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 rufons ; 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 grcyisii brown (ashy brown), the shafts of the auricular 

 feathers for the greater part whitish. Lower parts uuiform earthy brown with a 

 slight rufesceut 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 Init 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 occipnt and crown are 

 narrowly edged with buff, and the bill is longer as well as slenderer. 



An evidently 3'oung female from Borba has the sides of the head more brownish, 

 and a shorter, darker bill. 



This new species difl'ers from H. perrotii {haSr.)* 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 lower 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. unij'ormis 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.!
