 without a faint grayish wash; throat showing more black, flanks and under tail- 

 coverts grajfish olive rather than buffy olive; back averaging more ochraceous.

 Synallaxis moesta Scl., P. Z. S., 1856, p. 26 (Bogotd). 



Common in the Tropical Zone at the eastern base of the Eastern Andes. 

 In the heavy forest of Amazonian Colombia, further south, it is replaced 

 by a darker form which I have described as Synallaxis moesta ohscura.

Inhabits the Tropical Zone from Caldas eastward. In Cauca Valley 

 specimens the breast averages paler than in those from Villavicencio (which 

 doubtless are typical) but the difference is entirely bridged by individual 

 variation in both series.
