portion of their webs, are edged externally, except on the primaries, with the same colour. 

 The crown of the head is of a coppery brown ; and in certain lights there is a slight tinge of this 

 colour also on the ear-coverts. Below, the body is of a deep uniform chestnut-red with a broad 

 subquadrate bar of white on the throat. The chin is rufous, as are likewise the under wing- 

 coverts and the inner margins of the wing-feathers. The tail is short and slightly rounded — the 

 external pair of rectrices being diminutive, as usual in the genus, and only measuring about 1"9 

 inch from their insertion. The next pair are about 0*4 inch shorter than the remaining pairs, 

 which are nearly equal in length. The bill and naked lores are yellow, the apical half of the 

 upper mandible being black ; the feet are yellow, and the claws black. In Rio-Negro specimens 

 the black of the upper mandible is carried along the upper portion above the nostrils up to the 

 front. This is also usually the case in specimens from the Upper Amazons. In the latter also 

 the coppery tinge on the head is deeper, and the cheeks are pure green without any coppery 

 gloss. In all the forms the female is distinguished from the male by the absence of the white 

 throat-mark.
