( Figures 2–3 View FIGURES 1 – 5. 1 )

2012 Sinezona marrowi   nov. spec.—Geiger: p. 500–503, figs 379–381.

Material. Anda 1 (1) RGM 961.706, Tiep 2 (1) RGM 961.707.

Characterization. Shell with flattened apex and inflated base; H 0.80 mm, W 1.04 mm; P with axial sculpture, DN 0.06–0.09 mm; T 1 with strong prosocline axial lamellae and fine spiral cords; axial lamellae weaker on T 2; aperture large, inclined; umbilical wall straight; umbilical ridge thin but prominent.

Distribution. Indian Ocean and Indo-Malayan Archipelago, 0–434 m depth (Geiger 2012).

Remarks. The studied material conforms to the description by Geiger (2012), except for the umbilical ridge, which appears to be more prominent in the studied material. The development of the slit cannot be observed in this juvenile material.
