G. rucppelli, as it has a pure white lower back and rump. At 

 the same time it undoubtedly possesses fourteen tail feathers, so 

 that it cannot be assigned to the genus Pscudogyps as denned by 

 Sharpe. 



Whether a mistake has been made in regard to the number of tail 

 feathers in this species or whether the Potchefstroom White-backed 

 Vulture should be referred to another species of the genus Gyps 

 must remain for the present uncertain.
