I have not been able to see any difference between the 

 specimens which I have from Columbia, collected at Antioquia, 

 Columbia, by Mr. Salmon, and those collected by Buckley at 

 Ecuador. Therefore I think that Chlo ro stilbon melanorhynchus, 

 comptas, Berlepsch is not a valid species.

Female. — Like the preceding species, but much smaller. 



This species is closely allied to the preceding, but much 

 smaller, easily to be distinguished by the golden-reddish 

 colour of the upperside, and the colour of its tail. 



The specimens in my collection were collected by Arcé in 

 Veragua, and by me at Colon. 



I have another male specimen collected by me, at Panama 

 in December, 1876, which is of the same size, with all the 

 upperside shining green, and all the underside metallic 

 emerald-green. I propose the name of Chlorostilbon 

 panamensis for it, if it should prove new.
