JUNCO DORSALIS, Henry. 
Junco dorsalis, Henry, Pr. A. N. Sc. X, May, 1858, 117. 
Sp. Ch. —Bill black above ; light brownish below. Above, including the entire upper surface of the wings and scapulars, 
light grayish ash ; the interscapular region reddish chestnut brown. Beneath ashy white ; the middle of the belly almost pure 
white. Lores abruptly black ; quills and tail feathers nearly black. Three outer tail feathers white; two entirely so, the 
third with brown on the inner edge. Length, 6.25 ; wing, 3.05 ; tail, 3.10. 
Hah. —Fort Thorn, New Mexico. 
In tlais species the wing is rounded ; the third and fourth quills longest; the second and fifth 
very little shorter ; the first about equal to the sixth. The tail is very slightly rounded. 
The hill of this species is considerably larger than that of Junco liyemalis, and is black 
above, instead of red ; the claws, too, are larger. 
This species differs from Junco cinereus in having the chestnut of the hack restricted to the 
interscapular region, instead of having it to extend over the scapulars, wing coverts and 
outer webs of the tertials. 
The closest relationships are to J. caniceps. The plumbeous of the hack is, however, 
much lighter; the under parts generally are nearly white, instead of plumbeous anteriorly 
this color extending backwards on the sides in marked contrast with the white belly. The lores 
are much more abruptly blackish. The bill is larger ; the upper mandible black instead of 
yellowish ; the white of the tail is much the same. 
The only specimens yet known of this species are those collected at Fort Thorn by Dr. Henry.
