 as the head, with lower margin of mandible dull white, rest olive or 

 black. 



Measurements. — Males (10 from Chiriqui, Bocas del Toro, and 

 Costa Rica), wing 102.9-111.8 (107.7), tail 86.6-106.2 (94.6), culmen 

 from base 20.9-24.4 (22.4, average of 8), tarsus 25.9-28.0 (27.1) mm. 



Females (10 from Chiriqui and Costa Rica), wing 96.0-101.0 

 (98.0), tail 84.8-93.5 (86.9), culmen from base 20.6-28.5 (24.0), 

 tarsus 25.1-26.7 (25.8) mm. 



Resident. Rare and little known in the higher mountains of western 

 Panama from Chiriqui and Bocas del Toro to eastern Veraguas. 



The first report for Panama is by Salvin (Proc. Zool. Soc. London, 

 1870, p. 192) of one forwarded by Arce, collected on the Cordillera 

 de Chucu, Veraguas, now in the British Museum, a male with the 

 date 1869. A second of the same sex in that collection, also taken 

 by Arce, is marked "Calobre," Veraguas, 1870. The locality given, 

 which is in the lowlands east of San Francisco, is questionable, as 

 the bird is known only from the mountains. The species was re- 

 ported next by Bangs (Proc. New England Zool. Club, vol. 3, 1902, 

 p. 44), who received four specimens collected by W. W. Brown, Jr., 

 on the slopes of the mountains above Boquete, at elevations of 1200 

 to 3125 meters. Griscom (Amer. Mus. Nov., no. 141, 1924, p. 4) took 

 a male at 1825 meters on Cerro Flores, March 17, 1924. During 

 the period between 1932 and 1952 ToUef B. Monniche secured three, 

 one at Camp Cilindro at 1580 meters on the Holcomb Trail, across 

 the divide in Bocas del Toro, and two on Cerro Copete, in Chiriqui, 

 at above 3000 meters on the volcano (Blake, Fieldiana: Zool., vol. 36, 

 1958, p. 530). The U.S. National Museum has one specimen, a 

 female, taken February 3, 1953, at 2133 meters on Cerro Copete, re- 

 ceived from Dr. Frank A. Hartman. Dr. E. Tyson informs me that 

 he saw these birds in 1965 at 2300 meters elevation on the western 

 slopes of Volcan Baru. Dr. Eisenmann has found it at 2100 meters 

 on the old trail from Cerro Punta to Boquete, working among the 

 epiphytes on high branches 30 meters or more above the ground.
