have the gray anterior and the brown posterior abdominal areas 
separated by a whitish band. A few of the present specimens vaguely 
suggest such a band but are nearer to typical tenebrosa than to the 
coastal race pallida. A slightly larger, pale-bellied race, brasiliensis, 
occurs in southeastern Brazil. 
A set of two eggs was collected at Chapazon, January 31, 1931.

The southward limit of the range of this race is unknown. It must 
be rare, if not absent, on the Upper Rio Negro, or the expeditions 
would have collected some specimens, judged by the fine series they 
took farther north. Pinto (Rev. Mus. Paulista, vol. 22, 1937, pp. 321) 
records aurantiicinctus from Barcellos, Rio Negro, with a query as to 
whether the specimen collected there by Natterer may not really 
have been C. a. hypochondriacus Chapman, which ranges to the Lower 
Rio Negro. Judged by our present series from Séo Gabriel southward 
to Santa Isabel, it would certainly seem that Barcellos birds would be 
not hypochondriacus but transilens. 
From the specimens studied and from the literature it seems that 
intermedius Berlepsch and Hartert is not separable from aurantiicinc- 
tus. If the two were to be recognized the present series, while partly 
from the range of each, would have to be called intermedius, as none 
of the birds have any orange or cadmium edgings on the feathers of 
the rump or flanks.
