1 have received a number of adult male specimens from 

 Merida (Venezuela), which have the crown of a lighter green, 

 no colour on the throat, and are golden-green. The under- 

 side is quite distinct of the colour of C. gorge. 



If it should prove a distinct species, I propose the name of 

 Cyanolesbia nier id ana for it. 



I have adopted the name gorge for this species because it 

 cannot be relied upon with certainty, on the name of T. 

 forficatus, L. for that bird.

Le Cynanthe bleu celeste. 



Habitat. — Ecuador. 



This species, which is closely allied to the preceding, can 

 be distinguished by the colour of the underside, which is 

 coppery brown. As it is constant, I think the species is valid. 

 The specimens which I have of this species were collected in 

 Ecuador bv Bucklev.
