FAMILY TYRANNIDAE 541 



Measurements. — Male (1 from Costa Rica), wing 53.0 tail 49.3, 

 culmen from base 11.9, tarsus 17.5 mm. 



Females (3 from Costa Rica and Veraguas), wing 49.6-52.7 

 (50.7), tail 42.8-48.3 (45.8), culmen from base 10.9-11.7 (11.2), 

 tarsus 15.6-16.5 (15.9) mm. 



Resident. Rare ; recorded from the mountains of Veraguas. 



The species in its nominate form was described from two specimens 

 now in the British Museum (Natural History), the type from Chitra 

 on the Pacific side, and another from Calovevora on the Caribbean 

 slope, both collected by Enrique Arce, in 1868. It is known also from 

 the Caribbean slope of Costa Rica, where Ridgway secured a female 

 at Guayabo, March 9, 1908. There is also a male in the British 

 Museum taken at Carrillo, November 17, 1898, by C. F. Underwood. 

 Slud (Bull. Amer. Mus. Nat. Hist., vol. 128, 1964, pp. 266-267) 

 found it at several localities in that country "apparently restricted to 

 the wettest portions of the cool subtropical belt." He recorded it as 

 traveling actively with bands of small birds, where its mannerisms 

 suggested those of a small warbler. Attention often was attracted to 

 it by its lively calls. 



PHYLLOSCARTES SUPERCILIARIS PALLORIS (Griscom) 



Mecocercxilus supcrciliaris palloris Griscom, Occ. Pap. Boston Soc. Nat. Hist., 

 vol. 8, February 21, 1935, p. 200. (Tacarcuna village site, base of Cerro 

 Tacarcuna, Darien, Panama.) 



Characters. — Duller in general coloration above ; crown darker ; 

 back dull olive-green ; paler on lower surface, both in the gray of 

 breast and the yellow of the abdomen. 



Measurements. — Males (2 from Darien), wing 52.9, 58.5, tail 

 49.8, 55.1, culmen from base 11.8, 11.8, tarsus 16.5, 17.2 mm. 



Female (1 from Darien), wing 49.9, tail 48.5, culmen from base 

 11.5, tarsus 17.8 mm. 



Resident. Rare ; known only from the type locality, and from 

 Cerro Mali on the Tacarcuna mountain range. 



In the original description Griscom, through a lapsus, listed the 

 type locality as "Tapalisa," but in his check-list (Bull. Mus. Comp. 

 Zool., vol. 78, April 1935, p. 353) cited it correctly as "Mt. Tacarcuna, 

 February 24, 1915." This marks the locality as the old Tacarcuna 

 village site at 575 meters elevation on the upper Rio Tacarcuna at 

 the base of Cerro Mali, a spur of Tacarcuna. 



It was known also at the time of the original description from an 

 ancient Bogota trade skin in the Paris Museum (according to Griscom 

 in the original description). Two additional specimens, a female
