Genus II. PSEUDOGYPS. 



Type.

(1878) P. bengalensis. 



This genus resembles Gyps except for the fact that it has only 

 twelve instead of fourteen tail-feathers. Two species very similar 

 to one another are known, one from India and the Malay Peninsula, 

 the other from tropical Africa, which latter just enters our boundaries.

 ally shaded with greyish ; below, brown, paler and more fulvesceut 

 in the centre of the body, the feathers with pale fulvous-white

Distrihution. — Tropical Africa from Senegambia and Abyssinia 

 southwards to Angola and German east Africa. 



This Vulture hardly comes within our limits," it has been 

 obtained, however, by Senor Anchieta at Humbe on the Cunene 

 river in southern Angola, and will probably be found in the northern 

 portions of German south-west Africa. 



* Capt. Sparrow of the 7th Dragoon Guards has recently informed me that 

 he found this Vulture quite common near Potchefstroom. It breeds in the 

 middle of June, building a very large nest in big thorns and other trees and 

 laying one egg only.
