Distribution. — Santa Catalina Island, Gulf of California, 

 Mexico. 



Remarks. — This species resembles 5. zosteromus more 

 closely than it does S. rufidorsum and 5. fnonserratensis, to 

 all of which it is closely allied. Its femoral pores average 

 the same in number as in S. "zosteromus, and, like that species, 

 adult males have no distinct dorsal or dorsolateral light 

 streaks. It shares with S. zosteromus and S. monserratensis 

 the more or less parallel dark streaks on the lateral scales 

 which are absent in S. rufidorsum. It has not the numerous 

 light blue dorsal spots of S. monserratensis. 



Habits. — Like its immediate relatives, this species lives 

 on the ground in brushy situations.
