SCr HID^— SPERMOPHILDS GRAMMURUS AND VARIETIES. 833 



Geographical distribution. — The habitat, of Spertiiophilus grammurus 

 van grammurus extends from the parks of Central Colorado soutliward into 

 Mexico, probably to a considerable distance beyond the boundary of the United 

 States. In some portions of Colorado, as in the vicinity of Boulder, whence 

 many specimens have been brought, it appears to be a common and character- 

 istic species. It occurs in Western Texas, but further north does not appear 

 to occur much to the eastward of the eastern base of the Rocky Mountains. 

 It ranges thence westward to, and probably throughout, the Great Basin, at all 

 favorable localities. There are specimens in the collection frOm Ogden and 

 Prove, Utah, and Virginia City, Nev. Var. douglassi ranges from Nortliern 

 California to Fort Dalles and Klamath Lake, Oreg. In Northern California, 

 it gradually passes into var. beecheyi, which ranges thence southward through- 

 out Southern California, and probably further southward. The most southern 

 points represented in the collection arc Fort Tejon and San Diego. Speci- 

 mens referable t j beecheyi have been collected by Mr. H. W. Henshaw on the 

 eastern slope of the Sierra Nevadas. The species grammurus hence ranges 

 from the eastern base of the Rocky Mountains to the Pacific coast, and from 

 beyond the Mexican boundary northward to Central Colorado, Northern Utah, 

 and Oregon.*

" This species is apparently more or less active at soutbern localities (brongbout tbo wiuter. 

 Mr. T. O. Gary, wbo formerly resided many years in California, and knows (be spccivs well, assures mo 

 that about San Mateo tbey were to be net with abuudantly at all seasons, apparently spending no por- 

 tion of the year in a state of hlbernaticr<. This is confirmed by the observations of Dr. Coues, wbo 

 enjoyed ezcellont opportunities of stadying its uubits in Soutbern Californiu, and wbo found it as active 

 as ever during the latter part of November, 1865, in the vicinity of San Pedro. Dr. J. O. Cooper also 

 states that on the Los Angeles Plains, in the southern part of the State, they " dn not hibernato ", 

 but may bo sen.i there in winter actively ranning about or littlng erect near their barrows.— (.imerioan
