_Penthestes gambeli baileyae_, American Ornithologists' Union
Committee (1910, p. 351), part (?).

_Type locality._--Panamint Mountains (northern part), 3 miles east of
Jackass Spring, 6200 feet altitude, Inyo County, California. _Type_,
male adult, no. 28782, Mus. Vert. Zool.; October 7, 1917; collected by
J. Grinnell, orig. no. 4588.

_Diagnosis._--The palest colored race of the four; sides, flanks and
back, in unworn plumage, pervaded with pale buff--the "cartridge buff"
of Ridgway (1912, pl. 30). Wear or fading, or both, removes most of this
buff tone, so that the resulting effect, in spring and summer birds, is
of an ashy tone of coloration, distinctly lighter than in any of the
other three subspecies, in same stage. It seems probable that there is a
paler tone to the underlying plumage parts and that this becomes
revealed by loss of the superficial pigment-bearing portions through the
gradual progress of feather abrasion. _Inyoensis_ shows nearly as long a
tail as does _gambeli_. Its bill is somewhat smaller.

_Measurements._--Average of 10 males: "Wing, 71.1 mm.; tail, 69.3;
exposed culmen, 8.1; depth of bill at base, 3.7. For extremes, see
accompanying table.

_Range._--The higher mountains of eastern California lying east and
southeast of Owens Valley, from the vicinity of the Mono Craters and the
White Mountains, in Mono County, south to the Panamint Mountains, in
Inyo County. _Specimens examined_, 50, from the following localities,
all in California:

Mono County: Mono Mills, 1; near Benton, 2; near Big Prospector Meadow,
10,000-10,500 ft.
