Male. — Upperside shining bronze-green, with golden re- 

 flections. Uppertail-coverts reddish-chestnut. Tail chestnut, 

 all the rectrices more or less margined and tipped bronze. In 

 some specimens, especially from Costa Rica, and Guatemala, 

 the margins and tips of rectrices are purplish-black bronze. 

 Throat and breast brilliant metallic grass-green, golden in some 

 specimens. Abdomen and flanks pale brown, washed with 

 green feathers. Undertail-coverts rufous. Wings purplish. 

 Bill flesh colour with black tips. Thighs, and a tuft on each 

 side of vent white. 



Total length, 4111. Wing, 2§. Tail, 1^-. Culmen, -|. 

 Female. — Less brightly coloured than the male. 



This is one of the most common species, and with the 

 widest range. I have collected many specimens in Guatemala, 

 Costa Rica, and Panama, and I cannot see the least difference 

 between these and the specimens which I have from Columbia 

 and Ecuador. Therefore, I think as Mr. Elliot, that all of 

 them belong to the same species.
