gray, spotted with bronze feathers. A few shining blue spots 

 on breast. Rest of underside plumage, like the male. 

 Dimension slightly smaller than the male. 



It is a rare species. I have several specimens from Colum- 

 bia, and Chiriqui (Veragua). Others I killed at San Carlos 

 (Costa Rica), thinking at the time that I had discovered a 

 new species. Lately Mr. Salvin have described specimens 

 from Chiriqui under the name of Polyerata decfira ; but I 

 am of opinion that they are all one and same species, having 

 some specimens from Columbia, coloured exactly as those 

 from Costa Rica and Chiriqui. In my specimens, the central 

 rectrices have a reddish shade as in the others, the only 

 difference that I can see is that the throat of my specimens 

 from Costa Rica and Chiriqui is more bluish than in those 

 from Columbia and Ecuador.
