252 BIRDS OF THE REPUBLIC OF PANAMA — PART 3 



form the eggs are subelliptical with the measurements 26.3 X 20.2 and 

 25.7x20.0 mm. 



In a detailed account of this race in southwestern Costa Rica, 

 Alexander Skutch (Pac. Coast Avif., no. 35, 1969, pp. 271-274) 

 described their nests as placed in heavy forest in a tangle of vines or a 

 bush from half a meter to a little over a meter and a half from the 

 ground. Two examined were merely small platforms of twigs and 

 dried leaves, with a leafy depression in the top for the eggs. A third 

 was a thin-walled cup, built apparently by another passerine of 

 medium size, and abandoned. The ant-pitta had placed a few leaves 

 for a lining and then used it for its own eggs. Both parents incubate ; 

 in one instance one on the nest "apparently the male sang repeatedly, 

 while covering the eggs." Two eggs formed the set, in color "light 

 gray, heavily and coarsely mottled with dark brown, which almost 

 obscured the ground color on the thick end of some." In one nest the 

 eggs measured 26.2x20.6 and 27.0x21.4 mm. One egg in another 

 measured 26.2x20.6 mm. The young at hatching have no trace of 

 down on the dark skin. 



George K. Cherrie when he described this bird was employed 

 as taxidermist and ornithologist in the Museo Nacional of Costa Rica. 

 He named it for Don Joaquin Lizano, Minister of State of the 

 Republic of Costa Rica (born in Heredia, Costa Rica, in 1823, died 

 May 28, 1901), "to whom so much is due for the material advance- 

 ment and intelligent progress of various institutions of the country, 

 including especially the Museo Nacional."
