In the course of a study by Gibbs (1984) of the reproductive biology and the population dynamics of the bivalveAbra tenuis(Montagu) collected from the Fleet, a brackish water lagoon in Dorset, and from the Plym Estuary, Plymouth, a number of species of apparently pathogenic larval digeneans was found. These could not be satisfactorily identified from their larval characters alone, and following collaboration with Professor J. Llewellyn (personal communication) it was decided that they should be made the subject of a further study.
