 12% per cent. Tree Toads. 



This species belongs to the Eastern United Stales, being found 

 mostly east of the Alleghenies, especially near streams. It likes 

 to live in rocky woodlands, in shady, narrow, watered ^alleys and 

 to plunge into water when frightened. It is not poisonous nor 

 venomous, and in its feeding habits it preys mostly upon beneficial 

 Batrachians, and is consequently objectionable because tl)ese .ani- 

 mals are the enemies of obnoxious insecls. In our dissections only 

 four were found containing food and thi' analysis of their stomach 

 conlenis is as follows: (Mie sni'cinien conlained ( arthwornis only; 

 one contained a salamander, a tree frog, and fraginenls of insects 

 and 8i)iders; one conlained a snlamander and insecls, and the fourth 

 contained two salamanders, and insects. Keyond any reasonable 

 doubt all the insects and si)iders in the stomachs of these serpents 

 came from the batrachians which had eaten them previously to 

 the time of the snake making its meal upon the devourer of insects.
