from Santa Margarita and Magdalena islands were identi- 

 fied by me at a time when S. zosteromus and S. rufidorsum 

 were regarded as identical. These specimens have been 

 destroyed and this identification cannot now be confirmed, 

 but it seems probable that they really were S. •zosteromus 

 rather than S. rufidorsum, for they all had from 18 to 22 

 pores. The lizard of Santa Catalina Island, a little farther 

 north, is certainly not S. rufidorsum (see S. lineatulus). 



Habits. — Mr. Slevin states that this species is strictly 

 terrestrial and extremely shy. It inhabited brush fences 

 around settlements and the heavy patches of brush in the 

 cactus belts.
