286 ZOOLOGY. 



tioning the great prevalence of mottled individuals on 

 the high plateaux of Wadela and Dalanta, At the 

 same time, Gyps RueppelU is by no means confined to 

 the higher portions of the table-land. I met with it 

 abundantly in the Anseba valley, at 4,000 to 4,500 

 feet above the sea, and a large number congregated 

 around the carcase of a cow killed by a lion at Eairo, 

 north of the Lebka valley, at an elevation of only 

 3,000 feet. But from the circumstance that I did not 

 especially notice the conspicuously mottled feathers, I 

 am inclined to suspect that the majority at least of 

 the enormous number of Grifibn Vultures which were 

 attracted to the camp at Komayli, at the base of the 

 hills, belonged to G.fulvus. At Zoulla, on the shores 

 of Annesley Bay, despite the large number of carcases, 

 Griffon Vidtures were not nearly so common as a few 

 miles further inland. 



The figure in EUppeU's " Atlas " gives by no means a 

 good idea of this bird ; the bill is not yellow, nor the 

 neck flesh-coloured : the former is dusky, the latter duU 

 ashy. Heughn (Ornith. N. 0. Afr.) has described them 

 correctly. The plumage, too, is coloured far too brown 

 by Eiippell. 



I frequently saw Otogyps auricularis, Daud., but did 

 not preserve a specimen. It is, like its Indian represen- 

 tative, 0. calvus, Scop., much rarer than other Vultures, 

 two or three occurring amongst a large number of the 

 common species. I met with it on the highlands at a 

 considerable elevation, and I occasionally saw it on the 

 Anseba and at lower levels.
