284 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



had the iris dark brown ; maxilla and tip of mandible black ; base of 

 mandible and bare skin between rami dull pink; tongue dull flesh 

 color. 



Measurements. — Males (14 from Chiriqui, Veraguas, and Los 

 Santos), wing 70.1-75.8 (72.4), tail 41.0-45.6 (43.2, average of 13), 

 culmen from base 22.7-26.6 (24.0) mm. 



Females (10 from Chiriqui, Veraguas, and Los Santos), wing 

 68.4-72.4 (70.0), tail 42.0-45.8 (43.7), culmen from base 23.8-26.7 

 (25.5 average of 9) mm. 



Resident. Fairly common locally in Chiriqui (Bugaba, El Banco, 

 San Felix), Veraguas (Puerto Vidal, Zapotillo, Sona, Paracote) and 

 Los Santos (Guanico Arriba, Tonosi, Ensenada Venado, Pedasi). 

 There are no records for the species between eastern Veraguas and 

 the Canal Zone, so that this population appears to be isolated by the 

 broad expanse of the savanna grasslands. 



I recorded them feeding at flowers of the guayabo, in flowering 

 trees in the mangroves. Others gleaned the bark of shrubs and 

 trees. 



Griscom, dependent on Hartert's brief description of saturatior 

 from Isla Coiba, placed these darker birds of the western mainland 

 with the Coiba race, but in this was in error. The race P. c. maculi- 

 cauda Griscom of Costa Rica resembles P. c. cuvierii in paler color, 

 but is less brassy green on the foreneck, breast, and sides, and usually 

 has the white tip on the outer rectrices less in extent. Also it is larger 

 (in this agreeing with furvescens) as shown in the following 

 tabulation : 



Males (8 from Costa Rica), wing 70.3-74.4 (72.4), tail 41.3-44.6 

 (43.2), culmen from base 22.2-25.1 (23.8) mm. 



Females (10 from Costa Rica), wing 68.0-71.7 (69.5), tail 41.8- 

 44.4 (42.9), culmen from base 23.0-26.8 (25.1) mm. 



PHAEOCHROA CUVIERII SATURATIOR (Hartert)

Characters. — Largest and darkest of the races; averaging darker 

 green above, and on the breast and foreneck; decidedly darker on 

 the lower breast and abdomen. 



Measurements. — Males (2 from Isla Coiba), wing 75.8, 78.7, tail 

 45.0, 45.5, culmen from base 24.7, 25.6 mm. 



Females (2 from Isla Coiba), wing 70.2, 74.1, tail 45.2, 46.7, culmen 

 from base 24.7, 25.9 mm.
