Laxispira sp.

Fig. 27O

Material. MGUH 33193, an external mould in the unformally catalogued sample SH.3.B–C, and a last mould without number in the old collections at the Natural History Museum of Denmark.

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

Description. Protoconch not known. Teleoconch loosely coiled with round aperture and apparently without keel. Shell sculpture of well defined, densely spaced granular spiral ribs crossed by densely spaced growth lines. Spiral ribs may become slightly coarser on abapical side of whorl.

Measurements. Largest specimen with aperture diameter of 11.3 mm.

Remarks. The taxon has a strong resemblance to the Maastrichtian L. libycus Quaas, 1902 from Egypt and the Late Maastrichtian L. pinguis Holzapfel and L. cochleiformis (Müller) from Holland as figured by Wenz (1939), but differs by its strongly and evenly beaded spiral ribs. It also resembles Laxispira monilifera Sohl, 1964b from the Late Cretaceous of Mississippi, but differs by a more evenly beaded spiral sculpture.
