(Elliot's loc. cit.). 



The specimen from which the above description was taken 

 is unique in the American Museum of Natural History. It is 

 not in fully adult plumage. It comes close to E. dyselius, 

 which species, is from Colombia, not Ecuador, as stated by Mr. 

 Elliot. 



In my opinion it is the same species, and probably also 

 a melanism of E. cupreiventris. 



368. Eriocnemis simplex, Gould, P.Z.S., 1849, p. 96. 



Dark Puff -leg. 



r Eriocnemis obscur. 



Habitat. — Colombia. 



Male. — Much darker than E. cupreiventris^ and without 

 any glittering colours, the general tint being very dark 

 greenish olive-bronze, rather more rufescent on the upper 

 surface, and darker on the crown. 



I am of the same opinion as Mr. Salvin about this bird, 

 which is probably another doubtful form of E. cupreiventris.
