The others show axial plicae that are a little arcuate and become sigmoid on the body whorl. The aperture is rather wide and lacks a siphonal canal at its base. The columella shows a callosity that becomes rather thick at the top. The outer lip is incrassate, bends off inwards and ends at the top into a large and deep sinus. The color of the shell is white, banded in the upper whorls by a series of brown spots between the axial plicae.
