Shell small, with 8 to 9 whorls, and flat sided, with sutures being slightly impressed. Two channels on upper whorls and four on the body whorl are crossed by axial ribs, giving the shell a beaded appearance. A distinct rib is present on the body whorl of adult shells.

Locally, numbers of about 500 individuals per square meter can occur. Usually living in the upper bottom layer of mud which is almost liquid (Ref. 349). Detritus feeder (Ref. 751).
