b Capita shelleyi Dalmas, Bull. Soc. Zool. France, 1900, 175 (Napo, e. Ecuador). 

 An adult male from Napo in the collection of the American Museum of Natural History 

 agrees with Dalmas' description except that the median portion (broadly) of the 

 breast and upper abdomen are tawny-orange.

1 am not at all sure that the birds from northwestern Colombia (San Antonio, Rio 

 Call) really belong to E. b. sequatorialis, not having been able to compare them with 

 specimens from western Ecuador.
