FAMILY FURNARIIDAE 83 



olivaceous." In museum specimens the lower surface of the mandible 

 usually is dull huffy white. 



Measurements. — Males (10 from Costa Rica, Chiriqui, Veraguas, 

 and Code), wing 81.9-86.4 (83.6), tail 64.8-69.3 (67.2), culmen 

 from hase 22.4-27.0 (24.5), tarsus 20.0-21.8 (20.7, average of 

 9) mm. 



Females (10 from Costa Rica, Chiriqui, Bocas del Toro, and 

 Veraguas), wing 79.7-82.9 (80.8), tail 63.5-68.4 (65.7), culmen 

 from base 23.3-25.3 (24.3), tarsus 20.0-21.6 (20.8) mm. 



Resident. Rather rare on the Pacific slope in western Chiriqui, 

 Veraguas, and southern Code ; on the Caribbean side in Cocas del 

 Toro and northern Veraguas. 



In Panama this race is rather widely distributed in the Tropical 

 Zone, but nowhere has it been reported common. The first record 

 for the Republic is a male from Nata, Code, taken December 11, 

 1888, by H. T. Heyde and Ernesto Lux. Their original label has the 

 notation "open wood." This record, published by Ridgway (U.S. 

 Nat. Mus. Bull. 50. pt. 5, 1911, p. 200), was the basis for inclusion 

 of this race in Panama by Griscom and others. 



In Chiriqui. H. J. Watson took three at Bugaba, in October and 

 November. 1903. I collected a pair on February 23, 1955, on the 

 Ouebrada Candela, 5 kilometers east of Sereno on the Costa Rican 

 boundary, at 1125 meters in gallery forest, where they were in com- 

 pany with a scattered group of several kinds of small forest birds. 

 While most of the company were searching through leaves, mainly 

 on the outer branches, the pair of leaf-gleaners examined the 

 epiphytes on the tree trunks and larger limbs, digging out dead leaves 

 and other bits of trash in their search for food. One worked at one 

 airplant for some time, cleaning out the miscellany that had lodged 

 amid the leaves. Another record is of a female given to me by Dr. 

 F. A. Hartman. taken by one of his collectors February 11, 1960, in 

 heavy forest at 1525 meters on Cerro Pando, above the Rio Chiriqui 

 Viejo. Two were collected near Santa Fe, Veraguas, by R. R. Ben- 

 son, in February and March 1925. 



From the Caribbean side there is a specimen in the American 

 Museum of Natural History, taken by Horace Loftin at Almirante, 

 Bocas del Toro, October 17, 1965; and four males and two females 

 taken by Benson at the Rio Calovevora, eastern Boca del Toro, from 

 August 26 to September 14, 1926. This area seems to be the only one 

 where the race has been found in numbers.
