Description
The length of the shell attains 4 mm, its diameter 3 mm.
(Original description in Latin) The rather solid shell has an conoid-globose shape and is imperforate or rimose (having a chink). It is finely striate, shining with an oily tinge, scarlet with the superior whorls often turning whitish. The spire is cone-shaped, with convex sides and an sharp apex. The suture is impressed, and it is not margined. It has 6½ convex whorls, which are much larger. The body whorl is swollen and rounded below. The aperture exceeds the height of the spire, and it is nearly vertical, and acutely angled above. The peristome (margin) is straight, with a thin outer lip. The inner lip is slightly thickened and expanded. [2]
