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.
