98 HERPETOLOGY OF MICHIGAN. 



hopper, striped brown cricket, undetermined ground beetles, unde- 

 termined vertebrates, undetermined fish, catfish, white sucker, 

 Cottus ictalops, Cottiis ricliardsoni, undetermined salamander, 

 Plethodon cinereus, tadpole, toad, green frogs, undetermined mam- 

 mals, meadow mouse (Microtus pennsylvanicus) , common shrew 

 (Sorew persoiiatus) . Atkinson (1901, 150) says that it feeds upon 

 "crustaceans, fish, and batrachians." De Kay (1842, 42) found it 

 feeding on the lake lamprey, bullhead, brook trout, and white 

 sucker. Blatchley (1891, 30) removed seven leopard frogs from a 

 single specimen. Ortmann (1906, 495) states that crawfish form an 

 important part of the diet of this snake. Notwithstanding the 

 variets^ of food which it is thus evident that the watersnake will 

 eat, fish form by far the greater part of the diet. In the few 

 stomachs which we have examined from southern Michigan speci- 

 mens, small fish alone were found, and these often in considerable 

 numbers.
