DIAGNOSES OF SEVEN NEW MAMMALS FROM 
EAST-CENTRAL CALIFORNIA 
BY 
JOSEPH GRINNELL anp TRACY I. STORER 
(Contribution from the Museum of Vertebrate Zoology of the University of California) 
Tn our attempts to determine the systematic status of the mammals 
encountered in our natural history survey of the Yosemite section of 
the Sierra Nevada several of the forms prove to have been heretofore 
unprovided with names. It is the purpose of the present paper briefly 
to characterize these new races, so that names will be available for 
use in our distributional studies. Incidentally, related races in other 
faunal areas have to a limited extent come in for remark. 
The color names herein employed are taken from Ridgway’s Color 
Standards and Color Nomenclature (1912). All measurements. except 
of altitude, are in millimeters. 
Scapanus latimanus campi, new subspecies 
San Joaquin Mole 
Type.—Male adult, skull and skin, in winter pelage; no. 21520, 
Mus. Vert. Zool.; Snelling, 250 feet altitude, Merced County, Cali- 
fornia; January 9, 1915; collected by Charles L. Camp; original no. 
1746. 
Diagnosis —Resembles Scapanus latimanus latimanus, but smaller, 
pelage much paler and browner, feet and claws smaller, cranium 
shorter, brain-case more inflated anteriorly, rostral region less taper- 
ing, palatal region relatively wider, and supraoccipital ridge (posterior 
to interparietal) higher. Resembles Scapanus latimanus occultus in 
color, but decidedly larger in size, especially as regards feet and claws, 
cranium heavier and much bulkier, brain-case deeper, and supra-
