 is (lark cinerous, more or less freckled with dull blackish, especially on the throat 

 and I'oreiieck. The true P. n. niijer from N.E. Pern and East Ecuador differs at a 

 glance by having the lower parts uniform deep black, the rumji and npper tail- 

 coverts black like the back (never grey as in ci iiereiventris), and by its larger bill.

This series agrees well with several specimens from the Itoraima Sluuutains, 

 British Guiana. The species has not yet been recorded from the " Cote de I'aria," 

 but Gocriiig collected it at S. Esteban, near Puerto f'abello.

 Identical with specimens from Tobago and Cnmaua. 



S. caniyuluris Ridgw. has i|nite erroneously been united with the above species 

 by Dr. Sclater. It is a very much darker bird throughout. The ui)per parts are 

 dark rufous brown (instead of pale olive brown), the foreneck deep chestnut rufous 

 (instead of pale ferruginous), breast and abdomen dark rufous brown mixed with 

 blackish, and the whole throat is uniform dark ashy grey (chin and ujipcr throat 

 not whitish, as in S. idbiijiilarix).

Three S S from Caparo, Blareh and Ajtril ; and one young bird from Laventille, 

 Blarch. 



The adults agree with a large series irom the Orinoco, Merida, Bogota, and 

 East Ecuador. Through Sclater's " lumping " of S. albescens albescens and S. a 

 albiiiiilnris in the Cut. JJ. .\v., Dr. von JIadaiasz was misled to create a new name 

 for the northern form. The latter may be distinguished from the Brazilian bird by 

 the much broader, greyish brown frontal band, paler, more greyish brown (instead 

 of reddish brown) tail, and, as a rule, lighter rufons, less castaneoiis colour of the 

 crown and shoulder patch.
