BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 47} 
Carriker’s arrangement of the Formicivora grisea and F. intermedia 
complex seems better than the older one he altered and is followed in 
this report, although it must be admitted that hondae does partly 
bridge the gap. However, inasmuch as orenocensis and rufiventris 
both occur at Puerto Ayacucho, it certamly seems better to regard 
them as specifically distinct. 
This series has already been published on by Carriker (Auk, 1936, 
pp. 316-317). 
An additional specimen from Puerto Ayacucho, taken January 3, 
1930, was preserved in alcohol. 
TERENURA SPODIOPTILA SPODIOPTILA Sclater and Salvin: Ash-winged Ant-wren 
Terenura spodioptila ScuatER and Savin, Ibis, 1881, p. 270, pl. 9, fig. 1 (Bartica 
Grove, British Guiana). 
SPECIMENS COLLECTED 
lad. 9, Brazil, Rio Cauabury, November 5, 1930. 
lim. o’, Brazil, Cucuhy, Rio Negro, February 8, 1930. 
lad. o’, Venezuela, Brazo Casiquiare, below Cafio Caripo, February 22; 1931. 
1 ad. o, Venezuela, Upper Orinoco, near Isla Temblador, February 25, 1931. 
It is unfortunate that no adult male was collected on either the Rio 
Cauabury or the Rio Negro, as it would have made more definite a 
comparison with the description of J. s. signata Zimmer, described 
from Mount Curycuryari, on the right bank of the Rio Negro. There 
is no chestnut on the lesser upper wing coverts of the immature male 
from Cucuhy (signata is said to have these feathers chestnut instead of 
gray as in spodioptila), and it seems better to call the specimen typical 
spodioptila. Furthermore, in support of this decision, it may be noted 
that the lower wing band (on the greater coverts) is as broad as in the 
two adult males from the Casiquiare and the upper Orinoco (whence 
Zimmer records T. s. spodioptila), while in the description of signata 
this wing band is described as narrower than in the nominate form. 
The female from the Rio Cauabury is assumed to be of the same sub- 
species as the Cucuhy male; no females have been available for 
comparison. 
The present race appears to be an addition to the known avifauna 
of Brazil. It is not listed by Pinto (Catalogo Aves do Brasil, pt. 1, 
1938, p. 490).
