Moelleriopsis Explained

Moelleriopsis is a genus of sea snails, marine gastropod mollusks unassigned in the superfamily Seguenzioidea.

Description

The small shell of these deep-water species is relatively thin. It is white under a golden brown or olive brown epidermis. It contains few, convex whorls, forming an elevated spire and large body whorl. The suture is distinct. The round and deep umbilicus has a moderate size, showing some of the whorls. The circular aperture is slightly oblique. The peristome is continuous with a thin, sharp edge, appearing thickened within. It is attached to the body whorl only for a short distance.^[1]
