Messrs. Salvin and Godman compare this species with IT. grisens and 

 JL 'blcolor^ of South America, and state that "from C. caj?lstratus 

 . . . the new bird is so different that comparison is unnecessary." It 

 is unfortunate they did not state in just what particulars of coloration 

 it differs from the last-named species.
