270 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



PHAETHORNIS SUPERCILIOSUS CASSINII Lawrence 



Phaethornis Cassinii Lawrence, Ann. Lye. Nat. Hist. New York, vol. 8, 1866, 

 p. 347. (Turbo, Antioquia, Colombia.) 



Characters. — Averaging slightly smaller with shorter tail ; slightly 

 darker, more definitely green on the back ; crown slightly blacker ; 

 rump and upper tail coverts more cinnamon-buff. 



A male shot at Puerto Obaldia, San Bias, February 16, 1963, had 

 the iris dark brown ; base of mandible rather light bright brown ; rest 

 of bill black; tarsus and toes brownish neutral gray; claws fuscous- 

 black. 



Measurements. — Males (10 from Darien), wing 58.1-61.2 (59.9), 

 tail 59.0-64.4 (61.5), culmen from base 37.0-40.5 (38.8) mm. 



Females (10 from eastern Panama Province, Darien, and Choco), 

 wing 58.0-61.5 (59.2), tail 60.0-62.9 (61.5), culmen from base 36.8- 

 42.0 (38.7) mm. 



Weight, 1 female, 6.15 grams (Hartman, Auk, 1954, p. 468). 



Resident. Locally common in the Tropical Zone in eastern Pan- 

 ama in forested areas; eastern sector of Panama Province (Cerro 

 Azul, Chiman, Charco del Toro), Darien (Cerro Sapo, Rio Chucuna- 

 que at the mouth of the Sucubti and of the Tuquesa, Boca de Paya, to 

 550 meters on Cerro Pirre, Jaque, Rio Jaque), and San Bias (Man- 

 dinga, Perme, Ranchon, Puerto Obaldia). 



The records for Cerro Pirre include 2 that I collected on the upper 

 Rio Seteganti February 7, 1961, at about 450 meters, and 1 secured by 

 Goldman near Cana at 550 meters. I regard both these points as 

 within the upper edge of the Tropical Zone. 



The male taken by the anthropologist John L. Baer at the mouth of 

 the Rio Sucubti on April 13, 1924, was his last specimen. As the label 

 is not in his handwriting apparently he was seriously ill at the time. He 

 died at Ada May 28, and was buried there "in the coral sand under 

 a clump of coconut trees commanding a beautiful view." (Marsh, 

 White Indians of Darien, 1934, p. 188.) 



This race ranges in Colombia in the lower Atrato Basin to northern 

 Choco ( Unguia, Acandi) and the eastern side of the Golfo de Darien 

 in extreme northern Antioquia (Necocli, Turbo). 



PHAETHORNIS ANTHOPHILUS (Bourcier) : Black-cheeked 

 Hermit, Ermitano Mejillinegro 



A green-backed hermit, grayish white on the under surface, with 

 streaked throat ; side of head broadly black.
