Mr. Bartlett has sent two similar examples of this bird (labelled 

 male and female) from the Ucayali. It is a well-marked species, 

 easily known by its dark rusty-rufous back and clearly defined white 

 throat, the breast being light rufous. The head above is earthy 

 brown, rather darker than in F. cinnamomeus. The first primary is 

 unspotted. In the second a large rounded pale cinnamomeous spot 

 appears in the inner web about halfway up. This increases in size 

 in the third and next following primaries, and ultimately descends 

 to the base of the web. The seventh and succeeding primaries have 

 a large terminal spot of dark rufous in the inner web. There is also 

 an oblique band of dark rufous across the primaries, beginning with 

 the third, which corresponds with the markings on the inner web. 



The wings are short, the third, fourth, fifth, and sixth primaries 

 being nearly equal and longest.
