The living terebratellid brachiopod Bouchardia rosea (Mawe), from the southeast Atlantic Ocean, has an unusual internal morphology; both valves are so heavily thickened posteriorly as almost to fill the space, leaving room only for the pedicle, its posterior adjuster muscles and the diductor muscles. These structures are here described in functional terms for the first time and, with the help of partial dissection of the soft tissues, the true nature of the musculature is revealed. Despite its unusual aspects, cardinalial structures of the dorsal valve can be interpreted in terms of those more commonly found in terebratellids.
