DESCRIPTIONS OF SOME NEW MAMMALS FROM 
WESTERN NORTH AMERICA. 
BY OUTRAM BANGS. 
THE following descriptions of apparently new species and sub- 
species of North American mammals are here published together 
as a matter of convenience. ‘The specimens described are from 
several different collections that have been purchased in the last 
few years by my brother and myself. 
Dipodomys californicus pallidulus' subsp. nov. 
Type, from Sites, Colusa Co., California, Q adult, no. 9147, coll. of E. A. and 
O. Bangs, collected June 27, 1896, by P. O. Simons. 
Subspecific characters.— Size, markings and general appearance as in true 
D. californicus. Color very much paler; thigh patches not dusky; head, back, 
sides, and especially rump, much lighter in color; the black markings at base 
of whiskers and over nose, so conspicuous in true LD. californicus, are nearly 
wanting in the new form. 
Except for its differently colored tail and smaller white spot behind the ear, 
D. californicus pallidulus about matches, in color, examples of D. merrtami 
merriam? from Arizona. 
Skull similar to that of D. californicus, except that the nasals and ascending 
arms of maxilla are shorter —not reaching so far back. ‘There is also more of 
1 Pallidulus — palish.
