transverse, or elongate shells commonly without a well developed fold and sulcus. Brachial valve may bear a shallow furrow posteriorly. Ornament as in Atrypa. Dental lamellae present or obsolescent. Pedicle valve muscle field non-flabellate. Striated area for diductor attachment lacking in the brachial valve.Sockets not crenulated. A stout myophragm may be present. Brachidium as in Atrypa.
