66 BANGS — NEW AMERICAN MAMMALS a ee 
a depression in the frontals just behind the nasals, that part of the skull being 
less evenly rounded. 
Color.— Upper parts wood brown, shading toward cinnamon on lower sides, 
and slightly darker on top of head and along back; small patch behind ear 
and spot over eye white; thigh patches wood brown, shaded with cinnamon; 
a very small and inconspicuous dusky spot at base of whiskers; space between 
whiskers and eye yellowish white; tail as in true D. californicus. 
Measurements.—Type, Q adult: total length, 290; tail vertebra, 181; hind 
foot, 42; ear,15 mm. Topotype, no. 9148, 9 , young adult, total length, 273; 
tail vertebrae, 160; hind foot, 44; ear, 12 mm. 
Remarks.—The two specimens upon which I have based the 
new subspecies were caught at the same place on the same day. 
They are very similar, the younger example being, if anything, 
paler than the type. 
Dipodomys californicus pallidulus differs much from true D. 
californicus, of the coast, in its pale colors — DV. californicus being, 
as Dr. Merriam said in his original description of it, one of the 
darkest members of the genus. 
Neotoma bella’ sp. nov. 
Type from Palm Springs, Riverside Co., California, J, old adult, no. 5308, 
coll. of E. A. and O. Bangs, collected April 12, 1896, by E. C. Thurber. 
General characters.— Belonging to the zxtermedia-lepida® group. Size larger 
than J. /epida and smaller than J. zz/ermedia gilva. Color very much paler 
than in either; tail well haired, very light in color, and scarcely darker above 
than below. Skull differing from that of 1. zztermedia gilva in being smaller, 
with shorter, heavier rostrum and wider nasals, audital bulle larger, inter- 
parietal narrower. From J. /efzda it differs in having rather narrower brain- 
case, heavier rostrum, shorter nasals with maxillary arms extending farther 
backward behind them, audital bulle larger. 
Color.— Upper parts pale buff-yellow, somewhat lined along back with 
brownish-black-tipped hairs; a white patch at base of ear; cheeks, sides and 
upper surfaces of legs and arms pale orange-buff; head pale grayish buff- 
yellow; whiskers mixed black and white; under parts pure white —no pec- 
toral collar —the hairs white to the base, except along lower sides and on 
under surface of legs, where they are pale gray at base; white of under parts 
1 Bellus — pretty. 
2 Mr. Gerrit S. Miller, Jr., after examining the type, in the British Museum, of Meotoma 
lepida Thomas, is of the opinion that it is the same as WV. desertorum Merriam.
