( 330 ) 
contrasted with colour of crown ; lower rump and upper tail-coverts chestnut. 
Upper wing-coverts cinnamon-brown, somewhat paler and duller than the back, the 
inner webs of the greater series more rufous; remiges chestnut, the outermost 
primaries narrowly edged with brownish. Tail uniform chestnut. A narrow rim 
round the eye bare of feathers, only a few small plumules on the lower edge of the 
eyelid. Sides of the head (viz. lores, cheeks, malar region, ear-coverts, and 
superciliary region) dull greyish brown (ashy brown), the shafts of the auricular 
_ feathers for the greater part whitish. Lower parts uniform earthy brown with a 
slight rufescent tinge, more conspicuous on sides, flanks, and under tail-coverts. 
Under wing-coverts dull orange, mixed with brownish towards the edge of the 
wing ; broad margin to inner web of remiges orange-buff. Bill dark red. 
The adult female obtained by Natterer agrees with the type but for the slightly 
more rufescent breast and abdomen. 
Another, immature, male from Borba is even more strongly washed with 
cinnamomeous on the lower parts; the feathers of the occiput and crown are 
narrowly edged with buff, and the bill is longer as well as slenderer. 
An evidently young female from Borba has the sides of the head more brownish, 
and a shorter, darker bill. 
This new species differs from H. perrotii (Lafr.) * in several important points. 
The latter bird is larger (two Cayenne skins in the British Museum measure : 
wing 135—140; tail 120—122 mm.); the anterior portion of the throat is buffy, 
in conspicuous contrast to the brown chest, etc.; the middle of the belly shows 
more or less distinct dusky cross-lines ; furthermore, there is a well-defined dingy 
white band running from the nasal plumes under the eye to the Jower portion of the 
auricular region. 
H., perrotii has been described from Colombia. This locality, however, was 
most probably erroneous, since the specimens in the British Museum, skins of 
the unmistakable Cayenne make, agree perfectly with Lafresnaye’s original 
description. 
H. uniformis is, as yet, only known from the right bank of the Rio Madeira, 
and the four specimens described above are the only ones in European collections.+
