Description
. Shell solid, polished, of average size for the genus, globose, pyriform, ventral surface rounded. Spire slightly protruding beyond last whorl, covered with thick callus. Posterior canal short, notched, sides thickened. Anterior canal very short, abruptly truncated, deeply incised. Aperture sinuous, widened above fossula; outer lip with 25–28 well-developed teeth, extending along entire lip; inner lip with 21– 25 well-developed teeth, extending along entire lip. Fossula well developed, subrectangular, concave, bounded on inner side by low ridge and anteriorly by sharp terminal ridge; terminal ridge rather broad, extending down into aperture as sharp ridge forming anterior edge of fossula.

Remarks
. This species is most closely similar to the living species
Zoila venusta
, from which it differs by having stronger teeth and teeth present along the entire columella. The fossula is also shallower but deeper within the aperture than in
Z. venusta
. It is not as globose, being more pyriform. It does not seem to be closely similar to the fossil species of
Zoila
known from the Oligocene and Miocene of southeast
Australia
.
Etymology
. Latin, fodina, a quarry.
