14. STXALLAXIS. 39 



The true Synallaxis rujlccqnlla of Vieillot is confined to the 

 southern part of the wood-region of S.E. Brazil. It is easily dis- 

 tinguishable from its congeners by the extension of the rufous head 

 over the front, and the slight yellowish stripe behind the eye, 

 which separates the rufous cap from the dark cinereous sides of the 

 head. 



I have examined the typical specimens of *S'. olivascms in Mr. 

 Eyton's collection. They belong to this species.
