 (22.7), tarsus 14.2-14.9 (14.5) mm.

Resident. Common on the Caribbean slope in the tropical lowlands 

 from central Bocas del Toro (Chiriqui Grande), northern Code 

 (Cascajal) and the lower Chagres Valley (Juan Mina to Gatun) in 

 the Canal Zone, east through eastern Colon (Portobelo) and all of San 

 Bias (Mandinga, Armila, Puerto Obaldia) ; crossing to Darien on 

 the Pacific side in the Tuira Valley (Boca de Paya, Pucro), to range 

 eastward (through Garachine, Jesucito, Jaque) to Colombia; to 550 

 meters elevation on Cerro Pirre (Cana). 



In addition to the range as outlined there is one report from western 

 Panama that appears to be erroneous. Gould (Mon. Trogonidae, 

 1875, pi. [22] and text) in his account of chionums included a note 

 from Salvin which mentioned specimens collected by McLeannan in 

 what is now the Canal Zone, and said further that the bird "does not 

 seem to extend its range into Central America beyond the railway 

 ... as our collector Arce did not meet with it in the district of Vera-
