SALAMANDERS. 373 



interesting animal, with peculiar habits and organization, 

 possessing, like his brotherhood, the powers of the chameleon 

 to a certain extent. It has a wide range, and is common on 

 the mountain. 



HYLA Pickeringia. Pickering's tree-frog. This frog is 

 found from Massachusetts to Pennsylvania. 



These batrachians live^upon trees, which they climb with 

 great facility by a special structure of the toes, which termi-

 down, suspending themselves like flies to the ceiling of a 

 room. They feed on insects, and their croaking voices are 

 well known to all.
