The Altagracia, Caicara and Angostura specimens agree with others from 

 Pto. Cabello in Mus. H. v. B. The males from Venezuela differ from the males 

 from Surinam and Cayenne in Mus. H. v. B. by having the white feathers of the 

 crest more largely tipped with black, the white being consequently more concealed ; 

 also in the under parts of the body being much whiter (the black bars there being 

 much narrower), and by the white bands on the tail feathers being larger, more like 

 spots, and not so linear as in trae doliatus. 



The markings on the throat (in the males') are somewhat more longitudinal 

 in this form than in typical doliatus. This form seems to be widely spread in 

 Venezuela, and occurs also in the Venezuelan Andes, where another species, 

 Tkamnophilus bricenoi Hart., Nov. Zool. 1898 p. 220, PI. IV., is also found.
