Sub-Family QUISCALINAE. 



Ch.— Bill rather attenuated, as long or longer than the head. The culmen curved, the tip much bent down. The cutting 

 edges inflected so as to impart a somewhat tubular appearance to each mandible. The commissure sinuated. Tail longer than 

 the wings, usually much graduated. Legs longer than the head, fitted for walking. 



The bill of the Quiscalinae is very different from that of the other Icteridae, and is readily 

 recognized by the tendency to a rounding inward along the cutting edges, rendering the width 

 in a cross section of the bill considerably less along the commissure than above or below. The 

 culmen is more curved than in the Agelainae. 



The only genera in the United States are as follows : 



ScoLEcoPHAGUS.— Tail shorter than the wings ; nearly even. Bill shorter thaif the head. 



QuiscALUs.— Tail longer than the wings ; much graduated. Bill as long as or longer than 

 the head.
