Argyrotheca altavillensis and A. cf. semicostata are reported for the first time from Great Britain. They occur in the Bracklesham beds at Selsey, Sussex. Terebratulina edwardsi, previously known only from a young specimen, is now described from an adult form found in the same material. British Eocene brachiopods are listed, and the ecologic significance of their rarity and distribution is noted.
