Fig. 24L Material. Specimen MGUH 33146 is a fragmentary teleoconch mould. Occurrence. Lithified top of the Højerup Member of the Maastrichtian Tor Formation north of Kulsti Rende. Description. Teleoconch broadly coeloconoid with weakly convex, nearly flattened whorls with a strongly angular abapical keel and separated by somewhat grooved sutures. Whorl height approximating 2/5 the width. Base weakly convex. Columella smooth with no columellar fold. Whorls subrectangular in cross section. Early teleoconch sculpture consisting of 12 to 18 coarse transverse ribs and fine spiral lirae. Transverse ribs reaching from adapical two spiral lirae and abapically to keel. Later teleoconch whorls smooth except for two weak adapical spiral lirae and two similarly weak abapical spiral lirae located slightly adapically of keel. Growth lines strongly prosocline, slightly prosocyrt. Measurements. Specimen MGUH 33146 is 7.2 mm high and 6.0 mm wide, consisting of 6 ½ teleoconch whorls. Remarks. The Danish taxon resembles the late Maastrichtian D. chukinensis Kaim, Beisel & Kurushin, 2004 from Western Sibiria, but differs by the concave sided spire, the more flattened whorls with the abapically located keel and by a less convex base.
