Specimens from the islands of Abaco, New Providence, and Green Cay, and part 

 of th(jse from Rum Cay, Bahamas, evidently represent resident birds, since they dif- 

 fer from all examples from the United States in decidedly larger bill and much 

 broader yellov/ superciliary stripe, the latter encroaching anteriorly on the sides of 

 the forehead. Specimens from other Bahama islands, including most of those exam- 

 ined from Rmn Cay, are not distinguisliable from United States examples, and with- 

 out much doubt are winter visitors from the latter country. T'ntil more is known 

 of the Bahama resident birds, however, I do not venture to separate them sub- 

 specilicaiiy.
