Syjionyms. — No other names have been based upon indi- 

 viduals of this race. Specimens have been referred sometimes 

 to hammondii, sometimes to vagrans, or elegans. 



Range. — This subspecies is the common water-snake of the 

 Sacramento and San Joaquin valleys of California from Shasta 

 to Kern counties. It ranges west into Monterey County, where 

 it has been taken in the valleys of the Carmel River and San 

 Antonio and Nacimiento creeks. It ascends the valley of the 

 Kern River to an altitude of some 6000 feet, and, doubtless, 

 crosses through Walker Pass to the east side of the Sierra 

 Nevada where it occurs in Owens Valley and about Pyramid 

 Lake and Lake Tahoe. Its range lies chiefly in the Lower and 

 Upper Sonoran zones.
