Habits. — The snakes taken at Elko, Nevada, had been 

 feeding on the larvas of Rana pipiens. 



Ruthven and Gaige, who observed this snake in Elko 

 County, Nevada, state: "The species is quite aquatic in its 

 habits. It is generally found in the immediate vicinity of 

 water, and often in the streams or ponds. From the stom- 

 achs examined it would appear that most of the food is 

 secured in the water. One specimen had eaten a small toad, 

 and five others had captured fish and tadpoles. It is a 

 voracious feeder. The stomach of one individual contained 

 eight large tadpoles, that of another five fish, and one had 

 eaten a fish 141 mm. in length besides a smaller one. Three 

 pregnant females brought back alive gave birth to eight, 

 ten and 12 young on August 25, September 2 and Sep- 

 tember 1 0."
