I have in my collection what I consider as the type of 

 Vieillot " Ex Coll Riocour." My other specimens were 

 collected in Chili by Reed. I have also three specimens 

 collected by Whitely in Peru, and in Bolivia by Buckley. 

 They are different in their coloration. 



The specimens from Peru have the upper part of the throat 

 black, margined with buff, and the lower part rusty red, all 

 the underside slaty-gray, with the abdomen buffy-white. 



The specimen from Bolivia has the upperside more bronzy 

 with a rufous tinge on neck, the patch on rump buffy-white, 

 all the underside deep buff, and the wings shining purple wdth 

 bluish reflections, each feather, excepting the two longest 

 tipped white. 



If they should prove distinct species, I propose the names of 

 Patagona peruviana and Patagona boliviana for them. 



I have put this genus here considering that it is more 

 nearly related to Eustephanus than to any other genus.
