In a female from New Leon tlie wing is half an inch less than in females from Carlisle. In a 

 specimen from Charleston the colors of the throat and breast extend farther down on the belly. 



In the young of the year the wing feathers above are edged quite broadly with pale brownish 

 rusty, the throat and breast are also tinged more or less with the same. 



List of specimens.

Progne, Boie, Isis, 1826, 971. Typo Hirundo purpurea, h. 



(Jh. Bill strong, short ; the gape very wide ; tlie sides gradually compressed, the culraen and lateral margins arclied 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.
