Male. — From British Guiana. Upperside shining golden- 

 green, excepting the head, which is greenish-blue with the 

 centre of crown golden-bronze. White spot on neck. Median 

 rectrices white at base, then greenish-bronze with bluish-black 

 tips, rest white with a bluish-black spot at tip, narrowly 

 margined with white. Throat dark blue with greenish re- 

 flections. Flanks golden-green, rest of underside pure white. 



"/ I propose the name of F. guianensis for this species, if it 



should prove distinct. I have three specimens, one from 

 Demerara and two from River Atapuroni, B. Guiana, collected 

 by H. Whitely.

 at base passing to bluish black, the next one white with bluish- 

 black tip, the last three white with a very minute brown spot 

 on tip of the one next to outermost one, this last one, pure 

 white. Wings purplish-brown. Bill black.

Female. — Upperside bright golden-green, brownish on 

 head. Uppertail-coverts shining green. Median rectrices

 and slightly margined with white, outermost ones bronze-green 

 at base with broad subterminal bluish-black bar, margined on 

 outer web with broad white tips. Chin and abdomen pure 

 white, throat and upper part of breast pure white, margined

, I propose the name of F. peruviana for this species, if it 



'^ should prove distinct. I have four specimens of this species, 



one collected by Buckley in Ecuador, two collected by 

 Garlepp in Ecuador, and one by Hauxwell, at Pebas, Peru, in 

 1866. I have also one specimen exactly like the preceding 

 wdth the bill one inch long. I believe that it is what Gould 

 described as F. flabellifera.
