In eastern Massachusetts I have always found this species inhabit- 

 ing different territory from that frequented by the painted turtle 

 (Chrysemys field). The latter is a species of ponds and rivers. 

 Clemmys guttata, on the contrary, is found chiefly in wet woods, 

 marshes, or shrubby ground traversed by brooks or ditches, and is 

 much more easily captured than its shyer relative.
