Abstract

The mother sporocyst, daughter sporocyst, cercaria and metacercaria of Cercaria cerastodermae I nom. nov. are described from the haemocoel of the digestive gland and gonad of Cerastoderma edule (L.) in Britain. The daughter sporocyst is unusual in having elaborate subtegumental projections that join a central broad chamber which extends to surround individual metacercariae.
