Adult male. Similar to that of R. stnnleiii. but the sides of the 

 head and throat more soot}', not so densely black, and the elongated

This Bolivian bird, though separated from E. stanlei/i by 

 Gould and figured in his monograph, was united to i?. stanlei/l by 

 Mr. Elliot, who could see no difference between them. The 

 specimen? before me appear to justify Gould's judgment on this 

 point.
