Figures 16KâL, N
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 25â28 well-developed teeth, extending along entire lip; inner lip with 21â 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.
Dimensions.
Type locality. Quarry 2.5 km north of Hampton microwave repeater tower, Roe Plains, Western Australia. AMG Eucla l:250,000 sheet CK365465. Roe Calcarenite .
Type material. Holotype, WAM89.637, collected G.W. Kendrick, 27â30 October 1988.
Time range. Pliocene
Occurrence and material. Roe Calcarenite: PL3166 2.5 km north of Hampton Tower (one specimen) .
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.
