SCOLECOPHAGUS, S ainson. . 



Scolecophagus, Swainson, F. Bor. Am. II, 1831. Type Oriolus ferrugineus, Gmelin. 



Ch. — Bill shorter than the head, rather slender, the edges inSexed as in Q,uiscalus, which it otherwise greatly resembles ; the 

 commissure sinuated. Culmen rounded, but not flattened. Tarsi longer than the middle toe. Tail even, or slightly rounded. 



The above characteristics will readily distinguish the genus from its allies. The form is 

 much like that of Agelaius. The bill, however, is more attenuated, the culmen curved 

 and slightly sinuated. The bend at the base of the commissure is shorter. The culmen is 

 angular at the base posterior to the nostrils, instead of being much flattened, and does not 

 extend so far behind.
