Mr. Heller states that this species reaches its "western limit at 

 Trinidad, and is one of the forms that came in through the pass 

 from the desert, and the pifion zone limits its vertical range. ,r It 

 was "common on the desert a mile or more from the base of the 

 range," but at San Felipe Bay it was outnumbered by C. tereticaudus 

 and was "seen in only a few places, usually about rough canon walls."

13 Examples: 1 El Alamo, 2 Agua Escondido, San Pedro Martir 

 Mts.; 10 San Quentin, Pacific coast. 



This race would seem to be more a dweller of the lowlands than 

 of the mountains, and is not found east of the San Pedro Martir 

 range. At El Alamo Mr. Heller states that "several were seen in the 

 more sterile portions. They apparently do not hibernate anywhere 

 in their range as some were seen the latter part of November about 

 the northern part of this chain, which is probably their upper limit. 

 At San Quentin it was abundant about the creek-beds and hills."

18 Specimens. San Felipe Bay, Gulf of California. 



Mr. Heller says that this species "was very common about the bay. 

 Their burrows were usually placed in the shelter of thorny bushes. 

 They were evidently just assuming their summer pelage during the 

 first part of April as two pelages were secured among the specimens 

 taken. It has a peculiar mellow whistle. It was seen in San Matias 

 Pass on the Pacific slope, not far from Trinidad, but in that region 

 it was much less common than £. leucurus, which prefers the higher 

 parts of the desert."

All these agree with the typical style of this race, except the El
