MAMMALS OF UTAH 37 



ing the black, or at most it is but faintly indicated; outer 

 pair of dark stripes nearly obsolete, just a shade darker 

 than the color of the flanks ; inner pair of light stripes not 

 very distinct, grayish white; outer pair much whiter and 

 clearer; rump and flanks grayish; sides of body and upper 

 surfaces of feet light briglit rufous ; a distinct, large white 

 postauricular spot afld posterior half of ear whitish; light 

 facial stripes quite white; dark ones rufous, the lower run- 

 ning distinctly around under ear ; top of head mixed gray- 

 ish and rusty, with some black hairs intermixed; below, 

 grayish white ; tail above, mixed black and chestnut ; below 

 bright chestnut with indistinct black border. Total length, 

 8.5; tail vert. 3.5; hind foot 1.25. (Warren.) 



Distribution — Northern Arizona, southeastern Utah, 

 southwestern Colorado and northwestern New Mexico. Sev- 

 eral specimens have been taken at Dragon and Bluff City, 

 Utah. 



Habits — In size and general appearance the Hopi chip- 

 munk resembles E. quadrivittatus of the eastern foothills, 

 but its movements are more deliberate and its colors much 

 brighter and richer. The long tail is carried more nearly 

 horizontally even when the animal is running. This strik- 

 ing habit, together with the graceful downward curve of the 

 tail near the tip, serves to distinguish it, even at a distance, 

 from the small E. consobrinus, with which it commingles 

 in the higher parts of its range. In the juniper country 

 south of White river its habits of leaping up a tree when 

 alarmed and hiding on the opposite side of a branch may 

 cause it to be confused with the gray utahensis, which is 

 found in similar country in the Escalante Hills. The Hopi 

 chipmunks appear equally at home among the hot rocks in 

 the precipitous canyons and in the dense junipers and pinon 

 growth which clothes the bordering mesas. They feed ex- 

 tensively upon .the berries of Juniperus monosperma 

 throughout their range. (Cary.)
