Bathyliotina lamellosa

Liotia (Arene) lamellosa Schepman, 1908 Bathyliotina lamellosa, commonly known as the spiny wheel shell, is a species of sea snail, a marine gastropod mollusk in the family Liotiidae.

It is followed by a whorl, with regular, distinct ribs, slightly angular at some distance from the suture.

These ribs have blunt spines, bordering the margin of the subsutural excavation, and sharper ones at the periphery.

The umbilicus is pervious, its margin strongly crenulated or folded, the folds entering the umbilicus and partly running upwards, towards the lower keel.

The whole exterior of the shell is covered by low, crowded lamellae.
