It has been thought necessary to separate from the Sittas, the 



Xenops, lUig.(l) 



Which only diflfers in the beak being rather more compressed, 

 and the inferior ridge more convex. (2) 



Anaeates, Temm. 



In which, on the contrary, the superior ridge of the beak is some- 

 what convex, almost like the beak of a Thrush which has no emar- 

 gination. The tail, in some, is long and cuneiform, and occasionally 

 worn, a proof that it supports them in climbing, (3) 



Synallaxis, Vieill. 



A straight beak, but little elongated j very much compressed, slen- 

 der, and pointed; the tail generally long and pointed. (4) 



There are even some of them in which the stems of the tail-quills 

 are very stout, and project beyond the barbs.(5) 



Those birds which have received the name of 



Certhia, Lin. 



Or the Creepers, have an arcuated beak, but that is the only com- 

 mon character they possess. 



We separate from them in the first place, 



Certhia, Cuv. 



The True Creepers, so called from their habit of climbing trees, 

 like Woodpeckers, in doing which they make use of their tail as 

 a prop or supporter; they are known by the quills of the tail, which 

 are worn, and terminate in a stiflF point, like those of the same birds. 



There is one found in Europe, 



(1) Vieillot has changed this name Into Neops.

(4) Synallaxis rujicapilla, Vieill. Gal. 174, or Parulus rujiceps, Spix, 86, from 

 which the Syn. albescens, Tem. Col. 227, 2, and the cinerascens, lb., 3, do not appear 

 to me to differ specifically; Syn. rutilans. Col. 227, 1; Syn. tessellata. Col. 311,
