Original description: The last volution of the small to medium-sized low trochoidal test comprises 5-6 chambers. Umbilical and spiral sides are well-defined. About 2 whorls can be counted on the centrally slightly depressed spiral side. No details of the initial portion are discernible dur to the coarsely rugose surface. The ultimate chamber can be larger or of the same size or even smaller than the penultimate chambers of the last whorl are of conic shape. The adjoining chambers are peripherally rounded and truncate at the apertural side. The umbilicus is deep, usually filled with matrix. Remains of the delicate covering plate were noted. The straight sutures are depressed, thus producing a lobulate outline. The large arcuate aperture of the end chamber, with a small lip-like projection, opens into the umbilicus. The apertures of the preceding chambers are not known. The walls appear to be thick, and the surface is coarsely rugose. The rugosities of the inflated last chambers are arranged in meridional rows radiating from a center on the surface toward the edges fo the aperture. The investigated specimens are invariably dextrally coiling.

Plot of occurrence data:

Dec 2017 - Plotting of Neptune data has been re-enabled on the Mesozoic pages following revision of the age-models in Neptune. The data is, however, still very sparse for the Early Cretaceous
