FAMILY TYRANNIDAE 593 



64.3-67.9 (66.1). tail 46.8-50.3 (48.8), culmen from base 13.5-15.2 

 (14.3, average of 4), tarsus 16.2-17.9 (17.0) mm. 



Females (9 from Chiriqui, Bocas del Toro, and Costa Rica), wing 

 60.0-64.9 (62.0), tail 41.7-46.5 (43.7), culmen from base 13.8-15.0 

 (14.2, average of 8), tarsus 16.0-16.9 (16.4) mm. 



Resident. Found locally in forested areas in the Tropical and Sub- 

 tropical zones, to 1800 meters elevation in western Chiriqui, and 

 western Bocas del Toro. 



From available records the nominate form of this species has its 

 principal distribution in Costa Rica, where Slud (Bull. Amer. Mus. 

 Nat. Hist., vol. 128, 1964, p. 274) recorded it as common on both 

 Caribbean and Pacific slopes though most abundant on the Caribbean 

 side. In western Chiriqui it is recorded mainly on the slopes of the 

 volcano, though not in abundance. The first report for Panama is 

 that of Salvin (Proc. Zool. Soc. London, 1870, p. 196) who listed 

 one taken by Arce. This specimen, now in the British Museum, is 

 labeled "southern slope Volcan de Chiriqui, 1870." Bangs (Proc. 

 New England Zool. Club, 1902, p. 351) listed seven collected by 

 W. W. Brown, Jr., near Boquete in March and April 1901. The 

 Monniche collection from this same region included male and female 

 (Blake, Fieldiana: Zool., vol. 36, 1958, p. 544). On Cerro Pando, 

 beyond El Volcan, I collected one March 3, 1954, and assistants of 

 Dr. Frank A. Hartman, three others in February and March 1956, 

 and February 10, 1960. From March 2 to 30, 1967, near Nueva 

 Suiza (below Cerro Punta) eight were banded and released by men 

 working under the direction of Horace Loftin. G. V. N. Powell listed 

 another there on December 21, 1968. 



Near the Rio Chiriqui Vie jo I saw one eating small berries in a 

 feeding tree. The few that I have observed in life moved quietly 

 through the undergrowth in the forest. 



The two specimens, a male and a "female," that Lawrence desig- 

 nated as his types, were both collected by J. Carmiol. The male, a 

 bird with the ninth primary only slightly narrowed, was taken at 

 Barranca February 26, 1866. According to Carriker (Ann. Carnegie 

 Mus., vol. 6, 1910, p. 335) Carmiol's locality under this name was on 

 the western slopes of Volcan de Poas. The female labeled "Dota" 

 (Santa Maria de Dota) in the mountain area, about 60 kilometers 

 southeast of San Jose, was collected January 20, 1864. While marked 

 "$" it is definitely larger than that sex, as with wing of 67.9 mm it 

 agrees fully in this dimension with males. The bird from Barranca, 

 an undoubted male, is here designated as the holotype.
