Citellus tereticaudus mohavensis. 



Citellus mohavensis Merr., N. Am. Faun., No. 2, 1889, p. 15. 

 Elliot, Syn. N. Am. Mamm., 1901, p. 98. 



34 Specimens from Daggett. 



"Near the dry bed of the Mohave River, near Daggett, this 

 race was found in abundance. The burrows are usually 

 placed beneath clumps of desert willows, Chilopsis linearis, in 

 the white sand. The desert squirrel is very wary, and so pro- 

 tectively colored that it is seldom seen. The species is confined 

 to creek washes and sandy lake beds in the lower part of the 

 desert. Its note consists of a low, mellow whistle, uttered at 

 long intervals." 



In color it is practically impossible to distinguish this form 

 from C. tereticaudus, and the only differences that appear to 

 exist is that mohavensis has a shorter tail as a rule. Not deeming 

 this a sufficient character by itself to constitute a species, it seems 

 best to regard the form as only entitled to rank as a subspecies. 



Citellus chlorus. 



Citellus chlorus Elliot, Pub. Field Columb. Mus., ill, 1903, 

 p. 242. Zoology. 



8 Examples from Palm Springs. 



"Near Palm Springs this species was confined to the level, 

 sandy desert, the burrows being placed beneath thorny bushes, 

 usually mesquite. The characteristic whistling notes of this 

 group were not heard during our visit in February, which may 

 be due to their utterance during the breeding season only." 



Citellus erenomonus. 



Citellus erenomonus Elliot, Pub. Field Columb. Mus., in, 1903, 

 p. 243. Zoology. 



3 Specimens from Furnace Creek, Death Valley. 



"This is not an abundant species in Death Valley. The 

 Indians catch them for food in dead-fall traps, and their shyness 

 and scarcity is apparently due to constant persecutions of this 

 character. At the mouth of Furnace Creek the species was 

 found in mesquite thickets, but farther north in Mesquite Valley 

 no evidences of them were found."
