Distribution. — Cnemidophorus bacatus occurs on San 

 Pedro Nolasco Island, in the Gulf of California, Mexico. 



Habits. — This beautiful lizard was not common. Most 

 of the specimens taken were found around the nests of a 

 colony of brown pelicans, where they were seen catching 

 flies and the numerous insects attracted by the dead fish 

 and refuse. A few were found among the fallen cacti in 

 the deep gullies which run down to the sea coast.
