1 ? ad. from Prata, Para, November 16, 1905. No. 137. " Iris brown." 

 It has the top of the head much paler rufous than the c? sent by Robert, and 

 agrees perfectly with specimens of true F. ruficeps of Eastern Brazil, so that I can 

 no longer distinguish my F. r. amazonicus. The throat is black as in the male, 

 only narrow shaft-lines being white, which, however, are not visible unless the 

 feathers are raised.

The adult males agree exactly with the type. The young males, with the tail- 

 feathers slightly pointed, show more or less distinct rufcscent apical margins to the 

 greater wing-coverts, secondaries and rectrices. 



The female has been described by Miss Snethlage. It ditfers from the male 

 in the following details. Forehead and pileum are of a dull russet brown, lores and 

 superciliary region jiale cinereous (not black), the white postocular stripe is rather 

 narrower and bordered below by a tine blackish line. Cheeks, malar region and 

 foreneck pale cinereous, throat white, ear-coverts rufescent brown ; flanks more 

 distinctly washed with brownish than in the male. 



In all other respects the sexes are alike.

The female of C. melanogastra Mfinitr. difi'ers from that of C. roherti by its 

 much larger size, much stronger and entirely black bill (in C. roberti the lower 

 mandible being always whitish), deeji chestnut ujiper-jiarts, dull blackish instead of 

 rufescent brown ear-coverts, and by the presence of a broad, light grey superciliary 

 stripe.
