Abstract

P. gemellipara is reported from its type host Geukensia (=Modiolus) demissa and from two new hosts Ischadium (=Brachidontes) recurvum and Mytilopsis (=Congeria) leucopheata . Its range on the Atlantic seaboard is extended from Woods Hole, Massachusetts south to the lower Chesapeake Bay. The worm is also reported from the Gulf of Mexico at Galveston Bay, Texas. The presence of dermal protuberances and posterior adhesive areas bearing mucous strands is recorded. Mature worms were found living in the digestive tract of their host, contrary to the findings of previous investigators who reported them from the gill and kidney
