there it was mid-winter, and they were frequenting the wooded 

 ravines in the Sierras ; towards spring they commenced to visit the 

 valley early in the morning, but as the weather became warmer 

 seemed to abandon the mountains altogether. I obtained my speci- 

 mens as they came to feed on some bees that were kept not far from 

 our encampment. 



The male is of a beautiful scarlet, the female yellow ; and evidently 

 the first plumage of the young male is also yellow, but subsequently 

 gradually changes with the growth. Of this I was rendered certain 

 by the capture of several specimens undergoing the process of trans- 

 formation. 



4. DONACOSPIZA ALBIFRONS (Vicill). 



d . Cosquin, Cordova, Arg. Rep., July 5, 1882. 



Iris sepia. 



This is the only specimen I have seen of this bird, and one I ob- 

 tained only by accident, as when I shot it I thought it to be a common 

 Zonotrichia. It was met with in the well-wooded lands that fringe 

 the mountain-slopes.

5. GUBERNATRIX CRISTATELLA (VieiU.). 



S. Cosquin, Cordova, Arg. Rep., Sept. 11, 1882. 



Iris very- dark. 



I noticed these birds for the first time at Cosquin on the 22nd of 

 July, after a snowstorm ; three were together in the well-wooded 

 lands up near the mountains. In the valley below, however, and in 

 August they are met with more abundantly, but by no means com- 

 monly, and then always fly in pairs. 



6. Zonotrichia strigiceps (Gould). 



cJ . Cosquin, Cordova, Arg. Rep., June 16, 1882. 

 $_. „ „ ,, Aug. 15, 1882. 



Iris dark brown. 



At first sight I mistook this bird for the Chingolo (Z.pileafa) ; but 

 the moment its chirp met my ear (a peculiar metallic ring) I knew it 

 to be of a different species. It was met with, in a flock of about 

 fifteen, in a well-wooded ravine at a tolerable elevation up the 

 mountains, and only at one spot. 



7. Tjenioptera dominicana (VieilL). 



cf. La Plata, Buenos Aires, Arg. Rep., Nov. 21, 1882, 

 Iris dark brown. 

 Rather rare here.
