Genera of Hiiiiiniing Birds. 263 



This species was probably discovered in Columbia, by 

 Boissonneau, the author of the species. 



My specimens from Peru, and Bolivia collected by M. M. 

 Whitely and Buckley, are larger, and slightly different in 

 colouration. The upper and underside are of a darker green, 

 the median rectrices and uppertail-coverts are not bronzy, 

 but dark shining green, the lateral and outermost ones are 

 dark bronzy-brown margined with brownish-black. If they 

 should prove distinct, I propose the name of Pterophanes 

 Peruvianus, for that species, Whitely's specimens from Peru, 

 havlng"been collected first.
