Immature, head black, becoming brownish on cheeks ; above fus- 

 cous ; under surface from nearly white in some individuals to 

 ochraceous in others, the paler ones with an indistinct whitish or 

 buffy ring on hindneck. 



An adult female, taken on Isla Coiba, had the following colors : 

 Iris orange ; base of maxilla below nostril, and base of mandible, 

 neutral gray; rest of bill black; cere dusky neutral gray; edge of 

 eyelids honey yellow; rest of the bare skin about the eye, and on 

 the loral area, dull yellowish green ; tarsus and toes yellow ; claws 

 black. 



Measurements. — Males (5 from Panama and northern Colombia), 

 wing 202-211 (207), tail 166-173 (170), culmen from cere 14.6-15.5 

 (14.9), tarsus 59.9-64.1 (61.7) mm. 



Females (5 from Panama and northern Colombia), wing 234-240 

 (237), tail 177-189 (184), culmen from cere 16.7-19.5 (18.1), tarsus 

 67.3-69.3 (68.4) mm. 



Resident. Rare; widely distributed, but not recorded from Los 

 Santos and Herrera on the eastern side of the Azuero Peninsula, 

 Code, or San Bias. Found on Isla Coiba. 



This is another forest species, a hunter of small birds, that may be 

 more common than appears from the few seen, since a fair number 

 have been collected over a period of one hundred years. 



In Chiriqui it has been taken from Boquete across the southern 

 slopes of the volcano to Bugaba, near the Costa Rican boundary, as 

 well as near San Felix in the eastern part of the province. Salvin 

 (Proc. Zool. Soc. London, 1870, p. 215) received skins from Arce 

 shot at Chitra and Calovevora in Veraguas. These are records that 

 may not be duplicated as most of the lowland forest cover in these 

 provinces now is gone. At Paracote, Aldrich (Scient. Publ. Cleve- 

 land Mus. Nat. Hist., vol. 7, 1937, p. 42) shot an immature male as 

 it crossed an open field with direct flight, alternately beating the wings 

 and gliding. Lawrence received one from McLeannan, taken some- 

 where along the Panama Railroad, and there is one in the National 

 Museum from the same source marked Frijoles. Imhof (manuscript 

 notes) recorded one in the Madden Forest Reserve May 31, 1942. In 

 Bocas del Toro, von Wedel collected one (Peters, Bull. Mus. Comp. 

 Zool., vol. 71, 1931, p. 311) near Almirante, and Monniche one at 

 Cedral near 1,500 meters elevation on the Holcomb Trail. Loye Miller 

 secured one near Cricamola on August 31, 1936 (specimen at the 

 University of California in Los Angeles). 



The only records for the eastern area are of a male taken at San 

 Antonio on the lower Rio Bayano east of Chepo (Havemeyer collec-
