 sula, Gaspe County) ; and southwestern Newfoundland (Tompkins).

 northern New Brunswick (Tabusintac, Chatham, and Edmundston) ; 

 northern Maine (probably Sourdnahunk Lake, and Moosehead

Winter range. — The winter home of the Philadelphia vireo is in 

 Central America from northern Guatemala (Volcan de Agiia and 

 Secanquim) through El Salvador (Mount Cacaquatique) ; and prob- 

 ably western Nicaragua; the higher portions of western Costa Rica 

 (Liberia, San Jose, Guayabo, and the valley of El General) ; to 

 western Panama (Volcan de Chiriqui, Cocoplum, and Altoc Cacao 

 on the Azuero Peninsula). A specimen from Cozumel Island, Mex- 

 ico, was recorded by O. Salvin in the Ihis for 1888 as taken in Janu- 

 ary "during the last two years." It was probably accidental at that 

 date.
