FAMILY COLUMBIDAE 1 5 



With a good series of C. nigrirostris now available from Panama, 

 it is evident that the pigeon listed currently as Columba chiriquensis 

 (Ridgway), known only from the type, is an individual of the present 

 bird. The indistinct barring on the hindneck, one of the supposed 

 differences, is found in several specimens of nigrirostris that I have 

 examined, and probably is an indication of immaturity. The purplish 

 cast on the dorsal surface of the type of chiriquensis also is duplicated, 

 and the wing measurement of 155 mm. is that of this species.

The range of Columba nigrirostris extends to northern Choco in 

 Colombia, where I have specimen records for Acandi and the head of 

 Rio Cuti on the eastern slope of the Serrania del Darien, below the 

 eastern end of Cerro Mali. To the north this species ranges through 

 Central America to southern Veracruz.
