1 Length, 4.25; extent, 5.75. Iris brown; bill black; feet lead color. 
PSALTRIPARUS PLUMBEUS, Baird. 
Psaltria plumbea, Barry, Pr. A. N. Se. Phil. VII, June 1854, 118. Little Colorado. 
Sp. Cu.—Tail long, feathers graduated. Above rather light olivaceous cinereous. Top of head rather clearer ; forehead, 
chin, and sides of head, pale smoky brown, Beneath brownish white, scarcely darker on the sides. Length, about 4.20 inches ; 
wing, 2.15; tail, 2.50. 
Hab.—Southern Rocky mountains. 
This diminutive species has the bill slender, the point of the upper mandible elongatee and 
gently curved. The tail is long, slightly emarginate, but graduated on the sides; the exterior 
abruptly shorter than the rest, which are rounded more regularly. The greatest difference 
between the longest and shortest feathers is .45 of an inch. The fifth quill is longest, the 
sixth and fourth barely and successively shorter ; the third and eighth about equal ; the second 
shorter than the secondaries. The entire upper parts are of a bluish ash with an olivaceous 
shade, rather clearest on the head. The sides of the head and the chin are pale smoky brown; 
the forehead is tinged with the same. The under parts are dirty brownish white, lightest on 
the throat, a little more brown on the sides of the body. The tail feathers and quills are edged 
externally with the color of the back; the edges of the third and seventh primaries slightly 
paler. 
Specimens vary somewhat in the clearness of their tints, which are sometimes a little darker, 
sometimes lighter. 
This species is very similar to the Psaltriparus minimus of the west coast, which it represents 
in the Rocky mountain region. It is, however, appreciably larger, the wings and tail propor- 
tionally longer. The top of the head is plumbeous, uniform with the back, instead of smoky 
brown. ‘The back is a paler ash, the under parts darker. 
The specimens ccllected by Messrs. Kennerly and Mollhausen are labelled differently as 
respects the color of the iris, some being marked as yellow, others as black. I find no other 
appreciable difference, however, between them.
