Two of the males agree perfectly with those from Itaituba, while the third 

 slightly points to //. m. melanolaema, having the breast a shade greyer and the 

 snperciliaries rather narrower. 



The females are entirely typical, the throat being ochraceous like the belly, 

 and the whole bill black. They differ from the type merely by their larger white 

 interscapular patch. In No. 1435 the under parts are even deeper ochraceous than 

 in the type from Itaituba.

The specimens from Humaytha are practically identical with others from 

 Chuchurras (Hnaunco, Central Peru) and San Mateo (North Bolivia). The males 

 show exactly the same clear cinereous colour of the under parts, and the snperciliaries 

 are equally narrow and ill-defined, while the females also agree with one from 

 Bolivia in having the throat white, the rest of the lower surface ochraceous buff, 

 and the under mandible dull whitish. 



The male from Paraizo, though not quite adult, appears also to belong to the 

 present form. 



H. m. melanolaema is new to the Brazilian avifauna.
