Description
The shell grows to a length of 22 mm.
The ovate, rather dark brown shell has a squat, fusiform shape. The eight whorls are slightly convex. The spiral sculpture shows shallow, well-spaced grooves. The axial ribs are rounded and number 11-14 per whorl. The shoulder angle lies below the middle of the whorl. The periphery is flattened so that body whorl is weakly biangulate. The aperture is rather large with a rather narrow, slightly notched siphonal canal. The color inside the aperture shows various shades of pale brown. The anal sinus is very shallow.[3]
Distribution
This marine species occurs from False Bay to Cape Agulhas, South Africa
