The clam Polymesoda caroliniana (Bosc), which ranges north and eastward in brackish waters from Lavaca Bay, Texas,2 has not pre- viously been reported north of the Neuse River, N. C. (Van der Schalie 1933). On 7 April 1947, Richard Hoffman found several shells on the beach above Swann Point on the James River, a tributary of Chesapeake Bay (Fig. 1). On 20 April 1947, J. P. E. Morrison (personal communication) and Hoffman found living specimens in the mud and detritus around the knees of cypress trees one-half mile above Swann Point. These records are included in this paper through the courtesy of Dr. Morrison of the U. S. National Museum.
