of the wing edged with whity brown ; quills smoky brown below. 

 Total length 7"8 inches, culmen 0-55, wing 5-5, tail 3-3, tarsus 0-55. 



Obs. The types of Progne elcgans of Baird have been lent to the 

 Trustees bj' the U.S. National Museum ; and I find that the specimen 

 no. 21009 agrees with our female birds in the British Museum : it is 

 marked " 6 j^iv.," and may be a male of the second year. The 

 second specimen (no. 21011) is undoubtedly quite young, judging 

 from the light margins to the feathers of the upper surface, these 

 being very distinct on the wing-coverts and secondaries. The under 

 surface is ncarlj- uniform sooty brown, with ashy margins, more 

 distinct on the breast and abdomen, the under tail-eoverts rather 

 broadly tipped with white.
