( Figures 30–32 View FIGURES 26 – 32 )

cf. 2007 Calliotropis pyramoeides nov. spec.—Vilvens: p. 36, figs 112–115.

Material. Anda 1 (20); Anda 2 (19); Anda 3 (11); Anda 5 (4); Anda 6 (5); AndaDeVos (4); AndaClif3 (3); Tiep 1 (1).

Characterization. Shell broadly conical, H 2.8 mm, W 2.9 mm; P globular, finely granulate, with four discontinuous spiral ribs and zigzag patterns, 1.1 whorls, DN 0.17–0.18 mm; P/T boundary thin rib; T ornamented with spiral and axial ribs with spines at intersections; spines lower on whorl develop into C-shaped lamellae; umbilicus broad, encircled by rib, with spiral and axial ribs inside.

Distribution. South-western Pacific ( New Caledonia area), alive at 200 m depth, empty shells at 250–350 m depth ( Vilvens 2007), apart from the studied material.

Remarks. The base of our shells appears to be taller than those figured in Vilvens (2007).
