It is bright green, longitudinally strigate with white under a brown epidermis.

The color pattern is sometimes unicolored green, or with the white strigations broken into tessellations.

The upper ones are sometimes angulate, spirally lirate with the lirae wider than their interstices, on the body whorl often subobsolete.

The columella has a very wide white flattened callus which extends over the umbilical tract.

The species is a dominant feature of shell middens in southeast Australia, archaeological sites created by humans consuming the animal.
