merous lizards found in the cactus belt. One specimen had 

 a full grown Dipsosaurus in its stomach. Another had 

 eaten a Cnemidophorus, and another, a mouse. A fourth 

 had the tail of a Dipsosaurus in its stomach. A fifth was 

 taken in a brush pile just after it had caught a Verticaria. 

 The tail of the lizard was protruding from the snake's 

 mouth. A specimen taken at San Jose del Cabo was six 

 feet in length. A cactus spine over an inch long was pulled 

 out of a specimen taken at Miraflores. 



Mr. Slevin found one near Blythe, Riverside County, 

 California, about six feet up in a mesquite where it was 

 swallowing a young dove which it had just removed from 

 the nest.
