Description
The length of the shell attains 12 mm.
(Original description) The slender pyramidal shell is acuminated. It is six-sided, horny brown, longitudinally ribbed, crossed with raised striae, somewhat rugose and with smooth interstices. The shell contains 7-8 flattened whorls. The suture is opaque. The sculpture is much plainer on the body whorl. The inner lip shows a thin deposit of callus. The outer lip is thin, edged with black. The sinus is wide, cut deep down. The siphonal canal is short.[2]
