List of Specimens examined. 



1. Oyapok, Cayenne {Jelski, 1867), Mus. P.L. S. (type), 



2, 3. Bartica Grove, B. Guiana {Whitely), Mus. S.-G. 



4. Corentyn river, B. Guiana {im Thurn), Mus. P. L. S. 



This species was originally based upon a single skin in my 

 collection, obtained at Oyapok in 1867, and labelled '^ Sylvia 

 muscicapina " by a collector then unknown to me, but whom 

 I now believe to have been M. Jelski, the well-known natu- 

 ralist of the Warsaw Museum. As will be seen by the list 

 above given, it has since been obtained by other collectors in 

 the neighbouring colony of British Guiana. 



Sect. B. Species pileo circumscripte rufo.
