The specimen mentioned, collected in summer 1864, was destroyed 

 with the Academy collections in the Chicago fire of 1871. 



CONTOPUS SORDIDULUS PENINSULAE Brewster 



Contopus richardsonii pcninsulae Brewster, Auk, vol. 8, no. 2, April (February 

 17), 1891. p. 144. (Sierra de la Laguna, Baja California, Mexico.) 



Characters. — Definitely paler gray above and below ; bill longer 

 and broader. 



Measurements. — Males (10 from Baja California), wing 79.3-85.2 

 (82.8), tail 54.2-61.0 (57.7), culmen from base 17.0-18.8 (17.7, 

 average of 9), tarsus 12.2-12.7 (12.5 ) mm. 



Females (5 from Baja California), wing 77.3-81.2 (79.3), tail 

 55.7-58.8 (57.3), culmen from base 16.7-18.1 (17.3), tarsus 12.4- 

 12.8 (12.6) mm. 



Migrant from the north, in part passing to South America ; 

 abundance uncertain. 



The few records include one of doubtful sex collected October 26, 

 1931, at Quiel, above Boquete, by R. R. Benson, and a female, with 

 the body plumage partly in molt, taken February 15, 1966, on the 

 headwaters of the Rio Corotu, at the edge of the forest west of 

 Puerto Armuelles, Chiriqui. The second specimen is small and, in 

 general, pale in color, with bill especially broad, in which the culmen 

 measures 17.3 mm. Another female in the American Museum of 

 Natural History, shown to me by Eisenmann, was collected by E. S. 

 Morton on Cerro Campana, Panama, August 13, 1970. It was identi- 

 fied as the present race by Allan Phillips. 



This race has its breeding ground in southern Baja California. In 

 size and coloration it is closely similar to griscomi, differing in the 

 larger, broader bill. As it is little known in its migrations, it is inter- 

 esting to record a male taken by M. A. Carriker, Jr., September 4, 

 1946, at Buenos Aires, in central Norte de Santander, Colombia, now 

 in the National Museum.

Characters. — Paler ; lighter gray on the dorsal surface, lighter 

 below, in this resembling C. s. peninsiilae but with bill shorter and 

 narrower. 



Measurements. — Males (2 from the type locality), wing 81.7, 85.0;
