Town Creek and vicinity (* = known range of Helisoma eucosmium, ? = known sites of Planorbella magnifica. (1945) designation pending definitive studies of soft tissue anatomy. Over much of its length, Town Creek is a tidal system approximately 30-50 m wide with maximum depths varying between 5-7 m. Whereas the lower reaches are brackish, no salinity has been detected in the area where Helisoma eucosmium occurs. Physical parameters of the water are pH (* = , n = 3), conductivity 217 //mhos/cm (n = 2), and calcium concentration ppm (n = 2). All specimens of H. eucosmium came from a littoral community, occurring in less than 3 m of water, consisting of dense continuous mats of Brazilian elodea (Egeria densa Planchon), fanwort {Cabomba caroliniana Gray), fragrant waterlily (Nymphaea odorata Aiton), spatterdock (Nuphar luteum (Linnaeus)), and floating-heart (Nymphoides aquatica (Walter))..
