Distribution. — Santa Cruz and San Diego islands, Gulf 

 of California, Mexico. 



Habits. — Mr. Slevin states that lizards of this species 

 were numerous in rocky canyons and in the thick brush of 

 the dry washes. They were particularly abundant on a 

 small beach at the southwest end of Santa Cruz Island, 

 where they were feeding on the numerous flies attracted 

 by dead turtles and sharks left by the Mexican fishermen. 

 Five at six were seen here on the ground about a single tur- 

 tle shell. Up in a rocky canyon one was observed about 1 5 

 feet above the ground. It was on the top of a giant cac- 

 tus catching flies or bees which came to feed on the blos- 

 soms about it. When frightened, it immediately turned 

 head downward in one of the grooves of the cactus trunk, 

 steadied itself by pressing its long tail up against the sides 

 of the groove, and rushed down behind the spines.
