There is much difficulty in distinguishing some specimens of this 

 bird from F. hoffmanni on the one hand and.jP. crissalis on the 

 other. The lores are quite black in typical specimens ; but in others 

 there is a white speck on them, sometimes more apparent on one 

 side than on the other.

Above olive-brown, head rather darker ; rump brighter ; lores 

 black, with a white spot ; sides of neck pale rufous ; tail-end blackish : 

 beneath cinereous ; throat and neck black ; middle of belly paler ; 

 crissum rusty red ; broad band on the underside of the wings 

 crossing the inner webs of the remiges at their base pale fulvous ; 

 bill black ; feet pale brown : whole length 7 inches, wing 3"5, tail 2*1. 

 Female similar. 



Hab. Venezuela, Guiana, and Lower Amazonia. 



The white spot on the lores is not a safe diagnostic point of this 

 species from F. analis, as indications of it appear in some specimens 

 of the latter. The paler greyish under surface and rufous sides to 

 the neck seem to be better characters ; but it is difficidt to decide 

 to which form to refer some of the specimens without the aid of 

 locality !
