Habits and habitat. — More has been recorded of the habits of this 

 snake than of those of most of the forms of Pituophis, but in consider- 

 ation of its great abimdance in California it is surprising that so little 

 is actually known. 



Hallowell (1853, p. 236; 1859, p. 15) says the type specimen of 

 "heermanni" "came from the mines, in the vicinity of the Consumnes 

 river; one specimen was found under a log, and Dr. Heermann found 

 several basking in the sun, during the middle of the day, on the banks 

 of streams, in sandy and gravelly places." 



Girard says of the genus (1858, p. 134), with special reference to 

 catenifer: "They are of terrestrial habits. Quite timid in spite of their 

 great size."
