 antly at frequent intervals or even on rarer occasions rose in the air 

 for a flight song. 



BRACHYSPIZA CAPENSIS CANICAPILLA (Gould) 



Zonotrichia canicapilla Gould, Zool. Voy. Beagle, pt. 3, Birds, 1841, p. 91. 

 (Port Desire, Patagonia, and Tierra del Fuego.) 



The present form of Brachyspiza was the breeding species at 

 Zapala, Neuquen, though at General Roca, a few meters lower, 

 I found the more familiar type with a black streak on either side of 

 the crown. B. c. canicapiUa was fairly common through the brush 

 that grew in scattered clumps over the gravelly hills above the town 

 of Zapala on December 7, 8, and 9, and one specimen was taken on 

 each of the two dates last mentioned. On December 7 a female 

 flushed from a nest placed in a depression in the sand under a little 

 bush and ran rapidly away with lifted wings. The nest was a cup 

 of grasses and weed stems, lined warmly with small rhea feathers. 

 The two heavily incubated eggs have a ground color paler than pale 

 Niagara green, finely dotted with Rood's brown, the dots more or 

 less confluent in small irregular blotches, heavier about the larger 

 end, where they are accompanied by minute, scattered spots of black. 

 The markings in one egg are soft and suffused, in the other bolder 

 and more restricted. These eggs measure, respectively, 18.5 by 14.4, 

 and 18 by 14.5 mm. 



At Potrerillos, Mendoza, on March 20, 1921, I killed an immature 

 female of the present race, in company with B. c. cMlensis. I sup- 

 posed that it was a migrant from some more southern region. These 

 records probably mark near the northwestern extension of the range 

 of canicapilla^ both during the breeding season and in migration. 



BRACHYSPIZA CAPENSIS CHILENSIS (Meyen) 



Fringilla chilensis Meyen, Nov. Act. Acad. Caes. Leop.-Carol. Nat. Ciu-ios., 

 vol. 16, Suppl., 1834, p. 88. (Santiago, Chile."") 



At Concon, Chile, this form was common from April 24 to 28, 1921, 

 and five specimens were taken on April 24, 25, 26, and 27. These 

 include adult and immature birds all in full fall plumage. Five 

 additional specimens secured at Potrerillos, Mendoza, in the Andean 

 foothills, while not wholly typical, are so near chilensis from Chile 

 as to forbid their separation. The bird was common in this vicinity, 

 in brushy areas near streams, in the valleys, and along the canyon 

 walls from March 15 to 21, 1921. Two adult males (taken March 19 

 and 20) have not quite completed the post-breeding molt. An adult
