_Type locality._--Mount Wilson, 5500 feet altitude, San Gabriel
Mountains, Los Angeles County, California. Type in coll. J. Grinnell.

_Diagnosis._--Tone of coloration on sides, flanks and back distinctly
plumbeous--more exactly, on sides and flanks the "smoke gray" of Ridgway
(1912, pl. 46), and on back near the "mouse gray" of the same authority
(pl. 51). The tail in this race is short as in _abbrevialus_, but the
bill is long and heavy, averaging thicker through than in any of the
other three races.

_Measurements._--Average of 14 males: Wing, 70.0 mm.; tail, 65.4;
exposed culmen, 8.5; depth of bill at base, 4.1. For extremes, see
accompanying table.

_Range._--Higher mountains of southern California, from the extreme
southern Sierra Nevada in Tulare County, and the Santa Lucia Mountains
in Monterey County, south to the Cuyamaca Mountains, San Diego County;
also (probably this subspecies) in the San Pedro Martir Mountains, in
northern Lower California. _Specimens examined_, 160, from the following
