THE BRACKISH WATER bivalve Rangia cuneata Gray, 1831, a member of the family Mactridae, has been reported from Virginia estuaries in the past few years. This species, until recently common only along the Gulf Coast, occurred in estuaries from New Jersey to Mexico during the Pleistocene ( RICHARDS, 1938) , and now seems to be reoccupying its former range. Live R. cuneata on the east coast were first reported from North Carolina in 1955 (WELLS, 1961), Florida in 1961 (WOODBURN, 1962), Virginia in 1960 (WAss, 1972), the Potomac River in 1964 (PFITZENMEYER & DROBECK, 1964), upper Chesapeake Bay in 1966 (PFITZENMEYER, 1970), and the Elk River, Maryland, in 1968 (GALLAGHER & WELLS, 1969). The most common explanations of the range extension of R. cuneata have been reviewed by HOPKINS & ANDREWS (1970).
