Alvania interrupta is an extinct species of minute sea snail, a marine gastropod mollusc or micromollusk in the family Rissoidae. [1]
This species is characterized by its irregularly-placed spiral ribs, these being crowded anteriorly, but almost absent posteriorly, so that spire-whorls have only two distinct ribs close to suture below. There are, however, traces of faint flattish ribs with linear interstices between these and suture above, and a distinct groove crosses ribs just below suture. [2]
