holes hollowed out of the rock by stream action, and shaded by sur- 

 rounding cliffs. 



The desert terrestrial animals are for the most part independent 

 of water ; those apparently needing it, during the summer at least, are : 

 coyotes, foxes, badgers, bob-cats, bighorn, and quail. The animals 

 which fly to the water holes are perhaps more numerous, and include 

 the bats, most birds, bees and wasps. 



The following table indicating the environmental distribution of 

 reptiles in the Turtle Mountain vicinity shows how sharply marked in

Note. — Large crosses mean abundant; two small crosses, fairly common; one 



small cross, rare. Small numbers opposite crosses refer to number of individuals 

 upon which the generalization is based. A question mark (?) means that these 

 species occur elsewhere on the desert in this environment and may do so in 

 the Turtle Mountain region.
