Fig. 19H Material. Specimen MGUH 33082, representing a fragmentary mould. Occurrence. Lithified top of the Maastrichtian Højerup Member of the Tor Formation at Rødvig, Stevns Klint. Description. Shell low cap-shaped, apex located close to steep posterior margin. Protoconch 0.7 mm wide, obtusely conical to dome-shaped with at least 1.5 smooth whorls. Protoconch located at apex approximately 1/5 shell length from posterior margin, forming wide, somewhat bulbous beak over short, steep posterior margin. Adult shell thin, sub-circular, smooth, the only sculpture represented by weak, irregular growth lines. Measurements. MGUH 33082 is 2.6 mm long and 0.8 mm high. The width is unknown but seemingly nearly as great as the length. Remarks. This taxon differs from the typical Symmetrocapulus by the small size, lack of shell sculpture and the anterior location of the shell apex, and is consequently only tentatively assigned this genus. It may represent the youngest known species of this genus.
