Fig. 27X Material. A single very fragmentary specimen, MGUH 33202. Occurrence. Lithified top of the Maastrichtian Tor Formation just south of Højerup Church at Stevns Klint. Description. Teleoconch whorls flattened, twice as wide as high and separated by rather indistinct sutures. Base flattened. Columella smooth without folds. Sculpture consists of three moderately weak spiral ribs with strongly developed, rounded tubercles numbering around 16 per whorl. Transverse sculpture only present in the form of a weak, opisthocyrt organization of the tubercles. Measurements. MGUH 33202, consisting of two teleoconch whorls, 0.65 mm high and nearly 0.6 mm wide. Remarks. The specimen strongly resembles the Danian Cerithiopsis subcylindracea ( Briart & Cornet, 1873 ) from Belgium with which it may be conspecific. The Danish taxon is kept under open nomenclature due to the extremely poor material and the slight stratigraphic separation.
