54 nEVISION OF AMERTCAX HOLES— TRUE. 



the Klamath Lakes. Major Beiidire obtained three specimens at Fort 

 Khimath. Feilner found moles in this region in 18(54. He writes: 



I liave two kinds, one caught on Bogus Creek, with glistening silver-gray fnr, and 

 the other on Klamath River, with black fur and velvet-like appearance.' 



At the Junction of the Sierra Nevadas with the coast range at the 

 northern boundary of California the area of distribution appears to 

 divide, (»nc arm following the coast range and covering the country 

 toward the ocean, and the other extending southward in the Sierra 

 Xevadas. I liave examined one specimen from Baird, in Shasta County, 

 one from Fort Crook, and one from Berkeley, on the east side of San 

 Francisco Bay, but from the whole great Sacramento Valley specimens 

 are entirely lacking. 



Regarding tlie Sierra Nevadas we have only the testimony of Mr. W. 

 W. Price.'^ This observer obtained a specimen at Bed Point, in Placer 

 County (altitude, 4,500 feet), in the tongue of land between the north 

 aud middle forks of tlie American Eiver; but he remarks also: 



The marks of moles were seen all over the high sierras [of Placer aud Eldorado 

 counties], especially about the snow fields ou Mount Tallac, but no specimens were 

 taken. 



South of the Sierra Xevadas there are specimens from Los Angeles, 

 Alhambra, San Gal)riel, and the town and peak of San Bernardino, 

 but none from east of the mountains of this region. There are none 

 from San Diego County, but Mr. Stephens notes that the mole is com- 

 mon in damp lan<ls in the county, especially in the mountains.^ 



Thus the range of the genus is carried to the southern boundary of 

 the United States. Beyond we have only one specimen, the tyi)e of 8. 

 anthonyi from the San Pedro Martir IMountains, 150 miles south of the 

 boundary, in Lower California. The collector, Mr. Thurbcr, reported 

 that moles were rare.* 



East of the Sierras in California, as already stated, specimens have 

 been obtained in only two localities — Bijou, at the south end of Lake 

 Tahoe, and Olancha, on Owens Lake (elevation 3,700 feet).^ I think it 

 probable that the mole follows the mountains westward from the latter 

 locality along the north side of the Mohave Desert to tlie coast range, 

 and also, perhaps, northward to Lake Tahoe. A specimen recently 

 received from Tehachapi, Kern County, tends to confirm this view, so 

 far as the western extension is concerned, while Mr. Price's observa- 

 tion (already <juoted) is of interest in connection with the noithern 

 extension.
