Diagnosis

Reference	Diagnosis
C. W. Wright et al. 1996	Moderately to very involute; inner whorls typically with trapezoidal whorl section, rather sparse ribs, and bullate or spinate umbilical and clavate inner and outer ventrolateral tubercles; siphonal line may be slightly raised but venter normally lacking keel or row of siphonal tubercles. On outer whorl ornament may strengthen to extremes or may disappear. Suture tending to simplify.
