All the species of vultures with perforate nostrils are from the new world. 

 To these belongs Cathartes fcetens ILLIG., BUFF. PI. enl. 187 (Cath. aura 

 SPIX). It is this very common species of which TSCHUDI relates that 

 black vultures in incredible numbers sit on the walls of the streets and on 

 the roofs of the houses in Peru, in midday heat, and sleep with their head 

 under their wings. Vultur aura L., VIEILL. Gal. PL 4, WILS. Am. Orn. 

 PI. 75, fig. i ; both in North and South America ; the Prince MAXIMILIAN 

 zu WIED, however, distinguishes specifically Vultur septentrionalis from 

 Vultur aura. 



A couple of species have large fleshy lobes at the base of the bill (the 

 sub-genus Sarcorhamphus DUMEK.). To it belongs a bird very common in 

 the plains of the whole of South America, Cathartes papa, Vultur papa L., 

 BUFF. PL enl. 428, LESS. Ois. PI. 5, fig. i, Diet. univ. d'Hist. not. PL 13, 

 GUEBIN Iconogr., Ois., PL i, fig. 3; the king of the kites. Another species, 

 on the contrary, inhabits the lofty mountain-range of the Andes, and has 

 in its manners a striking resemblance to the Lammergeier. It is the 

 Condor, a bird of 14 feet in the flight : Cathartes gryphus, Vultur gryphus 

 L., HUMBOLDT Observ. de Zool. PL 8, TEMM. PI. col. 133, 408 (and 494,
