SPECIMENS COLLECTED 
1 ad. o&, Brazil, Rio Negro, February 8, 1930. 
lad. 2, Brazil, Sio Gabriel, Rio Negro, December 27, 1930. 
1 im. -, Venezuela, Cerro Yapacana, Upper Orinoco, April 17, 1931. 
The female is larger and more rufescent than the male and has the 
top of the head darker, more blackish. The young bird has the 
feathers of the breast and lower throat and sides of the neck tipped 
with wedge-shaped white marks edged with black on their proximal 
sides, the feathers of the upper and lateral abdomen with the white 
tips more elongated less wedge-shaped and with no black edging; the 
upper wing coverts also have small medioterminal white spots; the 
greater upper wing coverts and the scapulars are tipped with olive- 
brown, the basal part of this terminal area being lighter and yellower, 
proximally broadly bordered with fuscous to fuscous-black. 
The pileated tinamou occurs throughout the areas traversed by the 
collectors.

‘“‘Le Tinamou varié’”’? Daubenton, Planches enluminées..., pl. 828: Cayenne). 
SPECIMENS COLLECTED

The two specimens taken at Cerro Yapacana had the gonads en- 
larged and in active condition when collected. 
The Brazilian specimen is quite different from the other two, and 
agrees with Todd’s description (Proc. Biol. Soc. Washington, vol. 50, 
1937, p. 176) of two birds from the Caura River, Venezuela, and one 
from Obidos, Brazil. ‘Instead of being black, above, narrowly barred 
with buffy, they are decidedly rufescent (near Brussels brown), 
barred and mottled with black; the buffy bars are scarcely obvious, 
except on the wing-coverts; the upper tail coverts have black bars 
separated by olive brown interspaces each having a median transverse 
rufescent buffy line . . . Since we have also a perfectly typical adult 
(variegatus) from Obidos these three odd birds must represent either a 
color-phase, a stage of plumage not fully mature, or another species 
altogether. They certainly look different enough to justify the latter 
alternative, hard as it is to accept...” Todd’s birds showed 
traces of immaturity—some whitish spots on the upper wing coverts; 
the present example shows none, and it therefore decreases the likeli-
