Description

edit

The minute shell is oliviform, smoother microscopically spirally striolate, mainly on each side of the sutures, leaving the central portion of the whorl plain, in form cylindrical or elongate, compact, only slightly impressed at the sutures. The whorls of the protoconch are closely and very finely cancellate. The whorls are semi-pellucid, unicolorous white, or flecked with pale stramineous. The aperture is narrowly oblong. The outer lip is nearly straight, slightly thickened,. The sinus is hardly expressed.[2]
