I propose to use Reichenbach's term Sqyioniis for the second divi- 

 sion of the genus Synallaxis, as arranged in my article published in 

 1874 (see P. Z. S. 1^74, p. 18), ■where I have called them ^^ /Synalhuves 

 abnormah's." These birds have 12 tail-feathers instead of 10 as in 

 typical Synallaxis. They are distributed over the jSTeotropical 

 Region from Costa Rica to Patagonia, nearly all of the southern 

 species belonging to this division. They may be divided primarily 

 into sections as follows : — 



Sect. I. Cap, wings externally, and taU. rufous, p. 58. 



II. Cap like the back, but more or less striated; wings 

 externally and tail rufous, p. 62. 

 III. Cap white ; wings and tail rufous, p. 64. 

 IV. Above nearly uniform brown ; tail more or less black mixed 

 with rufous ; tail-feathers broad, p. 64, 

 V, Above brown ; wings and tail rufescent ; giilar spot 

 bright yellovz ; tail-feathers acuminated, p, 69. 

 VI. Plumage above striated; tail-feathers pointed, p. 70. 



Sect. I. Cap, wings externally, and tail rufous. 



Key to the Species. 



A. Breast not striated. 



a. Sides of head not rufous. 

 a'. With a superciliary stripe. 



(Smaller: body beueath ochvaceous. . 1. pallida, p. 59. 

 I Larger : body beneath greyish .... 2. antisiemis, p. 59. 

 b'. Without a superciliary stripe 3. curtata, p. 59.
