Hal)its rntfl Hahitat: The green frog is thoroughly nquatic in its 

 habits, never travelling far from the water. It may be found along 

 the edge of small streams, pools and cold springs. It is rather 

 solitary and timid, wlien frightened disappearing quickly in the 

 water. It is very much like the bullfrog in appearance and habits, 

 but mav be readilv distinguished bv the lateral folds and the smaller 

 webs on the feet. The food consists of insect larvae, small crusta- 

 ceans, small frogs and insects. It comes early from hibernation. 

 The song, which is low pitched and explosive in character, is usu- 

 ally heard in March. The eggs are laid in April, in large masses 

 supported in the water by twigs or water plants. The early develop- 

 ment is rapid, but metamorx)hosis is delayed till the second summer 

 and sometimes the third. Hay (1892a) states that the tadpoles 

 are vegetarians and never carnivorous.
