Todd (Ann. Carnegie Mus., vol. 30, 1943, pp. 13-14) has recently 
studied the geographic variations of this species with results with 
which the material seen in the present connection is in good agreement. 
This material has been limited to two races—tamatia and hypnaleus.

Pinto (Rev. Mus. Paulista, vol. 22, 1937, p. 315) considers birds 
from the Rio Negro as N. r. cineracea, but it would seem that they are 
better referred to duidae. Todd (Ann. Carnegie Mus., vol. 30, 1943, 
p. 18) has extended the known range of duidae south to Tonantins on 
the north bank of the Amazon.
