25. CHARINA 641 
Distribution.—The Rubber Snake, or Two-headed Snake 
as it is often called because of its blunt tail, is not rare in the 
moister portions of California, Oregon, Washington, and 
western Nevada. It usually is found in or near coniferous 
woods. 
In California, it seems to be restricted to the coast region 
and the Sierra Nevada and has not been found south of 
Tulare County. It has been taken in Siskiyou (near Mount 
Shasta), Lassen (south base of Mount Lassen, Eagle Lake), 
Nevada (Donner Lake), Placer (Red Point, Summit Soda 
Springs, Cisco, Tahoe City), El Dorado (Strawberry Valley, 
Fyffe, Mount Tallac, Fallen Leaf Lake), Calaveras (Moke- 
lumne Hill), Mariposa (Yosemite Valley), Fresno (Fresno, 
Huntington Lake), Tulare (Redwood Canyon East Fork 
Kaweah River), Humboldt (Humboldt Bay), Trinity (Cof- 
fee Creek), Mendocino (Comptche), Sonoma (Russian 
River near Rio Campo), Marin (Point Reyes, three miles 
west from Inverness, Sausalito, Mt. Tamalpais), Alameda 
(Berkeley, Temescal, Oakland), San Francisco (Presidio), 
San Mateo (Halfmoon Bay), Santa Clara (Palo Alto, 
Black Mountain), Santa Cruz (Big Basin, Santa Cruz, So- 
quel), and Monterey (Carmel), counties. 
In Nevada, it has been secured on the Humboldt River, 
at the big Bend of the Truckee River, and in Ormsby 
County and at Glenbrook, Douglas County. 
In Oregon, it has been taken in Lake (Summer Lake), 
Douglas (Drain), Lane (Blue River, McKenzie Bridge), 
Marion (Salem), and Clackamas (Milwaukee), counties, 
and in the Upper Willamette Valley between Portland and 
Salem, the John Day Valley, and at Bourne. Specimens 
have also been collected in Baker County, and near Wallowa 
Lake, Wallowa County, but I do not know whether they 
are of this subspecies or C. bott@ utahensis. 
In Washington, it has been secured in King (Seattle),
