 ■wing-coverts and scapulars like the back : median and greater wing- 

 coverts and quills blackish brown, with a slight steel-green gloss ; 

 tail-feathers blackish bro^n, with dusky cross bars under certain 

 lights; lores velvety black; ear- coverts and sides of neck glossy 

 greenish black ; checks and under siirface of body clear earthy 

 brown, including the thighs ; under tail-coverts blackish brown,

 Godman collection, measures as follows : — Total length 5-8 inches, 

 culmen 0-25, wing 4-4, tail 1-25, tarsus 0-45. 



The shade of colour on the upper parts varies between steel-blue 

 and steel-green, as is the case with other American Swallows, the 

 bluer shade indicating, as I believe, a fresher slate of plumage.

 below ashy white, the throat dark brown. 



Hah. The Andes of Peru, Ecuador, and Colombia.
