FAMILY COLUMBIDAE 2.J 



wing, black. In the several northern subspecies these areas are almost 

 entirely cinnamon, with some mixture of black or dusky only in the 

 under wing coverts and on the tips of the wing feathers. Two geo- 

 graphic races are found in Panama. 



This species and others have been listed currently in a separate 

 genus Cohimbigallina (formerly called Chatnaepelia) . Examination 

 of structural details, including the skeleton, shows no trenchant points 

 of difference from the ground doves of South America of the genus 

 Columbina. It seems proper, therefore, to merge these two groups 

 under the older name Columbina, as proposed by Goodwin (Auk, 

 1959, pp. 512-513). 



It should be noted that the ruddy ground-doves included in the 

 species talpacoti have a narrow line of small feathers on both inner 

 and outer sides of the tarsus. In the passerina group of forms, and in 

 Columbina picui, this feathering is shorter, and is confined to the inner 

 side of that part of the leg.

Characters. — Male, darker, duller brown above, especially on the 

 wing coverts; female, somewhat paler, grayer on the lower surface,

 1962, had the iris reddish orange; edge of the eyelids Marguerite 

 yellow ; bare skin around eye dull neutral gray ; cere and adjacent area 

 of maxilla fuscous-brown ; rest of maxilla and tip of mandible dusky 

 neutral gray ; basal part of mandible dull greenish gray ; gape and pos- 

 terior half of the border of the mouth faintly honey yellow ; tarsus and 

 toes dull light pink ; claws dark brown. Another male, collected at 

 Puerto Armuelles, Chiriqui, February 24, 1966, had the iris very pale 

 orange-yellow ; edge of eyelids pale dull Marguerite yellow ; cere and
