PROGNE, Boie. 
Progne, Boie, Isis, 1826, 971. Type Hirundo purpurea, L. 
Ch. —Bill strong, short ; the gape very wide ; the sides gradually compressed, the cuhnen 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 swadlows. But one species is well 
established as North American.
