On the acacia plains below the eastern slopes of Elgon 

 this vulture was very rare. It was frequently seen in small 

 groves bordering the rivers and when flying or resting on a 

 branch it is hard to distinguish from Fseudogyps. 



Professor 0. Neumann thinks that the bird from Kenia 

 Colony must be named Gyps riippelli erlangeri Salvad., figured 

 as G. fulvus riippelli by Erlanger (Journ. f. Orn., 1904, Taf. II), 

 and I think he is right, because G. riippelli riippelli Bp. is dis- 

 tributed from Senegal to Chartum and White Nile only. 



In true ruppelli the dark parts of the feathers of the 

 under surface are practically black and in strong contrast to 

 the lighter tips.
