248 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



the nest was about 145 mm broad and the same in depth, with the 

 base about 300 mm across. The inner cup measured 90 mm across 

 by 50 mm deep. The nest contained two young, probably 3 or 

 4 days old. "They had black down, rather heavy for a passerine, and 

 the skin was black, matching the black nest material. The mouth and 

 gape were orange -yellow." 



The three specimens from Panama agree in darker coloration with 

 the type of chocoensis. The type, however, the only one recorded 

 from Colombia, with the wing 93.5, tail 28.2, culmen from base 24.1, 

 and tarsus 50.6 mm, except in tarsal length is smaller. Assignment 

 of the three from Panama is tentative, based on color, as possibly 

 they may represent a distinct larger race. 



HYLOPEZUS FULVIVENTRIS (Sclater) : Fulvous-bellied Ant-pitta, 

 Hormiguero Vientrileonado 



Grallaria julvivcntris P. L. Sclater, Proc. Zool. Soc. London, pt. 28, April 26, 

 1858, p. 68. (Rio Napo, Ecuador.) 



Rather small, of typical ant-pitta form ; dark above, white below 

 with buff or rufous breast streaked lightly with black. 



Description. — Length 125-150 mm; without rictal bristles. Adult 

 (sexes alike), crown and hindneck dull slate with the feathers 

 bordered narrowly with black ; lores and ring around eye cinnamon- 

 buff ; side of head below and behind eye dull buff ; blackish to brownish 

 olive above ; outer webs of primaries chestnut ; lower surface white, 

 except the breast, which is buff to cinnamon, lined narrowly with 

 dull black ; sides, flanks, under tail coverts, and tibiae rufous ; edge 

 of wing and under wing coverts cinnamon ; inner webs of wing

As a species these birds are found on the Caribbean slope from 

 southeastern Honduras and eastern Nicaragua through Costa Rica 

 and western Panama. They appear again in the eastern mountains 

 of the Republic, and continue in South America through western 

 Colombia to eastern Ecuador. In this area five geographic races have 

 been recognized, two of them found in Panama. They are little known 

 inhabitants of undergrowth in forests of the Tropical Zone.
