abdomen black, margined with white. Tail like that of the 

 male. 



This species is common in Guiana and in Trinidad. 



I have two specimens Ex. Riocour's Collection. The two 

 are labelled Colibri Hausse-Col vert. One is marked 

 Trochilus pectoralis Vieiil, and I consider it, as the type of 

 that author. It is from Cayenne. I have one male specimen 

 from Trinidad with the tail of a bright greenish-blue under- 

 neath. 



I have also another specimen golden above, with the chin, 

 the throat, the centre of breast, and the abdomen black. Sides 

 of throat and breast shining green. Abdomen brown. Flanks 

 golden green. Undertail-coverts olive green.
