“Tris brown, feet plambeous or blackish, bill black.” 
The adult males have the tips to the sincipital feathers golden yellow, while 
in the females the top of the head is dull black, each feather with a small, rounded 
apical spot of white. The markings of the under parts are exactly as in Natterer’s 
type-specimens : foreneck regularly banded with dusky, breast and abdomen with 
dusky longitudinal stripes. Strangely enough, a young male obtained by Natterer 
at Borba, August 5, 1830—in the British Museum—undonbtedly belongs to the 
present species and not to P. borbae, for the tips of the newly grown frontal 
feathers are distinctly golden yellow! Miss Snethlage has lately met with 
P. a. aurifrons at Arumatheua, Tocantins River, 
P. aurifrons flavifrons Hargitt,* from N.W. Brazil (Teffé) | and Eastern Pern, 
differs merely by having rounded spots (instead of longitudinal streaks) of dusky 
on the belly. A specimen from Humaytha, left bank of the Rio Madeira, is 
slightly intermediate in this respect, though nearer P. a. aurifrons.

(Borba), 
_ Right bank: Borba (Natterer, Hoffmanns). 
The male may be at once distinguished from P. a. aurifrons, with which it 
agrees in the pattern of the lower parts, by the longer, brick-red (instead of 
golden yellow) tips to the feathers of the sinciput. Specimens from Itaittiba (left 
bank of the Tapajéz River),{ and the Upper Ucayali, E. Bartlett coll. in Brit. 
Mus., are identical with the types from Borba. It is strange that this species 
should occur side by side with the yellow-fronted P. a. aurifrons and P. a. flavifrons, 
still I do not think that it can be a mere colour-variety. ]
