Key Identification Features
- Each whorl also features regular, coarsely sculpted rows of fine knobs and folds.
- The outer surface of the operculum is white, very convex, and has indistinct obsolete rugosity.
- The main body whorl has 20 distinct, mostly flat-topped spiral ribs, some of which have fluted scales.
- Two distinct morphs exist: a smooth morph, which only has growth striae near the lips, and a spiny morph, which has two rows of open-fronted spines on the body whorl.
