VULTURIDJE. 7 



These are smaller and fiercer birds, and are more 

 filthy in their habits than those of the two preceding 

 genera ; they prey upon the foulest carrion, not dis- 

 daining even excrementitious matter, thereby being 

 of infinite service in clearing the surface of the ground 

 from those noxious substances.

Vultur Percnopterus. Shaiv, v. v'n.p. 33. — Vultur ginginianus-

 of the old continent.

Rather less than the immediately preceding : beak 

 and legs white : irides reddish-hazel : head and neck 

 covered with a pale ash-coloured down, mixed with a 

 few hairs, but not carunculated : the general colour 

 of the plumage is plain bluish-grey : in the old birds 

 nearly black and slightly glossy ; wings yellowish- 

 white beneath : the tail even at the end. 



The eggs of this species are two in number, and 

 are of a sooty-white. 



Inhabits nearly the same regions of America as the 

 last described, and not much unlike it in manners. 



Sp. 4. Pe. Monachus. 



Pe. Jiisco'Spadiceus, rem/gibus nigris.
