This series shows a great deal of variation, extreme individuals 
looking as if they might well belong to separate subspecies. However, 
these variations appear to be individual, not geographic. It may be 
recalled that Zimmer (Amer. Mus. Nov., No. 647, 1933, p. 19) found 
similar variability in his much longer series. His comments might 
have been based on the present material, so well do they apply.

SPECIMENS COLLECTED 
2ad. o,3ad. 2, Brazil, Sio Gabriel, Rio Negro, December 31, 1930—January 
15, 1981. 
1 ad. o&, Venezuela, Raudal Corocoro, below Playa de Candela, February 9, 
1931. 
lad. o&, Venezuela, Brazo Casiquiare, Cafio Durutomoni, February 19, 1931. 
lad. 9, Venezuela, Brazo Casiquiare, near Caio Mabinagui, February 20, 1931. 
lim. 9, Venezuela, Brazo Casiquiare, below Caio Caripo, February 22, 1931. 
lad. 9, Venezuela, Upper Orinoco, near Cerro Cariche, February 24, 1931. 
The male from the Brazo Casiquiare, at Cafio Durutomoni, although 
labeled as adult is either immature or wrongly sexed, as it has the 
female type of plumage, but has small white spots at the tips of some 
of the lesser upper wing coverts and has the posterior crown as well 
as the occiput gray. 
The characters on which this race is founded are not wholly 
constant but are only average ones. Thus, two of the females in the 
present series have the occiput as brown as a female from Peru 
(P. s. maculipennis) and have the back with considerable olive- 
brownish tinge. On the whole, however, occipitalis appears to be a 
readily recognizable form. 
Two other specimens from Sao Gabriel, January 12, 1931, were 
saved in alcohol.
