The umbonal areas are not preserved, but the specimens are apparently quite large, the largest fragment measuring 135 mm in height. Preserved parts of moulds are more or less flat, with spaced commarginal folds, the distance between folds increasing ventrally. The folds are slightly asymmetric in cross-section, the ventral flank being steeper. Areas with preserved shell material show that the shells were very thin.</paragraph>
