==Description==
The size of the shell varies between 14&nbsp;mm and 25&nbsp;mm. The imperforate shell has an obtusely turbinated shape. its color pattern is  fulvous, tinged with red at the base. Most of the specimens are strongly covered with incrustations, which render it impossible to count the whorls. The [whorl](/source/Whorl_(mollusc))s convexly slope next the [suture](/source/Suture_(anatomy)), then become tumidly rounded. They are longitudinally rudely ribbed with ribs irregularly wrinkled and tuberculated. The convex base of the shell is very closely irregularly scaled, with indistinct spiral lirae and fine radiating lamellae. The margin is more or less lobed. The [aperture](/source/Aperture_(mollusc)) has rose-colored margins. The interior of the aperture is grooved at some distance from the margin; only the groove corresponding to the keel, reaches the outer margin. The [operculum](/source/Operculum_(gastropod)) is externally very convex, with close-set granules, the margin is deep violet, especially the columellar one.<ref>[https://archive.org/details/prosobranchiaofs13sche Schepman 1908-1913, The Prosobranchia of the Siboga Expedition; Leyden,E.
