It is just possible that this may prove to be the female oi E. sqiiamata ; for I have received many specimens from 

 Professor Jameson with wholly white puflFs, which is the characteristic of £^. lugens-, while from another locality 

 one has been sent with partly white and partly red puffs : independently of the difference in the colouring of the 

 puffs, the latter birds are larger than the former. 



312. Eriocnemis Aureli^ . , VoL IV. PL 283. 



Habitat. New Granada and Ecuador. 



Specimens from the Napo differ considerably from those received from Bogota, — a deep coppery hue pervading 

 both the upper and under surface, whereas those parts are green in the Bogotan birds. I have seen specimens 

 which I consider may be females or young of this species with wholly white puffs. 



Proceeding from Mexico, southwards, through the high lands of the temperate regions of Guatemala, Costa 

 Rica, and Veragua, we there find several species of the well-defined genus Cyanomyia which do not pass the Isthmus 

 of Panama, while others occur in New Granada, Ecuador, and Peru. I have not yet seen any species of this form 

 from Brazil or from any of the eastern portions of the South American continent. They are all very lovely birds, 

 the colours with which they are adorned being blue, glittering green, and white, to which the red bills of one or 

 two of them offer a pleasing contrast. The females, although generally resembling the males, are inferior to them 

 in size and colouring. With these birds I commence the fifth volume.
