Type locality. — Fort Bridger, Uinta Co., Wyoming (C. Drexler). 
Measurements. — Total length, 10.8 ; tail vert., 3.0; hind foot, 1.75. 
Description. — (From a specimen taken in Coyote Basin, Routt 
Co., July 2d): Upper parts brown, with an indistinct mottled or 
spotted appearance caused by the tips of the hairs being black; 
in some lights the animal seems to be transversely crossed by narrow 
irregular wavy black lines; top of head like back but without the 
spotted appearance ; sides, flanks, and upper surface of feet pale 
fulvous ; underparts (except chin) a somewhat paler shade of fulvous ; 
chin whitish; light whitish-buff ring around eye; tail above mixed 
brown and black, tip black edged with whitish; below brown or 
fulvous, about like sides, with black tip. Specimens in spring, in 
worn pelage, are somewhat grayer and paler. 
Distribution. — This species is found in Wyoming, Colorado, and 
Utah. In Colorado it has been found in Larimer, Grand, Routt, 
Rio Blanco, Eagle, and Summit counties, at elevations from a little 
below 6,000 up to 9,000 feet. Fish Creek, Larimer County, near 
the Wyoming line, is the most northeasterly Colorado record; I 
found it in Routt County to about ten miles west of Lay; Minturn, 
Eagle County, and Dickey, Summit County, are the most southern 
records. 
Habits. — The Picket-pin Gopher is a burrowing animal, 
living in colonies like prairie dogs, though not throwing up 
large mounds like the latter, nor, being a smaller animal, do
