DECEMBER, 1903. MAMMALS ELLIOT. 243 



Citellus *eremonomus. Sp. nov. 



Type locality: Furnace Creek, Death Valley, Inyo County, Cali- 

 fornia. 



Genl. char.: Size small; color a darker vinaceous than that of any 

 other member of the unspotted group of Citellus; tail with only basal 

 half like that of the upper parts. Skull similar to that of C. moha- 

 vensis, but processes of the pterygoids do not touch the bu-llae. 



Color: Upper parts grizzled vinaceous cinnamon; sides of face, 

 nose, and body, inner sides of legs, and entire under parts, silvery 

 white; fore feet pale brown, hind feet whitish; tail above, basal half 

 grizzled vinaceous cinnamon like the back, terminal half blackish 

 mixed with white hairs, and narrowly edged with white, under part 

 silvery white at base, remainder buff mixed with black, bordered and 

 tipped with black, and narrowly fringed with white. Ears very small, 

 similar in color to the back. 



Measurements: Total length, 252; tail vertebrae, 89; hind foot, 

 35; ear, 8.5. Skull: total length, 36; occipito-nasal length, 35; 

 Hensel, 30; zygomatic width, 23; interorbital constriction, 9.5; 

 palatal length, 17; length of nasals, 12; length of upper tooth row, 7; 

 length of mandible, angle to tips of incisors, 25 ; length of lower tooth 

 row, 7. 



This form in its coloring is quite different from any of those 

 described belonging to this particular group, and its peculiar vina- 

 ceous cinnamon color with the plumbeous bases of the hairs showing 

 through at intervals gives it a somewhat scaly, harsh appearance, more 

 like the members of the harrisi group, but without any stripe. It was 

 not common in the locality in which it was taken, for Mr. Heller, who 

 collected the specimens, was able to secure only three individuals.
