Descriptions of two new Species of Humming Birds, from, Peru, 

 By John Gould, F.R.S. 



1. Spathura cissivra. 



General plumage bronzy green ; wings purplish brown ; four outer 

 tail-feathers purplish steel-black ; under surface green, paler on the 

 throat ; thighs thickly plumed and of a reddish buff. 



Total length, 4j inches; bill, f ; wing. If; tail, 2f. 



Hab. Peru. 



Remark. — Most nearly allied to Spathura Peruayia, but differing 

 from that and all the other members of the genus, in haNnng the outer 

 tail-feathers webbed throughout their entire length, and consequently 

 the spathulate tips less conspicuous.
