The calcareous structures of the triplesiaceid shell are discussed and interpreted in terms of the soft parts of the living animal. Special attention is paid to the pseudodeltidium, the pedicle tube, the muscle scars and pallial sinuses, which have received little consideration in the past. Relationships of the superfamily to other brachiopod stocks are considered. A new species of Cliftonia, C. oxoplecioides, from the Ashgillian, the earliest known for that genus, is described.
