BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 425 
west as far as southern Venezuela (Mount Duida); I have come across 
no previous record of it from Brazil. 
HELIOTHRYX AURITA AURITA (Gmelin): Black-eared Fairy 
Trochilus auritus GMELIN, Systema naturae, vol. 1, pt. 1, 1788, p. 493 (“‘Cayenna’”’). 
SPECIMENS COLLECTED 
lad. 9, 1 ad. -, Brazil, Rio Maturaca, November 9, 1930. 
lim. o, Brazil, Sio Gabriel, Rio Negro, January 16, 1931. 
1 ad. o&, Venezuela, Cerro Yapacana, Upper Orinoco, April 7, 1931. 
Strangely enough, the adult male is the only one of the four speci- 
mens collected that lacks the long tail. The female and the young 
male have dusky flecks on the chin and throat, these flecks being 
larger and darker in the female. 
DISCOSURA LONGICAUDA (Gmelin): Racket-tail 
Trochilus longicauda GMELIN, Systema naturae, vol. 1, 1788, p. 496 (Cayenne). 
SPECIMEN COLLECTED 
lim. @, Venezuela, Cerro Yapacana, Upper Orinoco, April 5, 1931. 
This specimen lacks the long spatulate rackets on the tail. It also 
differs from adult birds in having the pale band across the lower back 
much more orange-tawny, less whitish. It was in process of getting 
the green goret when collected. 
Family TROGONIDAE: Trogons 
PHAROMACHRUS PAVONINUS PAVONINUS (Spix): Pavonine Trogon 
Trogon pavoninus Spix, Avium species novae .. . Brasiliam . . ., vol. 1, 1825- 
1826, p. 47, pl. 35 (“in sylvis Tabatingue et Marabitanas,” Brazil). 
SPECIMENS COLLECTED 
lad. 9, Brazil, Sio Gabriel, Rio Negro, January 9, 1931. 
lad. o’, Brazil, Salto do Hud, Rio Maturaca, November 14, 1930. 
1 ad. o', Brazil, Serra Imeri, near Salto do Hud, December 1, 1930. 
No material of P. p. viridiceps Griscom and Greenway has been 
available for comparison, but the present birds are clearly of the 
nominate race. Furthermore, Todd (Proc. Biol. Soc. Washington, 
vol. 56, 1943, p. 4) finds that viridiceps is of doubtful validity. 
This trogon appears to be rather scarce in collections; it occurs in 
Upper Amazonia west to Colombia, eastern Ecuador, and Eastern 
Peru and north to the Upper Rio Negro. It has not been reported 
from the Upper Orinoco. 
TROGON RUFUS RUFUS Gmelin: Yellow-bellied Trogon 
Trogon rufus GMELIN, Systema naturae, vol. 1, 1788, p. 404 (based on Daubenton, 
Planches enluminées . . . , p. 736: Cayenne). 
SPECIMENS COLLECTED 
3 ad. 9, Brazil, Salto do Hud, Rio Maturacé, November 21, 1930.
