Its color is white covered by a very light olive gray periostracum. The suture is distinct. The fasciole is hardly impressed. The spiral sculpture consists of obscure striae, sparser on the base. The axial sculpture consists of incremental faint lines arcuate on the anal fasciole. The aperture is narrow. The anal sulcus is wide and moderately deep. The outer lip is thin, prominently arcuate in front of the periphery. The inner lip is erased. The columella is strong with a single fold near the body ; attenuated in front. The siphonal canal is short. The height of the shell is 16 mm ; of the body whorl: 10 mm; diameter: 6 mm.[2] DistributionThis species occurs in the Pacific Ocean off Santa Barbara Island, California.
