BIRDS—ICTERIDAE—SCOLECOPHAGUS FERRUGINEUS. 551 
SCOLECOPHAGUS, Swainson. 
Scolecophagus, Swatnson, F. Bor. Am. II, 1831. Type Oriolus ferrugineus, Gmelin. 
Cu.—Bill shorter than the head, rather slender, the edges inflexed as in Quiscalus, 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.
