Description

This genus includes the thin-shelled light-colored species, previously included in Drillia [4]

The shell is generally short and stout, the spire often very short. The whorls contain nodulous axial ribs, extending over the whole of the volutions. They are generally without spiral sculpture, or, if present, very weak. The aperture is subrhomboidal, very little narrowed below, with a short and broad siphonal canal. The outer lip is arched, with a shallow sinus towards the suture. The inner lipis large and callous.[5]
