FAMILY TYRANNIDAE 505 



and toes pale neutral gray ; claws brownish white. A male, collected 

 on the same day, was similar. 



Measurements. — Males (10 from Chiriqui and Darien), wing 58.2- 

 62.3 (60.1), tail 27.6-32.8 (31.3), culmen from base 12.5-13.9 

 (13.2), tarsus 17.0-18.5 (17.9) mm. 



Females (10 from Bocas del Toro, Chiriqui, and Darien), wing 

 52.3-58.9 (54.5), tail 20.7-30.8 (27.2), culmen from base 12.4-13.8 

 (13.0), tarsus 15.4-16.9 (16.1) mm. 



Resident. Locally fairly common in forested areas in the upper 

 Tropical and lower Subtropical Zones. Chiriqui : Cerro Punta, El 

 Volcan, Barriles, Boquete. Lerida, Quiel, Cerro Flores. Bocas del 

 Toro : in the higher elevations on the Holcomb Trail, beyond Boquete 

 (with one record from the lowlands near Almirante). Veraguas: 

 Calovevora, Santa Fe, Chitra, Calobre, Cerro Montuosa, northwestern 

 Azuero Peninsula. Province of Panama : Cerro Compana. Darien : 

 Garachine, Cerro Pirre (Cana), old Tacarcuna village site, Cerro 

 Nail, Cerro Tacarcuna (1250 meters). La Laguna (900 meters). 



Specimens in the Salvin-Godman collection in the British Museum 

 were taken in Veraguas by Arce at Calovevora on the Caribbean 

 slope, and Calobre on the Pacific side. Salvin (Proc. Zool. Soc. Lon- 

 don, 1870, p. 196) in an early account of Arce's collections, listed it 

 also from Chitra, where it was taken later by Benson. 



This species, rather closely similar to Platyrinchus coronatus, is 

 readily identified by its white throat and olive (olive and yellow in 

 the male) crown, with no trace of cinnamon-brown. In the hand it 

 appears slightly heavier in body, but otherwise is similar in form. 



Like its companion, found mainly at lower elevations, it ranges in 

 the undergrowth in heavy forest alone or in pairs. A male, captured 

 in a mist net, in my hand expanded the yellow area in the crown 

 laterally and vertically so that it made a handsome show. I noted 

 them moving rather quickly through the undergrowth when feeding, 

 uttering a sharp, chipping call. 



A single bird, a female, taken January 22, 1958, at sea level in a 

 dark, wet thicket in Water Valley near the bay at Almirante, Bocas 

 del Toro, is the only record for this locality. I found these birds 

 elsewhere only above 900 meters elevation in mountain areas, both 

 in Chiriqui and in Darien. 



Dr. Alexander Skutch (in litteris, 10/15/70), has sent me the 

 following description of a nest found April 21, 1938, near Vara 

 Blanca, Costa Rica, at 1700 meters. The "neat, compact structure, 

 shaped like an inverted cone, rested in a V-shaped, upright crotch in a
