 genus to which it is so nearly related tliat T have liitherto allowed it only subgenerie rank in 

 the Key.) Carrion Buzzards. In general nearly like Bitteo (which see), with some resem- 

 blance to Pohjhorus. Tail more than f as long as wing. Fice outer primaries emarginate on 

 inner webs. Bill high at base ; nostrils oval, with eccentric tubercle. Tarsi lengthened and

 Turkey Buzzard, and Black Vulture. It is a cuniUKin inhabitant nf the warmer parts of 

 America and over our Mexican border; abundant in snme parts of Texas, extending E. to 

 Louisiana, rarely to Mississippi, W. acro.ss New Mexico and Arizona to Low«'r California,
