Calliotropis View in CoL spec. 1

( Figures 35–36 View FIGURES 33 – 38 )

Material. Anda 1 (1); Anda 2 (2); Anda 4 (2).

Characterization. Shell with rounded whorls, H 0.7 mm, W 0.8 mm; P large, bulbous, granulate, 1.1 whorls, DN 0.22 mm; P/T boundary distinct rib; T with reticulate ornamentation; weak spines on intersections of spiral and axial ribs; microsculpture of discontinuous granulate spiral threads; body whorl with four spiral ribs; aperture rounded; umbilicus moderately wide.

Remarks. These shells are probably all juveniles of a single species that could not be matched with any of the other Calliotropis species in the studied material. It is most similar to C. limbifera ( Schepman, 1908) , but the spiral ribs are placed lower on the whorls in these specimens than in C. limbifera ( Schepman, 1908) , the microscopic threads are spirally instead of axially arranged and the protoconch is less inclined.
