(Original description) The small, whitish shell is very slender..It contains one smooth turgid whorl in the protoconch, and six smooth normal subsequent whorls. The whorls are but slightly convex. The suture is very distinct, its posterior margin slightly overhanging or dominant. The aperture is narrow, short and simple. The outer lip is slightly concavely waved between the periphery and the suture. The siphonal canal is short, a little recurved and relatively rather wide.[2] DistributionThis marine species was found off Monterey Bay, California, USA.
