Small Trochilidse (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 " XXwpoc, viridis, et ar/A/Jw, conisco." (Gonld.) 

 bSee Introduc. Troch., 186], 175.

 « "Von noDJu (gar sehr) und x^^'^P^C (griin)." (Cabanis and Heine.) 

 /The variation in length is caused by varying length of the tail, which in some 

 species equals nearly half the total length.
