Adult female.— hength (skins), 138-171 (156); wing, 73.5-84.5 

 (77.1); tail, 64-76.5 (70.1); exposed culmen, 10-12.5 (11.3); tarsus, 

 18.5-21 (19.6); middle toe, 11-13 (11.7).« 



o Thirty specimens. 



I am not able to separate the Antillean from the continental series, but they are 

 mostly in worn or otherwise poor plumage, so that satisfactory comparison can not be 

 made; but they certainly are not the same as E. m. flavogastra of South America, to 

 which they have been referred. 



Most of the specimens from Saboga Island, Bay of Panama, and some specimens from 

 the vicinity of Panama City have the color of the upper parts paler and very much 

 grayer than others, even more so than E. m. flavogastra, and it is possible they may 

 represent a form worthy of recognition.
