BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 473 
The specimen is molting the wing feathers. 
Material has not been available to investigate the status of C. n. 
atratus Todd or C. n. maculosa (Sclater), but inasmuch as most recent 
authors appear to agree in referring to nigricans binomially the same 
method has been followed here.

Apparently this form is the one found along the Rio Negro; also 
it has a wide range in the lowlands of the great Amazonian 
forest from Cayenne through southern Venezuela to the Casiquiare 
to Colombia, eastern Ecuador, eastern Peru, and northern Bolivia.

Although this bird is known from southern Venezuela (Mount 
Duida and the Upper Orinoco) the present expedition failed to find it 
there, but only in the adjacent Rio Negro country of Brazil. It oc- 
curs south as far as Séo Gabriel, on the left bank of the Upper Rio 
Negro, but at Tabocal, on the right bank, not very far to the southeast, 
another subspecies, M. m. ardesiacus Todd, takes its place.
