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 José 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.
