Campanile sp. B

Fig. 24G

Material. Specimen MGUH 33143 is an external whorl mould.

Occurrence. Lithified top of the Maastrichtian Højerup Member of the Tor Formation at Holtug Quarry, Stevns.

Description. Teleoconch whorls flattened, slightly sigmoid in outline with sharp, pronounced abapical keel and weakly convex base. Suture deep. Columella with sharp, nearly horizontal fold. Teleoconch sculpture fairly coarse, consisting of spiral ribs and coarse tubercles on keel and finer beading on spiral rib 1/3 of whorl height from adapical suture; weak, slightly prosocline transverse ribs reaching adapical from spiral beads to suture.

Measurements. Whorl height 3.4 mm.

Remarks. MGUH 33143 differs from the two taxa described above by the deep suture and the prosocline transverse adapical ribs. The strong differences suggest that the taxon should be regarded as a separate species.
