Material – 344 specimens.

Description – Shell moderately large (SL: 20–48). Spire low, outline concave to convex. Spiral whorls smooth or striate. Shoulder rounded. Body whorl broadly conical, outline convex, smooth with fine ridges at the base. Subsutural flexure asymmetrically curved. Colour pattern on some specimens consisting of spiral stripes of small blotches.

Remarks – The holotype, that was refigured by SACCO (1893, pl. 1, fig. 9), is missing; the neotype (SACCO l. c., pl. 1, fig. 16) was designated by HALL (1964). The species is generally characterised by a “fig-shape” shell with rounded shoul- der and low, convex spire, but it varies in size, outline of the spire, development of growth lines, and shell-width. Because of the intraspecific variability, lots of species and subspecies were assigned in the 19th century: C. broteri by DA COSTA (1866); C. daciae , C. vaceki , C. neumayri , C. voeslauensis , C. hungaricus by HOERNES & AUINGER (1879); most of them were revised by the above-cited authors. Beside D. berghausi , both D. moravicus (Hoernes et Auinger) and D. steindachneri (Hoernes et Auinger) are recognised here as valid species.
