Adult male. Upper surface dark grass-green, the lower back and 

 rump bronzy, a long postocular white stripe, under it a black 

 patch, followed by a patch of dark violet-blue glittering feathers ; 

 throat dull glittering green, becoming duller on the breast, on 

 either side of which is a white patch ; rest of the under surface 

 dull grass-green ; tail dark green, tipped narrowly with white, 

 and the lateral rectrices crossed by a wide subterminal steel-blue 

 band. Total length about 3-5 inches, wing 2'05, tail 1"3, bill 0"7. 



Female ? Like the male, and also with glittering violet-blue 

 feathers on the sides of the neck ; but the chin and throat, together 

 with the middle of the breast and abdomen, dull green. 



Buckley's Bolivian skins seem certainly referable to this species.
