Negro, and Guiana in size and coloration. Two males and three females from 
Eastern Brazil (Rio de Janeiro and Bahia) have longer wings and tail.

other synonyms are strictly applicable to the South-East Brazilian race.

The adult male is nearly uniform black both above and below. The two 
specimens obtained by Natterer near Borba and at the Serra Carauman are duller, 
sooty blackish underneath, and the former has the feathers of the rump as well

examples from Salto Girao, but in the series forwarded for my inspection by 
Dr. Lorenz this locality is not represented.
