 c. Sclerurus caudacutua brunneus Scl. 



Hub. East Colombia : Bogota coll. ; Rio Meta, between Villavicencio and 

 Mediua (Wheeler). East Ecuador: Sarayacu Buckley); Santiago (Festa). North 

 Peru: Yurimaguas, Chyavetas (Bartlett), Iquitos (Whitely). N.W. Brazil: 

 Marabitanafi (Natterer), Teffe (Hoffmanns), Bio Jurua (Garbe). 



Typical locality: Bogota collcclioiis. 



Adult. Hitlers from both the foregoing races by having the forehead and 

 sides of the head raw umber (Bidgw. iii. fig. 14) like the upper surface, without 

 any rufescent tinge, and by lacking the cinnamon on the foreneck, which is scarcely 

 shaded with tawny. 



The type of S. brunneus, a young bird, of the well-known Bogota make, has 

 only the chin white, while the throat feathers show broad brown tips, almost 

 concealing the white bases. In adult birds the whole throat is white, each feather 

 with a narrow brown apical margin, just as in S. c. umbretta.

Hub. S.E. Brazil, from Rio de Janeiro to Rio grande do Sul and west to 

 Chapada, Mattogrosso ; also in the Argentine province of Misiones. 



The occurrence in Peru requires confirmation. It must also remain doubtful 

 whether the birds from Minas Geraes, mentioned by Meuetries (I.e.) and Rcinhardt,* 

 belong to the present form or to S. c. umbretta of Bahia. 



Typical locality : Rio de Janeiro. 



Adult. This form is very different from the three preceding ones, being easily 

 recognisable by the bright ferruginous foreneck and bright chestnut rump and 

 upper tail-coverts. The sides of the head arc dark brown, the feathers of the 

 throat white with broad dark olive-grey or blackish olive apical margins. The 

 forehead is mummy-brown like the pilenm and back, without any trace of 

 rufescent. 



The Tring Museum possesses a good series of this form from S. Paulo and 

 Parana, which I compared with one of Mem-tries' original examples in the Paris 

 Museum, collected by himself in the vicinity of Rio de Janeiro.
