Hellmayr (Catalogue of the birds of the Americas, pt. 11, 1938, 
p. 55) writes that females from northern Brazil to Peru are generally 
more strongly washed with brownish underneath than in birds from 
the Guianas, although males from these areas are indistinguishable. 
I have compared the present fine series with a good number of others 
and find that, if anything, females from British Guiana are more 
brownish, less olive, underneath than are north Brazilian examples! 
There is then, no constant color difference on which to attempt further 
subdivision of this race. 
The present series adds considerably to the known range of this bird 
in Venezuela. Hellmayr records it only from the Caura Valley, nearly 
200 miles to the east of the Brazo Casiquiare.

A male, labeled adult, from Soledad, collected on June 11, is in a 
late stage of the postjuvenal molt, the old feathers of back and wings 
being earth brown. It has a number of the red coronal and occipital 
feathers tipped with bluish black. The other Soledad male, in full 
plumage, has a few faint blackish edgings on the tips of the white 
breast feathers.

These-four males when compared with others from British Guiana 
and Cayenne seem very slightly brighter, more pure bluish, less pur- 
plish blue, on the forehead and the humeral patch. The difference, 
however, is extremely slight.
