132 The Mammals of Colorado 
Wyoming, Colorado, western Oklahoma, and northwest Texas. Its 
range in Colorado might very well be described as that part of the 
State not occupied by the preceding species. It has been taken 
at Yarmany Creek, Eagle County; Yampa, Steamboat Springs, 
Craig, Lay, Sand Creek, Lily, Snake River, Douglas Spring, Escal- 
ante Hills, and Ladore, Routt County; Buford, Meeker, White 
River, and Rangely, Rio Blanco County; Baxter Pass, Garfield 
County; Grand Junction and Fruita, Mesa County; Fort Collins and 
Loveland, Larimer County; Valmont, Boulder County; Barr, Adams 
County; Littleton, Arapahoe County; Wray, Yuma County; 
Flagler, Kit Carson County; Eastonville, and Colorado Springs 
and vicinity, up to at least 11,500 feet. El Paso County; Divide, 
Teller County; Gaume's Ranch, northwest corner of Baca County; 
Irwin's Ranch, northeast Las Animas County. Many specimens 
from points where the ranges of this and the preceding form ap- 
proach are really intermediate, and in such cases it is necessary 
to make rather arbitrary decisions as to where to place them. 
Habits. — The habits have been sufficiently described under 
the preceding species. 
Peromyscus maniculatus luteus (Lat., yellow). Yellow 
Deer-Mouse. 
Peromyscus luteus Osgood, Proc. Biol. Soc. Wash., xviii., p. 77 
(1905)- 
Type locality. — Kennedy, Cherry Co., Neb. 
Measurements. — Total length, 6.0; tail vert., 2.6; hind foot, 0.78. 
Description. — (From a specimen taken at Kennedy, Neb., Apr. 23d, 
Biological Survey No. 18657): Above, rather a bright pale tawny 
color, darkest on dorsal region, rather whitish around and below 
ears. Upper portion of tail somewhat darker than the back. 
Feet and entire underparts white. Easily distinguished in typical 
form, from either of preceding, though nebrascensis is the only 
one whose range it adjoins. 
Distribution. — The Yellow Deer-mouse is, at present, known only 
from Nebraska, Kansas, South Dakota, Wyoming, and Colorado, 
and possibly extending into Oklahoma and North Dakota. In 
Colorado the only positive record is Fort Collins, though specimens 
from Wray, Yuma County, have been pronounced by W. H. 
Osgood as very close to luteus, which has been taken at Haigler, 
Nebraska, about eight miles east of the Colorado line, while Wray 
is the same distance west. Much more information is needed about 
the distribution of this species.
