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 .">, 1S30 — in the British Museum— undoubtedly belongs to the 

 present species and not to F. borhae, for the tips of the newly grown frontal 

 feathers are distinctly golden yellow ! Miss Snetblage has lately met with 

 P. a. aurifrons at Arumatheua, Toeanfins River. 



P. aurifrons jlaci/roiis Hargitt,* from N.W. Brazil (Tefle) f aud Eastern I'ern, 

 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. aari/rons.

Right bank : Borba (Natterer, Hoffmanns). 



The male may be at once distinguished from /'. a. auri/rons, with which if 

 agrees in the })attern of the lower parts, by the longer, brick-red (instead of 

 golden yellow) tips to the feathers of the sinciput. Si)eciraens from Itaituba (left 

 l)ank of the Tajjaji'iz River), J and the Upper Ucayali, E. Bartlett coll. in Brit. 

 Mus., are identical with the types from Borba. It is strange that this s])ecies 

 should occur side by side with the yellow-fronted P. a. aari/rons and /'. a.Ji'vifrons, 

 still I do not think that it can be a mere colour-variet)-.]
