occipital ridge higher. Differs from Scapanus latimanus sericatus in 
much paler and browner color, claws shorter and blunter, cranium 
larger and broader, mastoid and interorbital breadths greater, and 
brain-case more inflated. 
Material—Three specimens from Snelling, Merced County, Cali- 
fornia (nos. 22004, 22005, 21250, Mus. Vert. Zool.) ; one specimen 
(injured skull and skeleton) from three miles north of Sanger, Fresno 
County, California (no. 18854, Mus. Vert. Zool.). Both these localities 
he in the Lower Sonoran Zone.

Remarks.—The imperfect specimen from Sanger, by Jackson (1915, 
p. 69) referred provisionally to occultus, seems to us to be better placed 
with the form here newly characterized. It seems likely that campi 
will be found to inhabit river-bottom lands of the San Joaquin Valley 
generally, at least on the east side. 
The form is named for Mr. Charles Lewis Camp, in recognition of 
his ability as a field naturalist. 
Martes caurina sierrae, new subspecies 
Sierra Pine Marten 
Type.—Male adult, skull and skin, in summer pelage; no. 22112, 
Mus. Vert. Zool.; head of Lyell Canon, 9800 feet altitude, Yosemite 
National Park, California; July 24, 1915; collected by Charles D. 
Holliger; original no. 562. 
Diagnosis.—Siunilar to Martes caurina caurina, but general colora- 
tion paler both above and below, this paleness involving both overhair 
and fur; sides of face decidedly paler; pale ochraceous-orange of chest 
very extensive, spreading forward to throat and backward along 
median line to belly; ‘‘feel’’ of pelage softer; cranium with rostrum 
short as in caurina, but extremely narrow; whole cranium narrower, 
and brain-case relatively higher; sagittal crest very weak; auditory 
bullae even smaller than in cawrina. 
Material—Nine skins with skulls, some also with body skeletons, 
from various points in the Hudsonian Zone of the Yosemite National 
Park, Mariposa and Tuolumne counties, California.
