BACKED VULTURE. 
Senor Anchieta states that this species is common at Humbe on the 
Cunene River; native name Kubi. Professor Barboza du Bocage 
suggests that the Gyps kolbii identified by Andersson in Damara 
Land, but of which no specimen was sent by him to England, may 
after all have been the present species. We think this very likely.

back and wing-coverts blackish brown; lower back and rump pure 
white; upper tail-coverts brown; some inclining to blackish ;

shade; ruff white, rather scanty ; crop-patch brown ; rest of under

Near Lydenburg, Rustenberg, and sparingly throughout the Transvaal 
and Free State (Barratt).
