BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 483 
These birds bear out the characters of dissors as stated by Zimmer 
(cit. supra). The race is known from the Upper Orinoco area, the 
Casiquiare and the Rio Negro to southeastern Colombia and to the 
Lower Rio Madeira in northwestern Brazil. 
GRALLARIA VARIA CINEREICEPS Hellmayr: Ash-headed Ant-pitta 
Grallaria varia cinereiceps Hetumayr, Verh. zool.-bot. Ges. Wien, vol. 53, 1903, 
p. 218 (Marabitanas, Rio Negro). 
SPECIMENS COLLECTED 
1 ad.-, Brazil, Serra Imeri, near Salto do Hu, Venezuelan border, December 5, 
1930. 
Lad. 6, Venezuela, Brazo Casiquiare, mouth of Cafio Atamoni, February 6, 1931. 
As far as I have been able to ascertain from literature these are the 
first specimens of this race to be taken since the formerly unique type 
(female). Their measurements are as follows: ad. o& —wing 115.2, 
tail 39, culmen from base 30, tarsus 54.1 mm.; unsexed adult—wing 
116.2, tail 39, culmen from base —, tarsus 50 mm. The unsexed bird 
has the chin and upper throat duskier and the small flecks on the 
upper abdomen also duskier than in the male. 
These specimens agree with the characters of cinereiceps—bright 
ochraceous underparts, rufous-brown throat and foreneck (with the 
variation noted above), and rufescent sides of head. The back, 
however, is not russet brown as in the description of the type, but 
more olivaceous—dark Dresden brown. 
GRALLARIA MACULARIA DIVERSA Zimmer: Napo Spotted Ant-pitta 
Grallaria macularia diversa Zimmer, Amer. Mus. Nov., No. 703, 1934, p. 19 
(Puerto Indiana, Rio Amazonas, mouth of Rio Napo, Peru). 
SPECIMENS COLLECTED 
1 ad. o, Venezuela, Brazo Casiquiare, below mouth of Rio Pacila, February 
11, 1931. 
This species is one of the few in which the Rio Negro birds are 
different from those of the Casiquiare and Upper Orinoco. The present 
form, ranging from northeastern Peru, north of the Amazon, eastward 
and northeastward to the Casiquiare and the vicinity of Mount 
Duida, is more brownish, less olivaceous above, with the shaft streaks 
of the mantle less noticeable, than in G. m. paraensis, which occurs 
from the Lower Amazon west to the right bank of the Middle Rio 
Negro. The species has not been found as yet in the gap between the 
Middle Rio Negro and the Casiquiare.
