Remarks.—The Yosemite series of specimens, as regards both skins 
and skulls, is notably uniform in characters, and is doubtless repre- 
sentative of the race occupying the Boreal Zone along the whole Sierra 
Nevada, north at least to Mount Shasta. The specimens referred to 
caurina with some reservation by Miss Kellogg (1916, p. 356) should 
now be referred to sierrae. They are not typical of that race, however, 
showing departure in cranial characters towards cawrina proper. 
Eutamias amoenus monoensis, new subspecies 
Mono Chipmunk 
Type.—Male adult, skin and skull, no. 23380, Mus. Vert. Zool.: 
Warren Fork of Leevining Creek, 9200 feet altitude, Mono County, 
California; September 25, 1915; collected by J. Grinnell; original no. 
3709. 
Diagnosis —Similar to topotypes of Hutamias amoenus amoenus, 
in corresponding pelage (post-breeding), but general tone of coloration 
paler, more grayish; top of head, central pair of light stripes on back. 
and rump, with proportion of white to red greater; ochraceous-tawny 
of sides paler; tips of dorsal tail hairs light buff rather than yellow- 
ochre; light middle portion of ventral surface of tail ochraceous-buft 
rather than ochraceous-tawny. 
Material.—All from California: Twenty-one specimens from Mono 
County: Walker Lake, 8000 feet; Silver Lake, 7200 feet; Gem Lake, 
9036 feet; Mono Craters, 7500-8000 feet; Williams Butte, 7000 feet: 
and Warren Fork of Leevining Creek, 9200-9400 feet; twenty-three 
specimens from Placer County: Cisco, 6000 feet; Soda Springs, 6500 
feet; twenty-six specimens from Nevada County: Independence Lake,
