6 Messrs. Thayer and Bangs refer the birds from the mainland of Panama to " Myio- 

 bius nxvius nsevius" (= Myiophobus fasdatiis fasciatus), restricting the subspecific 

 term, furfurosus to the birds from Saboga and San Miguel islands; but it seems to me 

 that they agree much better with the latter than with Colombian specimens, which I 

 am not able to distinguish from examples of the species from other parts of South 

 America (excepting, of course, those from Argentina).
