Name : Southern stone crab. 



Diagnostic characters : Large, with huge chelae ; shell very heavy, 

 mottled moss green, fingers tipped with black. 



Type : Say 's type description merely states that the species inhabits

 Sciences.

 rocks during the day and does most of its foraging at night. 



Material examined: One specimen, taken in the Bay Biscayne,
