differs from the other species in having at the base of the mature body chamber, a drop-shaped conch cross section with a margin which is narrower at the dorsal side than on the ventral side. This difference could suffice to erect a new genus. However, nothing is known about the ontogenetic change of the conch cross section in this species, and it cannot be ruled out that the conch cross section is slightly deformed by taphonomic processes. More material is needed to evaluate the differences between this species and the

The conch surface is preserved near the base of the peristome, where it is smooth or with very fine growth lines, only. In lateral view, the conch margin at the antisiphuncular side is convex throughout the entire length. The prosiphuncular side of the conch margin is concave on the phragmocone and nearly straight on the body chamber. At the base of the body chamber, the conch height is

(CHI = 1.4). The conch cross section is rounded elliptical at mid body chamber position. At the base of the body chamber, the antisiphuncular margin is more narrow, almost rounded angular. In this latter specimen, traces of a fine transverse annulation are preserved, which is directly transverse, indicating that no hyponomic sinus occurs at the peristome. In lateral view, the antisiphuncular margin is convex and the prosiphuncular margin concave. The conch height decreases nearly continuously toward the aperture resulting in maximum conch heights at or near the base of the body chamber. The siphuncle is nearly marginal, but in all specimens is too poorly preserved to be measured in all specimens.

The form of the body chamber (curved, contracted) in combination with a marginal siphuncle is unknown from any multiceratoid genus. However, because details of the siphuncle and the phragmocone remain unknown a firm determination and erection of a new taxon is not possible with the available material.</paragraph>

On the adoral surface of the septa the adnate area is only developed ventrally. Thick endosiphuncular deposits are present. These are more strongly developed on the adoral side of the septal foramen than the adapical side. Hypo- and episeptal cameral deposits are restricted to the ventral side of the siphuncle.
