FAMILY TROCHILIDAE 28 1 



March 17 and April 15 (Bangs, Proc. New England Zool. Club, 1902, 

 p. 26). A male in the American Museum of Natural History was 

 collected by Benson at Chitra, Veraguas, on March 5, 1926, the only 

 record to date for this province. 



This form, found also in Costa Rica, ranges there on the Caribbean 

 slope. It is possible that in Panama it may occur also on that side 

 of the western mountains. 



DORYFERA LUDOVICIAE RECTIROSTRIS Gould 



Doryjera rectirostris Gould, Monogr. Trochilidae, Intr., vol. 1, 1861, p. 56. 

 (Nanegal, western Ecuador, designated by de Schauensee, Caldasia, vol. S, 

 no. 23, 1949, p. 535.) 



Characters. — General color paler; forehead bright metallic green; 

 crown lighter ; upper tail coverts somewhat lighter blue ; lower 

 surface paler, especially on the throat and upper foreneck. 



A male secured on Cerro Tacarcuna, Darien February 20, 1964, 

 had the iris dark brown; bare skin above and below eye light dull 

 blue ; bill black ; tarsus and toes dull brownish neutral gray ; claws 

 black. 



Measurements. — Male (one from Cerro Tacarcuna), wing 57.7, tail 

 31.4, culmen from base 37.0 mm. 



Females (3 from Cerro Tacarcuna and Cerro Pirre), wing 52.5- 

 55.7 (54.0), tail 29.1-30.6 (29.6), culmen from base 35.6-37.9 (36.5) 

 mm. 



Resident. Apparently rare in the Subtropical Zone of the mountains 

 of Darien. 



E. A. Goldman secured 2 females April 20 and 30, 1912, at 1,580 

 meters near the head of Rio Limon on Cerro Pirre. On Cerro 

 Tacarcuna, C. O. Handley, Jr., collected male and female caught 

 February 20 and 28, 1964, in mist nets at 1,250 and 1,340 meters. 

 These agree in length of bill with birds from western Ecuador, but 

 have the wing slightly shorter. 



Specimens of this race from western Colombia and western 

 Ecuador have the following measurements : Males (9 from Cauca 

 and the western slope of Pichincha) wing 61.0-64.5 (62.3), tail 

 31.5-34.7 (32.9), culmen from base 35.2-38.3 (36.5) mm. 



Females (4 from western Colombia and western Ecuador), wing 

 60.1-62.6 (61.6), tail 31.0-32.8 (32.1), culmen from base 35.2-37.5 

 (36.3) mm. 



The race rectirostris, which ranges through the western Andes of 

 Colombia to western Ecuador, is similar in color to D. I. ludoviciae
