FAMILY PHASIANIDAE 329 



foreneck, and breast black, the breast barred narrowly with white; 

 throat and upper foreneck white; abdomen dull fuscous with faint 

 tippings of cinnamon ; sides, flanks, tibia, and under tail coverts like 

 the upper surface but brighter brown ; shorter under wing coverts like 

 back, longer ones fuscous like flight feathers. 



There is much variation in color in which the upper surface may 

 be blacker, and the white of the throat much reduced or nearly 

 absent; or both upper and lower surface, including much of the 

 breast, are brighter brown. The supposed species smithianus was 

 described from birds in the blacker phase. 



Immature birds have the tip of the bill cinnamon to huffy brown, 

 while in the adult it is black. 



Measurements. — Males (10 from Panama and Costa Rica), wing 

 117.9-130.1 (124.6), tail 44.2-58.6 (49.1), culmen from base 14.7-17.5 

 (16.3), tarsus 44.5-48.0 (45.9) mm. 



Females (7 from Panama and Costa Rica), wing 125.0-129.7 

 (127.2), tail 46.2-50.2 (48.2), culmen from cere 14.6-17.2 (15.6), 

 tarsus 43.2-45.5 (44.1) mm. 



Resident, Rare, in the subtropical zone of Chiriqui, Veraguas, and 

 Bocas del Toro; recorded from 1,350 to 1,600 meters elevation. 



This distinct species was named by Salvin from a female taken 

 by Arce in the Cordillera de Tole, which is in eastern Chiriqui under 

 present political boundaries, though recorded originally from 

 "Veragua." Arce later sent Salvin (Proc. Zool. Soc. London, 1870, 

 p. 217) a specimen from Calovevora, Veraguas, and also one to 

 Gould from Chitra (Salvin and Godman, Biol. Centr.-Amer., vol. 3, 

 1903, p. 311). In western Chiriqui Bangs (Proc. New England 

 Zool. Club, vol. 3, 1902, p. 22) received specimens taken by W. W. 

 Brown, Jr., near Boquete and also on the Caribbean slope beyond, 

 which would place them in Bocas del Toro. In the American Museum 

 of Natural History collection there is one specimen from Boquete, 

 taken by Watson, another collected by Arce at Chitra, and two taken 

 at this same point at over 1,000 meters, December 30 and 31, 1925, 

 by Benson. Monniche (Blake, Fieldiana: Zool., vol. Z6, 1958, p. 508) 

 secured a male at Camp Cilindro on July 14, 1933, and a female at 

 Camp Holcomb on June 26, 1933, both on the Caribbean side of the 

 divide in Bocas del Toro. These last are the latest records for the 

 species in Panama. 



There is a skin in the U. S. National Museum collected by Heyde 

 and Lux labeled "Nata, Code," a lowland locality where this species 

 would not be found. It is possible that the collectors secured it in 

 a journey that they made into the subtropical zone beyond La Pintada.
