RENDAHL, BIRDS FROM THE PEARL ISLANDS. 37 



This subspecies is very nearly allied to E. ch. chiriquensis 

 (Lawr. ) from Panama and South America, dif f ering according 

 to Thayer and Bångs only in average characteristics. The 

 upper parts are very slightly dusker and less olivaceous in 

 color, wings and tails slightly shorter, bill averaging slightly 

 longer.

BOVALLIUS. 



In comparison with M. /. fasciatus of South America 

 Thayer and Bangs described the bird of the Pearl Islands 

 as a separate subspecies on account of its more strongly buffy 

 under parts, less distinctly striped breast, and paler upper 

 parts. Mr. Ridgway found these characters also distinguishing 

 the birds from the mainland of Panama, these birds being 

 therefore together with those from the Archipel to be re- 

 ferred to M. /. furfurosus in opposition to those of Colombia 

 and other parts of South America, which belong to true M. f. 

 fasciatus.
