Original Description [Translation from the Russian.- Test oval, consisting of three whorls. Ventrally there are five chambers, the three final ones being oval-elongate from the periphery. Aperture large, semirounded, between the middle of the umbilicus and the periphery of the final chamber.
[Test relatively large, oval, conical. Dorsal side nearly flattened; ventral side strongly inflated. The final chamber is particularly well set-off. On the peripheral side, the chambers are oval-elongate, lobate. On the peripheral side the final chambers are oval-elongate,lobate.

Aperture large, gaping, not infrecuently nearly circular, exteding from the middle of the umbilicus almost to the peripheryof the final chamber.
