Female. — Upperside dark shining-green, brown on head. 

 Uppertail-coverts shining blue, edged with white. Centre of

 under the ear-coverts, buff. Rest of underside slaty-gray, 

 passing to buff on the abdomen. Lateral rectrices with tips

I have collected both sexes of this species in Costa Rica, 

 in 1877. I have also some specimens collected by Arce, in 

 Veragua, by Buckley, in Ecuador, one specimen collected by 

 Whitely, at Huiro, Peru, and others from Colombia. To me 

 there is no doubt whatever that P. yaruqui, is identical with 

 this species, and 1 believe that P gnyi will probably turn out 

 to belong also to the same species.
