Sittasoiiius levis Bangs, Proc. New England Zool. Club, vol. 3, January 30, 1902, 

 p. 46. (Boquete, Chiriqui, Panama.)

A male taken near El Volcan, Chiriqui, March 15, 1965, had the iris 

 dark brown ; maxilla fuscous-brown ; mandible dull neutral gray ; 

 tarsus brownish gray ; toes fuscous ; claws fuscous-black. 



Measurements. — Males (14 from western Chiriqui), wing 75.1- 

 83.3 (80.0), tail 71.3-78.1 (74.8, average of 13), culmen from 

 base 16.0-17.8 (16.9), tarsus 17.6-18.4 (18.0) mm.

Three collected by Mrs. M. E. Davidson, January 3-14, 1932, on 

 the ridge called Chame south of Cerro Flores, loaned for examina-

 Cerro Flores itself (1100-1160 meters) by Griscom and Boulton, 

 March 5-13, 1924, are identified as this race, the most eastern records. 

 To the west as noted above I recorded it at Sereno on the boundary 

 with Costa Rica.
