Remarks

Dall (1905b:33) reported:  "This is a large, heavy, variable species with a peculiar thick duplex sharp-edged lip.  The shell varies from nearly smooth to rather finely and closely rib-striate.  An imperfectly preserved form resembling this species was obtained from the narrow part of Eleuthera Island, opposite Savanna Sound, at Station 18, and another on the same island about two miles north of Governors Harbor, at Station 1."

 

Gould et al. (1985:1368) report a sinistral C. fordi, which they regard to be "an invalid name for the Cat Island population of the relict C. agassizi stock, a widespread Pleistocene fossil of the northern Bahamas, now surviving in small areas of Eleuthera and Cat Island (and to historical times on the southeastern corner of New Providence)."
