These specimens do not differ from Qpper Amazonian skins. 



Salvin and other authors called this bird T. rujlcollis ex Spix. The fVniales of 

 7'. amaso/ticus and 3'. ci/iereicrps Pelz., however, are qnite identical in coloration, 

 dilfering only in size, and as Spix collected also on the Rio Negro where the latter 

 species is met with, his description and figure could refer with equal certainty to 

 the female of T. cinereiceps. Unfortunately the type does not any longer exist 

 in the Munich Bluseum, and I sec uo alternative but to drop the name rujlcollis 

 altogether in favour of those proiwsed by Sclater aud Pelzelu, about the application 

 of which there is not the slightest doubt.
