This shell has 5 to 6 whorls with a medium sized spire. It has about two large rounded varices on each shell whorl. It is sculpted by a series of alternating large and small spiral ribs that intersect axial folds. The inside of the outer lip of the aperture has a series of folds leading into the shell. These folds are often white while the rest of the inner aperture is a bright orange. There is a medium sized siphonal canal that is mostly enclosed and is often slightly curved. The outer shell is typically gray or white with lines and blotches of brown.
