1 Antenor Ridgway. J¥ov. subgen. 



Ch. Intermediate between Buteo and Urubitinga, having the long wings, robust 

 feet and claws of former, and the elongated legs, and bill of the latter. Inner webs 

 of outer five primaries emarginated, as in Buteo, in which, however, never more 

 than four are cut. Lores naked. Type Falco unicincta Temm. 



The name "Craxirer Gould," cannot be used for this species, since its type was 

 Buteo galopagoensis Gould, a bird strictly congeneric with B. borealis.
