This specimen agrees with C. cristatus in not having the 

 black behind the red malar stripe ; but is not quite so 

 bright "yellowish olive" as the skin in the Museum 

 collection; it is, however, much worn and faded.

This common species seems slightly variable, some 

 examples being considerably brighter than others, while 

 some have less and others more markings below. 



It spends as mucli time on the ground as in the trees and 

 is often seen in the open camp a considerable distance from 

 any woods. The nesting-hole is sometimes in a post, more 

 often in a tree ; I did not succeed in securing the eggs, but 

 there are eleven in Miss Runnacles'' collection taken at 

 Ajo between October 10th and November 8th, 1909.

a. ? ad. Morlero, Paraguay. Aug. 13, 1909. 



Irides brown ; bill blackish horn-coloured ; legs and toes 

 ash-coloured. 



Size rather larger than either C melanolcemus or C. 

 cristatus; above yellowish olive, not so bright as in C. cris- 

 tatus ; rump as in C. cristatus, but paler : a strong indication
