Range — Auversian, Bartonian, Ypresian and Lutetian Eocene of France.

Shell of moderate size, 12-18 mm., narrowly fusiform, with a tall spire, and an elongated body-whorl, produced into a moderately long, slightly flexed, and weakly notched anterior canal. Protoconch very small, narrowly conical, of 1 1/2 smooth whorls, the tip off centre. Adult whorls broadly bluntly carinated at or below the middle, on the spire whorls. Sculpture consisting of numerous flexuous axial folds, which commence strongly at the suture, diminish over the shoulder sulcus, and become very strong, as crescentic nodes, over the peripheral carina, after which they fade out over the base. The whole surface is crossed by weak spiral threads which become stronger over the base. Sinus moderately deep, widely open, its broadly rounded apex peripheral, and extending a little above the carina.

The genus was compared with Bathytoma by its author but the relationship appears to be nearer to Eopleurotoma.
