Distribution.—This beautiful little snake was originally 
described from a specimen secured in the Mohave Desert. 
A few years later it was recorded from the Colorado Desert. 
In more recent years it has been collected, in California, in 
San Diego (La Puerta Valley and Carrizo Creek), Imperial 
(Calexico, Holtville, Meloland, Imperial, Pilot Knob), 
Riverside (Blythe Junction, grass fields between Blythe and 
Mecca), San Bernardino (Barstow), and Inyo (Owens 
Lake), counties. 
In Arizona it has been collected at Camp Mohave, Mo- 
have County, and Yuma and Chrystoval, Yuma County. 
Habits——Several specimens have been dug out from 
about one or two feet below the surface of desert sand dunes. 
This fact and the shape of the snout indicate burrowing 
habits. Beyond this nothing is known. It seems remark- 
able that a species which seems to spend its life underground 
should be so beautifully colored. 
Mr. Cowles notes a specimen found “traveling out in 
the open and in the heat of the noon sun, April 3, 1920. It 
was found on a gravel wash and when approached it struck 
in all directions, though apparently it did not open its mouth 
upon striking the hand. It appeared to be blinded by the 
sun and unable to tell from which direction it was menaced.”
