6C60B3A1CA735D00B409C3A5C7128B42.taxon	diagnosis	Diagnosis. Austrocypraea jimgracei sp. nov. can be separated from all other members of the genus, fossil and extant, by a combination of the following characteristics: shell ovate to sub-pyriform, humped, highest point towards posterior, shell height around 71 % length, shell width around 59 % length; anterior extremity subtruncate, not extended in lateral profile, supported by well-defined anterior lateral flanges; protoconch paucispiral, spire projecting, overlain by callus. Aperture gently curved to the left posteriorly, widening slightly towards anterior; evenly spaced, relatively strong dentition; 13 - 17 columellar teeth, restricted to aperture, larger towards anterior; 17 - 21 labral teeth are longer, incised, and restricted to aperture margin. Fossula is broad, concave and smooth centrally, with shallow, barely discernible longitudinal depression or slightly raised ridge sometimes present; fossular margin with 4 - 6 denticles, visible in ventral view; anterior denticles not linked to adjacent columellar teeth by transverse ridges, but fine ridges may link posterior fossular denticles to adjacent columellar teeth. Columella smooth posterior to the fossula, lacking a defined columella ridge. Labral margin heavily callused, forming a distinct marginal edge, bent up towards the dorsum centrally; shallow anterior and posterior labral grooves may accommodate small, irregular, often elongate, pustules dorsal to the labral marginal edge; marginal edge may be weakly crenulate where marginal pustules intersect.	en	Southgate, Paul C., Roberts, Mike (2022): A new species of Austrocypraea (Mollusca, Gastropoda, Cypraeidae) from the Pliocene of Flinders Island, Tasmania.

6C60B3A1CA735D00B409C3A5C7128B42.taxon	description	Description. Average size for the genus (Table 1); shell length 23.1 - 25.5 mm (mean 24.5), W / L = 69 - 73 % (mean 71 %), H / L = 58 - 61 % (mean 59 %), H / W = 82 - 85 % (mean 84 %); ovoid to sub-pyriform, maximum shell height towards posterior; protoconch paucispiral, rounded; spire projecting, overlain by callus (Fig. 1). Shell formula: [24 (71 - 59 - 84) 19: 15]. Dorsal surface smooth except for weak longitudinal growth lines. Basal callus strongly developed; base rounded. Shell margins callused; left margin rounded, smooth; labral marginal callus well developed, with distinct marginal edge, bent up towards the dorsum centrally (Fig. 2 A); more sharply margined anteriorly and posteriorly, forming shallow labral grooves that may accommodate pustules or small tubercules, often elongate, dorsal to the marginal edge (Fig. 2 B, C). The right marginal edge may be slightly crenulate where pustules intersect. Anterior and posterior canals are deep and bordered by strong projecting callus; anterior canal with dorsoventral orientation, not angled; anterior terminal subtruncate, hardly extended, supported by anterior lateral flanges; anterior tips moderately pointed. Posterior canal short, bent to the left; bordered on the left by well-developed columellar callus, not extending as far as the posterior end of the labrum. Aperture gently curved to the left posteriorly, widening anteriorly. Fossula broad (Fig. 3), concave and constricted posteriorly; bordered anteriorly by a well-defined terminal pleat, thickening where it joins the terminal ridge. Fossula margin with 4 - 6 denticles becoming weaker posteriorly; anterior denticles not linked to adjacent columellar teeth by transverse ridges; poorly developed ribs may link the smaller denticles at the posterior end of the fossula with collumellar teeth, where the fossula merges with the columella (Fig. 3 B). Very weak ridges may extend onto the fossula from the marginal denticles and from the anterior-most columellar teeth, but they do not join; central fossula smooth, with shallow, longitudinal depression (Fig. 3 E) or slightly raised ridge on the central fossula sometimes evident (Fig. 3 A). A well-defined fossular gap is present at the anterior end of the fossula margin, between the anterior-most marginal denticle and the dorsal extremity of the terminal pleat. Columella lacks a defined columellar ridge and is smooth posterior to the fossula. Columellar teeth (13 - 17, Table 1) spaced about one tooth width apart; present along the length of the columella, terminating at the anterior edge of columella callus bordering the posterior canal; anterior columella teeth stronger, first tooth generally stronger than those posterior to it, and separated from the terminal ridge by a prominent anterior gap. Labral teeth (17 - 21, Table 1) restricted to aperture, longer anteriorly, more elongate and more numerous than columella teeth. Variation. Available specimens show variation in the angle of slope of the fossula, the number and form of fossular marginal denticles, and the presence, or otherwise, of a shallow depression or a slightly raised ridge on the central part of the fossula (Fig. 3). Pustules dorsal to the anterior and posterior labral margins may or may not be present or visible, and this probably relates to specimen maturity and the degree of preservation. Pustules may produce a weakly crenulate marginal edge in some specimens where (and if) they intersect. This feature is present in the holotype and its development is likely related to specimen maturity and the degree of callus development.	en	Southgate, Paul C., Roberts, Mike (2022): A new species of Austrocypraea (Mollusca, Gastropoda, Cypraeidae) from the Pliocene of Flinders Island, Tasmania.
