Material.
Specimen
MGUH
33182 consists of an internal and external mould of the lower half of the shell.
Occurrence.
The lithified top of the Højerup Member of the upper Maastrichtian Tor Formation at Højerup Church, Stevns Klint.
Description.
Protoconch unknown. Teleoconch whorls flat, separated by indistinct suture; whorl height corresponding to 2/3 the width. Aperture moderately high and narrow tear-shaped, the H/W ratio corresponding to 2.4 or just above. Inner aperture margin sigmoid with nearly straight columella.
Measurements.
MGUH
33182 is
2.85 mm
high and
1.25 mm
wide, consisting of three teleoconch whorls.
Remarks.
The taxon strongly resembles
Eulima
?
danica
(
Ravn, 1933
)
treated above, but differs through a relatively wider shell and aperture and a slightly more curved outline of the inner aperture margin. It resembles the Late Cretaceous
Eulima gracilistylis
Sohl, 1964a
and
E. persimplicata
(
Wade, 1926
)
from
Mississippi
,
USA
, but differs in the narrower aperture and a more slender outline.
