List of specimens. 



JUNCO CANICEPS, Baird. 



Struthus cankeps, Woodhouse, Pr. A. N. So. Phila. VI, Dec. 1852, 202. (New Mexico and Texas.) — Ib. Sitgreave's 

 Report Zuixi & Colorado, 1853, 83 ; pi. iii. 



Sp. Ch. — Bill yellowish ; black at the tip. Above dark plumbeous, the head and neck all round of this color, which extends 

 (paling a little) along the sides, leaving the middle of the belly and crissum quite abruptly white. Lores conspicuously, but 

 not very abruptly darker. Interscapular region abruptly reddish chestnut brown, which does not extend on the wings, except 

 perhaps a faint tinge on some of the greater coverts. Two outer tail feathers entirely white ; third with a long white terminal 

 stripe on the inner web. Length, 6.00 ; wing, 3.23 ; tail, 3.04. 



Hob. — Rocky mountains ; from Black Hills to San Francisco mountains. New Mexico. 



This species is very similar to the common J. hyemalis in color, except that the plumheous of 

 the under parts and sides is not quite so dark and less abruptly defined against the white. The 

 conspicuous chestnut patch on the back will distinguish them. The outer web of the third tail 

 feather is brown, not white. It differs from oregonus and cinereus in having no chesnut on the 

 wings, especially the tertials, and from the former in the extension of the ash of the neck along 

 the sides. It is darker above than J. dor sails, which also lacks the distinct plumbeous of the 

 throat and sides, has the bill blacker, the lores more abruptly darker, &c.
