This species comes nearest to Leucosticte griseinucha of Brandt, 

 1842 ; L. griseigenySj Gould, an inhabitant of Russian America 

 and the Aleutian Islands. This latter species may, however, be at 

 once distinguished by the possession of gray cheeks and ear 

 coverts. 



10. Otocoris occidentalis, McCall. 



Otocoris occidentalis, McCall, Pr. A. N. S. Phil. V. 118 (June, 1850). 



This species of sky lark is founded by Colonel McCall upon 

 an immature bird, shot near Santa F^ in July. Captain Stans- 

 bury's specimen was killed near Salt Lake City, March 18, 1850, 

 and is, consequently, an adult, in winter plumage. It differs from 

 winter specimens of Otocoris alpestris, in having no yellow on the 

 throat and superciliary stripe, more black on the cheeks, and 

 less on the breast, and a very slight ferruginous tinge of the upper 

 parts and sides of the body. The white across the forehead is 

 more distinct. The bill is shorter, more slender, and more curved.
