The scarlet-crested tanagers inhabiting the Upper Orinoco Valley 
have been the subject of divergent opinions by investigators. Chap- 
man (Bull. Amer. Mus. Nat. Hist., vol. 55, 1926, p. 680) found that 
eight males from Maipures and Suapure, Upper Orinoco, had much 
larger bills and slightly smaller and deeper crests than a series from 
eastern Ecuador and from Cayenne. He wrote that he considered 
these Orinoco birds separable, but in default of Bogoté specimens of 
“cristatellus’’ Sclater, he was not able to decide if that name should 
be used or a new one coined for them. Hellmayr (Catalogue of the 
birds of the Americas, pt. 9, 1936, p. 327, footnote), on the other hand, 
found that birds from the Caura Valley, Venezuela (east of the Upper 
Orinoco!), and the Upper Rio Negro could not be satisfactorily sep- 
arated from a series of ‘“Bogota” skins (cristatellus)! Unfortunately 
the comparative material available for study in the present connection 
does not permit me to decide between these two opinions. Inasmuch 
as Hellmayr apparently had the critical material lacking to Chapman, 
and also topotypical Cayenne birds, I follow the former’s conclusions.
