BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 453 
(both maxilla and mandible) dusky, whereas in the adult birds the 
mandible is pale. 
In the absence of adequate material to enable us to come to an 
independent conclusion, we follow Zimmer (Amer. Mus. Nov., No. 
728, 1934, pp. 14-15) in separating bartletti from typical merula.

SYNALLAXIS ALBESCENS TRINITATIS Zimmer: Venezuelan White-throated Spinetail 
Synallaxis albescens trinitatis ZimmMER, Amer. Mus. Nov., No. 819, 1935, p. 2 
(Princestown, Trinidad Island). 
SPECIMENS COLLECTED 
2im. o&, lim. 9, Venezuela, Soledad, Anzodtegui, December 1-7, 1929, and 
June 11, 1931. 
One of the males and the female resemble the adult plumage; the 
other male, a much younger bird, has the entire top of the head buffy 
olive-brown with no chestnut cap. The chestnut patch on the bend 
of the wing is also paler and is much reduced in extent, comprising 
only the outer margins of the feathers; the tail is only two-thirds 
grown, and the bill is also considerably smaller than in a full-grown 
specimen. 
This race is said to range south to the middle Orinoco. A specimen 
collected at Puerto Ayacucho, January 3, 1930, and preserved in 
alcohol, may belong to this race, but it is not certainly identifiable in 
its present condition. 
CRANIOLEUCA VULPINA ALOPECIAS (Pelzeln): Northern Ruby-backed Spinetail 
Synallazis alopecias PruzELn, Sitzungsb. math. nat. Kl. Akad. Wiss. Wien, vol. 
34, 1859, pp. 101, 122 (Rio Branco). 
SPECIMEN COLLECTED 
lim. 9, Venezuela, Puerto Ayacucho, Upper Orinoco, January 5, 1930. 
This record helps to bridge the gap between the Amazonian and the 
previous Venezuelan ones (Orinoco Valley from the delta to beyond 
the falls of Maipures; upper Sarare). 
Two specimens were collected—Estado Bolivar, December 30, 1929— 
and were preserved in alcohol.
