SPECIMENS COLLECTED 
1 ad. o&, Ciudad Bolivar, Venezuela, June 8, 1931. 
1 ad. 2, Soledad, Anzodtegui, Venezuela, June 11, 1931. 
Both specimens are in rather worn feathering. This race is notice-

MYIOZETETES LUTEIVENTRIS (Sclater): Orange-vented Flycatcher 
Elaenia luteiventris SctaTER, Proc. Zool. Soc. London, 1858, p. 71 (Rio Napo, 
“ Keuador). 
SPECIMENS COLLECTED 
2 ad. o, lad. 9, Brazil, Sado Gabriel, Rio Negro, December 30, 1930—-January 
9, 1931. 
1 ad. 9, Brazil, Cucuhy, Rio Negro, February 2, 1930. 
These specimens agree in coloration and size with 15 others from 
Brazil, Colombia, Ecuador, and Peru, kindly lent me by Dr. J. T. 
Zimmer. Males average slightly larger than females: Wing, males 
73.4—78 (75.8); females 66-75 (73.3 mm.). 
This flycatcher does not range north across into the Orinoco 
drainage. 
TYRANNOPSIS SULPHUREA (Spix): Sulphury Flycatcher

SPECIMENS COLLECTED 
1 ad. o, Brazil, Mandos, September 26, 1930. 
1 ad. o, Brazil, Santa Isabel, Rio Negro, October 16, 1930. 
1 ad. o&, Venezuela, Chapazon, Brazo Casiquiare, January 31, 1931. 
Through the kindness of the authorities of the American Museum of 
Natural History, the Academy of Natural Sciences of Philadelphia, 
and the Carnegie Museum, I have been able to assemble a series of 
some 87 specimens from Brazil, the three Guianas, Venezuela, and 
Trinidad. 
Only two Trinidad birds, both females, have been seen (one from 
Aripa Savanna and one from La Brea), but both have broader, longer, 
and generally stouter bills than any of the continental birds and may 
represent a distinct, insular subspecies. According to Belcher and 
Smooker (Ibis, 1937, p. 233) this flycatcher is very rare and local in 
Trinidad. More material is necessary to determine the status of the 
local form. It is only in the bill that the two specimens are unusual; 
in all other parts they are matched by birds from various parts of the 
continental range of the species. There are no geographic variations 
among the continental birds. 
PITANGUS SULPHURATUS RUFIPENNIS (Lafresnaye): Rufous-winged Flycatcher 
Saurophagus rufipennis LAFRESNAYH, Rev. Mag. Zool., vol. 3, 1851, p. 471 
(Caracas).
