plumaged males are slightly more tinged with pale slate gray above 
than are birds with more worn feathering. 
This is another of the many species that range from the Amazonian 
to the Orinocoan drainage basins without change.

and May 11-12, 1931. 
One of the May birds was noted as being in breeding condition. 
This species appears to be unknown from the Upper Rio Negro, a 
rather strange gap in its distribution as it occurs to the southeast, 
at Mandos, at the junction of the Negro and the Amazon and again 
to the southwest in eastern Peru (subsp. albitorques), and again to 
the north in the upper part of the Orinocoan system (erythrogenys) ,

SPECIMEN COLLECTED 
lad. @, Venezuela, Cerro Guanari, Brazo Casiquiare, February 4, 1931. 
As far as I have been able to learn, this is the first specimen of this 
bird recorded from the Casiquiare area of extreme southern Venezuela. 
Many years ago Wallace collected a specimen at Guia, on the Rio 
Negro, the nearest locality to the south of our present record, at which 
this bird has been taken, while a number of examples have been 
obtained at Mount Auydn-tepuf, the nearest locality to the east in 
southeastern Venezuela. 
Our specimen has been compared with 27 others in the United States 
National Museum and the American Museum of Natural History and 
is the largest one seen. It has the following dimensions: Wing 236, 
tail 110, culmen from base 53, tarsus 45 mm. The next longest wing 
length, 223 mm., was found in a bird from Mount Auyan-tepui 
(whence came also a male with a short wing of only 216 mm.). The 
tail length is almost matched by a bird from Faro, Amazon River, 
Brazil (109 mm.); the nearest culmen length to our bird’s is a male 
from Faro, Brazil (50 mm.) and another from Paramaribo, Surinam 
(50 mm.). Our bird is not only the largest one seen but is also un- 
usually richly colored, although it is matched in this respect by birds 
from Surinam and British Guiana. On the whole, it seems, strangely 
enough, that females are slightly more richly colored below, especially 
on the abdomen, than are males.
