 Specimens of both sexes of this lovely species. The female has 

 not been previously obtained, as far as we know. 



19. Dacnis analis, Lafr. et D'Orb. 



Hab. Upper Ucayali. 



These skins agree with a skin from British Guiana in Sclater's 

 collection, and must be referred to D. analis, while the Brazilian re- 

 presentative, D. speciosa (united with it in Sclater's catalogue and 

 elsewhere), is probably distinct, being altogether paler in coloration, 

 especially below.

A male specimen agrees best with Sclater's Bogotan skin, which 

 differs somewhat from the typical E. melanura from Barra, as noted 

 in his American Catalogue, p. 59.
