Description: Shell 8 • 3 mm x 4 mm. Four whorls are traceable. The last whorl shows a slight cingulum below the suture; shoulder well marked but not Urate followed by 5-6 weak spiral lirae, and then a strong lira about midway between shoulder and end of anterior canal, no lirae visible below this. No indication of axial ribs, but there are 2 or 3 very faint indications of possible granules on the shoulder. No sinus is visible, but the space between the subsutural cingulum and the shoulder is slightly concave. Growth-lines are not traceable. Columella without pleats.
