Small Trochilide (length about 70-100 mm./) with straight, narrow 
bill about as long as head, tail more or less forked or emarginate 
(rarely nearly truncate or slightly double-rounded in female), with 
lateral rectrices decidedly narrower than middle pair, the adult males 
with under parts wholly brilliant metallic green and tail (except in 
species of ‘‘Panychlora”’ group) blue-black, the middle rectrices 
sometimes tipped with gray; adult females gray beneath, lateral 
rectrices green or grayish basally, blue-black terminally or subtermi- 
nally, the outermost (at least) tipped with pale gray. 
Bill slender, straight, nearly terete, about as long as head; culmen 
broadly rounded but basally contracted into a more or less distinct 
a“ Xiwpoc, viridis, et otéABw, corusco.’? (Gould.) 
b See Introduc. Troch., 1861, 175.

f The variation in length is caused by varying length of the tail, which in some 
species equals nearly half the total length.
