322 Mr. C. H. B. Grant on Birds collected in Argentina, 
of black behind the malar stripe, though nothing like to tbe 
extent in C. melanol&mus, ear-coverts washed with golden 
buff; below yellowish olive, the chest strongly washed with 
orange. 
This appears to be quite a distinct form, differing from 
C. melanolcemus in having a golden-yellow rump and being 
greener below ; and from C. cristatus in having an indication 
of black behind the malar stripe, and by the orange on the 
chest. 
The female is similar to the male, except for the malar 
stripe being black speckled with yellowish white.
