This specimen differs from a series of true li. olicace/is e.\ Bahia and Uio in its 

 much smaller size * and in having rather narrower and paler fnlvous margins to the 

 upper wing-coverts. Blost proliably it represents an nndescribed subspecies, but 

 I do not like to name it from a single specimen. The species has not before been 

 recorded from tlie Lower Amazon.
