FAMILY TROGONIDAE 415 



nest as one that "is open and exposed." On March 10, 1961, I col- 

 lected a set of 2 near the Candelaria Hydrographic Station on the 

 Rio Pequeni, Panama. The site was an old woodpecker hole 4 meters 

 from the ground in a dead stub that stood in fairly open woodland, 

 on the summit of a steep-sided hill. Since most of the front wall 

 of the cavity had broken away the eggs were clearly visible as 

 they rested on the bed of bits of wood, soft from decay, in the bottom. 

 When the nest was found the male was incubating. When I came 

 to photograph and collect the set the following day the female 

 covered the 2 eggs. These were slightly incubated. They are very 

 faintly creamy white, in shape between subelliptical and oval, with 

 measurements of 28.8x22.3 and 29.5x22.8 mm. A single egg in 

 the British Museum collection, taken February 24, 1898, at Pozo 

 Azul de Pirris, Costa Rica, is white, with slight gloss, elliptical in 

 form, with measurements of 28.1 X 22.6 mm. 



The race tenellus is found from southeastern Honduras through 

 Nicaragua, Costa Rica, and Panama to northern Choco (Unguia, 

 Acandi) in northwestern Colombia. The male of the form of western 

 Colombia, T. r. virginalis, has the central rectrices green. The species 

 ranges widely through northern South America.
