The surface is lustrous where rubbed, ornamented with a single conspicuous carina which defines a broad, flattened sutural area and makes the whorls slightly angulated.

On the base surrounding the umbilicus there are also four more prominent carina, about equal in size and evenly separated by wide, slightly concave interspaces.

At their termination they form distinct points on the somewhat expanded thin edge of the peristome.

The aperture within is dull, opaque white, with a narrow, much thinner, semi-transparent, somewhat expanded, sharp-edged border.

This gives the appearance of thickening, but there is no raised opaque white line, said by some author to be the distinguishing character of Moelleria.
