In liis report oil tlie Eeptiles of the Death Valley Expedition Dr. 

 Stejneger remarks, " It can be asserted with confidence that Callisaurus 

 draconoides vcntraUs does not occur anywhere within the interior val- 

 ley of California, not even in AValker basin. Not is there aiiy evidence 

 to show that it occurs anywhere southwest of the San Bernardino 

 range, within the boundary of the State of California." 



Dr. Merriam ^ gives the following descrijition of the habits of Calli- 

 saurus draconoides ventralis : 



The gridiron-tailed lizard is the most characteristic reptiJe of the Lower Soiioran 

 deserts of soutberu California, southern Nevada, southwestern Utah, and Arizona, 

 whore it is almost universally distributed and very much more abundant than any 

 other species. It iuhabits the open deserts and runs with great swiftness over 

 the sand and gravel beds, carrying its tail curled up over its back as if afraid to 

 let it touch the hot surface of the earth. It starts off at full speed, as if fired from 

 a cannon, and sto^is with equal suddenness, thus escaping or eluding its enemies, 

 the coyotes, hawks, and larger lizards. When running it moves so swiftly that the 

 eye has difficulty in following, and when at rest its colors harmonize so well with
