Bathybembix View in CoL ? sp.

Fig. 21I View FIGURE 21

Material. Specimen MGUH 33101, a natural mould of parts of the last whorl.

Occurrence. The specimen comes from the lithified top of the Maastrichtian Højerup Member, Tor Formation, in Holtug Quarry.

Description. Last whorl convex with at least four sharp, beaded spiral ribs interconnected by oblique, discontinuous and sharply narrow transverse cords. Beading on keel rib spiny, becoming less pronounced on base ribs and adapical rib. Beading on adapical spiral rib much finer and more densely spaced than following ribs.

Measurements. The whorl fragment is 3.65 mm wide.

Remarks. The sculpture and whorl profile is very similar to that of the extant Bathybembix bairdii ( Dall, 1889) , which is why the present taxon is tentatively assigned here in spite of a current oldest generic record from the late Eocene (see Hickman & McLean 1990). Better material, though, may still lead to a reassignment to Solariella or perhaps Pareuchelus .
