The series is fairly uniform except for the bird from the Rio Caua- 
bury, which is distinctly lighter, more whitish below, and has the dark 
cross bars of the lower surface considerably restricted. 
The identification of these skins as typical melanoleucos agrees with 
the findings of Pinto (Rev. Mus. Paulista, vol. 23, 1938, p. 515) for 
skins from Sao Gabriel and elsewhere in Amazonas, Brazil.

The unsexed (but probably female) bird from Serra Imeri is more 
richly golden on the upperparts than any of the others and has 
sagittate whitish basal marks on the interscapulars and feathers of the 
upper back. 
Griscom and Greenway (Bull. Mus. Comp. Zool., vol. 88, 1941, p. 
203) consider cassini a race of affinis. In spite of the admittedly close 
similarity, this cannot be maintained, as both cassini and orinocensis 
occur together on the Caura and the Upper Orinoco. It follows, 
therefore, that cassini must be treated as a distinct species, differing 
from orinocensis (its geographic neighbor) in having prominent tri- 
angular spots of buff on most of the upper wing coverts and in having 
the ventral barring more black and white, less olivaceous. I am in- 
debted to W. H. Phelps for this information.
