242 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



some, dusky ; inner wing feathers edged on inner web with cinnamon- 

 buff. 



Immature, with feathers of breast more heavily edged with dusky, 

 producing more definite Hues than in the adult. 



As a species this small ant-pitta is found from Costa Rica and 

 Panama to northern South America where it is known in the Andes 

 from Colombia south to Bolivia. Two of the eight subspecies cur- 

 rently recognized are found in the Republic of Panama. These birds 

 are poorly known, with very little recorded concerning them.

Characters. — Upper surface faintly grayer, with the crown nearly 

 uniform in shade with the back; bill averaging very slightly smaller. 



Measurements. — Males (5 from Chiriqui, Veraguas, and Costa 

 Rica), wing 62.8-65.5 (64.1), tail 20.8-23.6 (22.4), culmen from 

 base 14.9-15.6 (15.2). tarsus 20.8-22.0 (21.5) mm. 



Females (7 from Chiriqui, Bocas del Toro, and Costa Rica), wing

Resident. Known from a few records in the mountains of Chiriqui 

 and Bocas del Toro, ranging east to Chitra and Calovevora, Veraguas. 



The first record for Panama is a male from the Cordillera de Tole 

 taken by Enrique Arce in 1866, now in the British Museum. Salvin 

 in his second paper on Arce's specimens (Proc. Zool. Soc. London, 

 1870, p. 196) listed another from Chitra. This latter bird is not 

 present now in the Salvin-Godman collection in London. I have seen 

 the one from Calovevora, now catalog number 16427 in the Natur- 

 historische Museum in Vienna. This bird, formerly mounted for 

 display, now in poor condition with the bill broken, is labeled "$, 

 Calovevora. Veragua, 1869, Arce." W. W. Brown, Jr., collected a 

 female at 1220 meters on the Caribbean slope in Bocas del Toro on the 

 trail from Boquete to Chiriqui Grande. A male in the U.S. National 

 Museum was collected for Dr. Frank Hartman at 1375 meters near 

 El Volcan, Chiriqui, February 22. 1949. Another, a female, was 

 taken at 650 meters on the upper Rio Changuena, September 12, 

 1961, by R. Hinds of the Gorgas Laboratory.
