Carriker : List of the Birds of Costa Rica. 635 



This bird was first recorded from Costa Rica by Mr. Cherrie in 

 1893, under the name of S. albescens, but no more examples were 

 taken until 1906, when Underwood secured five specimens in the 

 Terraba Valley. Its northern limit is the head of the Terraba Valley. 

 It inhabits the clumps of bushes and weeds in the savannas and the 

 low scrub along their borders. It is very shy and not easily secured. 

 I found the birds more abundant about Buenos Aires than in any 

 other locality, but there they lived in the dense second-growth scrub 

 and were almost impossible to secure. Their alarm-note is quite 

 similiar to that of S. pudica, but much weaker, and not so harsh, 

 neither are they so noisy as that species.

Synallaxis nigrifumosa Lawrence, described from Greytown, Nica- 

 ragua, and to which he refers Costa Rican specimens, does not admit 

 of recognition, even as a subspecies, although specimens from north- 

 eastern Costa Rica are slightly different from those from the south- 

 western section. They differ slightly from Terraba specimens in being 

 a little smaller, more olive-brown above, a little darker below, and in 

 having the chestnut of the pileum and wings a trifle darker and richer. 

 These differences are very small, and in my judgment do not admit of
