Subfamily II. SYNALLAXIN.E. 



The Synallaxina^ embrace the first section of the non-terrestrial, 

 bush-haunting Dendrocolaptidce, distinguished from the second 

 section by their small Sylviine bill and long tail. It is somewhat 

 difficult to draw the line between them and the PJiilydorincp, and I 

 have altered the division adopted in tbe ' Nomenclator ' between 

 these two nearly allied groups, by relegating the last seven genera 

 as there assigned to ihe succeeding subfamily. 



The Synalh(.vince extend in more or less abundance nearly all 

 over the Neotropical Region except the Antillean Subregion.

Type. 



Oxyurus, Siv. Zool. Journ. iii. p. 354 (1827) O. spmicauda. 



This curious form is closely allied to Synallaxis in general struc- 

 ture, but differs in its peculiar tail, the stems of the twelve rectrices 

 being rather stiff'ened, and having their denuded ends produced 

 beyond the termination of the barbs. The genus is restricted to the 

 Patagonian Subregion.
