FAMILY TROCHILIDAE 373 



from 31.0-33.6 mm., are intermediate between those of adults of the 

 two sexes. 



Known in Panama from 1 specimen from Cerro Pirre, Darien, 

 collected at Cana April 13, 1938, by Oliver Pearson. This skin, in the 

 Academy of Natural Sciences in Philadelphia, is immature. It is 

 whiter on the throat, foreneck, and upper breast than usual in this 

 species. The measurements are as follows; wing 37.6, tail 19.0, 

 culmen from base 15.2 mm. It is marked as male, which if accurate 

 may indicate that it represents a local race, as the wing is longer 

 than in immature males of typical A. h. heliodor from Colombia of 

 similar stage of plumage.
