Todd’s revision of this species (cit. supra, pp. 1-3) has been found 
to hold for the total material in the U. S. National Museum, although, 
as might be expected, characters of iridescent colors are only average 
ones. The present series agrees with ridgwayi and not with typical 
examples of aurea from Demerara, and constitutes a northwestern 
extension of the known range of the race into the Upper Rio Negro 
and the Upper Orinoco Valley in southern Venezuela. 
One of the females from Sao Gabriel was in breeding condition 
when collected. 
The immature female is very much more pinkisb purple, less green 
on the back than are any of the adults. It also has the superciliaries, 
sides of head, chin, and malar area more pinkish purple, less green, 
than any of the others.

One of the Cerro Yapacana birds was in molt when collected. 
This is one of the many birds that ranges unchanged from the 
Amazonian (Rio Negro) drainage basin into that of the Orinoco. 
The Panela de Onca bird is not fully adult; it has the feathers of 
the auricular area and the area immediately behind it barred with 
blackish.

Pinto (Rev. Mus. Paulista, vol. 22, 1937, p. 308) considers the Rio 
Negro birds giganteus (Pelzeln), but the material examined in the 
present study and the data in the literature suggest that giganteus is
