurved backwards than in rufifrons, the 

 points more turned inwards, and the rings deeper cut and more 

 conspicuous.
