^ C. i. intermedia Cory (Field Mus. N. H. Orn., i., p. 325 (1915), seems to be 

 non-separable. The average wing of his examples is the same as the measurement 

 of his type of ochracea ; the narrower band on the tail seems scarcely a reliable 

 distinction, while the white spotting on outer webs of primaries is a very variable 

 character. C. i. margaritensis Cory (T. c, p. 297), I am also unable to distinguish, 

 as examples with the paler under parts occur in the Merida district along with the 

 darker birds. His C. i. perplexa (t. c, p. 327) I am unable to distinguish, dark and 

 pale -breasted birds occurring together as I have before pointed out ; while C. i. 

 distincta (t. c, p. 297) is most certainly typical isabellinus _ the principal character, 

 the obsolete bars on inner webs of primaries, being present in Brit. Guiana examples.
