is not, known either, it having been sent to Mr. E. Wilson " from the upper brandies 

 of the Amazon river." 



The female differs from the males in lacking the fiery-red crown-spot and 

 the blackish jugular band ; by having the top of the head brownish olive-green 

 like the back (not deep black) ; the sides of the head sooty grey instead of deep 

 black ; the throat dull bnffy greyish (not silky white) and by the chest being 

 dull pale cinnamomeons like the belly (instead of being dark hazel). From the 

 ? of H. jfamtertcx it may at once be distinguished by the dull brownish olive, 

 instead of bright oil green, colour of the upper parts.

One of the adult males (No. 987) agrees with specimens from the Rio Napo 

 and from Nauta, Peruvian Amazons, in being uniform glossy black on the upper 

 and under parts, but there is a slight slaty suffusion on the vent and under tail- 

 coverts. Iu the two other males the under-surface is duller, more sooty blackish, 

 and the upper tail-coverts show cinereous edges and transverse bars. 



In a large series of skins from Trinidad, Venezuela, British Guiana, Surinam 

 and Bogota-collections, the lower parts are still lighter, slate-grey, more or less 

 washed with blackish on the throat and foreneck, and occasionally freckled with 

 whitish in the middle of the belly ; and the rump as well as the upper tail- 

 coverts are nearly uniform cinereous. If these birds are not referable to 

 P. n. cinereiventris* then they must have a new name. 



The females of P. n. niger and P. n. cinereiventris (?) differ from those of 

 P. a. atricapillus and P. a. marginatum iu their larger size, by having the back 

 strongly washed with brownish, and by the pilenm being brownish like the 

 mantle. In P. a. atricapillus and its southern ally the back is of a pure light 

 olive-green and the pilenm distinctly rufescent, forming a well-defined cap.
