Material.
3 specimens Saal, SNSB – BSPG 2016 XXI 1713 –1715; 1 specimen Saal, “ Fundort 1985, über Korallenstock, Sohle 2 ” (= locality 1985, above coral stock, level 2), SNSB – BSPG 2016 XXI 1716.
Description.
Shell broadly turbiniform; illustrated specimen 18 mm high; mature whorls evenly convex with periphery at mid-whorl; sutures impressed; earliest preserved whorls have a pronounced edge below mid-whorl; whorl face between edge and adapical suture forms oblique ramp, vertical below edge; ramp initially with three, later with four spiral cords; shell below edge initially with one spiral cord, later with two spiral cords; edge becomes increasingly less pronounced and rounded on penultimate whorl; last whorl evenly rounded, markedly convex with periphery at mid-whorl and evenly rounded transition to moderately convex base; suture considerably deflected downward in last whorl so that another 4–5 spiral cords are exposed on penultimate whorl; 17 spiral cords are present on last whorl from suture to middle of base; all spiral cords are densely covered with small pustules; axial ribs absent, or only faint axial ribs on last third of last preserved whorl; base narrowly phaneromphalous; aperture circular.
Remarks.
The variability of this species could not be assessed, because only few specimens are at hand. The two best preserved specimens resemble those intermediate between variants 1 and 3 of Caryomphalus globatus sensu Gründel et al. (2020) .
