This animal conceals itself under rocks and logs in moist places, but 

 has been found upon dry, elevated ground. The color seems to vary- 

 much with age, the young being much more thickly spotted than the 

 adult. In the specimens before me, this variation is not influenced by 

 locality. They hybernate beneath wet logs, and go into the water to 

 breed in April, in Georgia, and probably a little later in our limits.
