The height of the shell varies between 5.5 mm and 7 mm; its width varies between 10 mm and 13 mm.
The thin shell is fragile and translucent. It is turbinately globose, closely wound. The spire has a flat and conical shape. It contains 5½ whorls. The periphery of the last one shows a blunt ridge, that disappears before it reaches the aperture. The aperture is obliquely lunate. The umbilicus is very wide and measures about half the width of the shell.
