During the course of collecting trips made in 1976–8 two anthozoans, the actiniarian Aiptasiogeton comatus (Andres), and the octocoral Cornularia cornucopiae (Pallas) were found in Portland Harbour. Neither species has been previously recorded in British waters. A third species, Isozoanthus sulcatus (Gosse), was collected on the shores of the Gower Peninsula, South Wales. Since this species was last recorded in British waters in 1861 and its true taxonomic status is uncertain it is described here.
