## Description

(Originally described in Latin as Spiroclimax) The shell exhibits a subcylindrical form, characterized by transparency and a suture that resembles a gently descending spiral staircase. The aperture displays an auriculate shape. The outer lip is thickened, featuring a sigmoidally margined profile that curves inward towards the suture. The columella is moderately thick, adorned with a funicular cord and exhibiting minimal plication. The protoconch is polished and positioned at a right angle.[2]
