Distribution. The original specimens of this snake were 

 collected in northern Lower California by William M. 

 Gabb. I have examined a specimen taken at Ensenada, 

 Lower California, on June 8, 1 893. Thence the species 

 ranges north through southern California and east to western 

 Arizona. A dried specimen found by Mr. Slevin on Mejia 

 Island, in the Gulf of California, seems to belong to this 

 species. 



In Arizona, it has been secured only in the Harqua Halla 

 Mountains in northwestern Maricopa County, but has been 

 seen also in the Harcuver Range in northeastern Yuma 

 County. 



In California, it has been collected in the Providence 

 Mountains in the northeastern part of San Bernardino 

 County, and in the Colorado Desert, San Diego County. 

 Most of the records are from regions nearer to the coast, 

 where it has been taken in Los Angeles (Mt. Wilson, Arroyo 

 Seco, Sierra Madre at 1900 and 2500 feet, Eaton Canyon 

 near Pasadena, San Gabriel Mountains at 1700 feet, mouth 

 of San Gabriel River near Azusa, Claremont), San Bern- 

 ardino (east of Victorville, Cucamonga Canyon San Gabriel 

 Mountains, San Bernardino Mountains, Live Oak Canyon 

 near Redlands), Riverside (Banning, Gavilan, San Jacinto, 

 San Jacinto Mountains near Cabazon, Palm Canyon at 3,000 

 feet, desert seven miles south of Palm Springs), and San 

 Diego (San Diego, Witch Creek, Dulzura, Bonsall), coun- 

 ties.
