Characters. — Differs from intermedins mainly by dark gray of un- 

 dersurface; from iungens by greater extent of black on side of throat 

 and across breast.

 Nicaragua), wing 99.0-104.0 (101.8), tail 91.0-102.4 (96.6), culmen 

 from base 21.0-23.1 (21.9), tarsus 24.4-26.7 (25.4) mm.

Resident. Known in Panama only from the Almirante Bay region 

 of Bocas del Toro, where I have found it at Almirante and Changuinola. 

 It has also been collected at Guabo and Cricamola (Peters, Bull. Mus. 

 Comp. Zool., vol. 71, 1931, p. 338). Beyond Almirante Bay, it ranges 

 north along the Caribbean slope to Chiapas in southern Mexico. Near 

 Almirante, I shot 1 from a little group at the edge of a banana plantation 

 on Western River.
