September 24 (= Sept. 27), 1912, p. 4. (Marraganti, Darien, Panama.) 



Characters. — Distinctly darker on lower surface, with the throat, 

 lower breast, and abdomen dull brown, rather than green ; somewhat 

 smaller. 



A female taken near Chiman, Panama, February 23, 1950, had 

 the iris dull reddish brown around the pupil, changing to brownish 

 yellow at the outer margin ; bill black ; upper half of tarsus dull 

 brown, with the scutes edged with dark neutral gray, changing lower 

 down, and over the toes, to dark neutral gray throughout. 



Measurements. — Males (10 from Canal Zone, eastern Province 

 of Panama, and Darien), wing 123.5-133.1 (129.0), tail 220-258 

 (238.0), oilmen from base 39.6-45.5 (42.7), tarsus 29.1-32.8 (30.1) 

 mm. 



Females (10 from Canal Zone, eastern Province of Panama, and 

 Darien), wing 119.3-128.9 (125.9), tail 216-241 (236.0), culmen 

 from base 38.6-43.1 (41.5), tarsus 28.6-30.5 (29.2) mm. 



Resident. Common throughout the lowlands where there is forest 

 cover; recorded on the Pacific slope from Capira, western Province 

 of Panama, eastward through Darien ; on the Caribbean side in the 

 Canal Zone and the lower Chagres Valley inland to Madden Dam ; 

 also recorded in eastern San Bias at Perme and Puerto Obaldia. 



In the Canal Zone this race is found in the lower valley of the Rio 

 Chagres from above Juan Mina near Madden Dam, to below Gatun. 

 In the western sector of the Province of Panama 1 was collected by 

 Carl Bovallius near the mouth of the Rio Caimito on June 3, 1882, 

 presumably near Puerto de Chorrera on the coast, as he traveled by 

 schooner. There is also a specimen in the U.S. National Museum, 

 labeled Chorrera, taken "early in 1914," presented by James Zetek, 

 in which the locality is considered authentic. The most western 

 record is a male in the Carnegie Museum, collected at Capira, April 13, 

 1939, by Arthur C. Twomey. In Darien I found them common in 

 the valley of the Rio Tuira and the Rio Chucunaque. They are 

 recorded also at Garachine, and in the lower valley of the Rio Sambu. 

 At the mouth of the Rio Imamado, in the upper Rio Jaque drainage, 

 I heard one or two calling regularly from hills near our camp, but 

 did not succeed in locating them. From the far eastern San Bias, 

 H. von Wedel forwarded 3 from Perme to Griscom (Bull. Mus.
