List of specimens. 



PROGNE, Boie. 



Progne, Boie, Isis, 1826, 971. Type Hirundo pxirpmea, 1,. 



Ch. — Bill strong, short ; the gape very wide ; the sides gradually compressed, the culmen and lateral margins arched to the 

 tip ; the latter inflected ; the nostrils basal, lateral, open and rounded. Tail considerably forked. Tarsi shorter than the middle 

 toe and claw, about equal to the toe alone. Toes long, strong ; lateral ones equal. 



The large size, very stout bill and feet, (for this family,) with the usually uniform black 

 glossy plumage, readily distinguish this genus among the swallows. But one species is well 

 established as North American.
