Description

"The shell is elongated and fusiform and may appear biconic. The spire and bodywhorl have a distinctive rounded nodulated shoulder, that may become acute towards the anterior of the shell as the nodulation become finer, more acute and denser. The anterior canal is often well formed and acute in nature, being slightly reflected dorsally. The posterior of the bodywhorl is stained, and this staining continues to the dorsum, where it remains along the outer lip marginal fold and onto the dorsal whorl proper. The spire is always nodulated with the knobs varying from acute in some populations to more rounded and less pronounced in others. The aperture is margined in all cases with dark staining. The inner aperture with dark lirations over a rosy white base colour. The columella is midnight black, sometimes with some traces of deep plum that flush the posterior. The lirations of the columella while present, are in distinct" (Maxwell et al 2020).
