Male. — Head and neck bright metallic golden-green. Rest 

 of upperside shining green with golden reflections. Median 

 rectrices deep chestnut, tipped with shining green, the next 

 one of the same colour with one side of tip shining green, 

 the next one bluish-black, last lateral and outermost ones deep 

 chestnut, slightly tipped with bluish-black. Throat, breast,

 lustre, passing to glittering green on flanks and lower part of 

 abdomen. Undertail-coverts chestnut with green edges on 

 the upper feathers. Wings purplish-brown. Bill black.

Female. — Like the male, but smaller and not quite so 

 brilliant. 



Young Male. — Upperside shining green. Outermost rec- 

 trices chestnut, the others like that of the male. Centre of 

 throat shining blue. Rest of underside gray washed with 

 shining green feathers on sides of breast, and on flanks. 

 Under-tail coverts rufous, edged with gray. 



Total length, 4fin. Wing, 2f. Tail, if. Culmen, i. 



In my opinion all former authors have described young 

 birds as females. 



It is a common species in Colombia. 



I have specimens of both sexes from that country, and 

 others collected at Merida (Venezuela). 



One fine male collected by Goering, at Merida, has the 

 throat and breast of a lighter blue, and the median rectrices 

 with bluish-black tips. If it should prove a distinct species, I 

 propose the name of Sae^iapterus goeringi for it.
