In the British Isles it lives in dunes, sandhills, and grassy downs close to the sea, chiefly in the south and west of
England,
Wales, on islands off the west coast of
Scotland, and along the
Irish coast. It is extremely abundant in some areas.[5]
This species does well on sandy calcareous soils, and often prefers a coastal setting such as sand
dunes. It
aestivates by attaching itself to vertical surfaces such as fence posts, tall weeds and so on.
Shell description
The
shell of this species is an unusual shape for a helicid, elongatedly conical, 10 to 20 mm high, with a width of only 4 to 7 mm. The spire tapers regularly, but ends in a blunt tip. The oval aperture has a thin lip, and the narrow umbilicus is almost covered.[5]
The shell is very variable in color and markings, often having a cream or off-white background with many pale brown blotches, which are sometimes organized into spiral bands. The shell is often streaked across the whorls with brown. There are sometimes two spiral bands of dark brown or black, which are frequently reduced to only one band, restricted to the body-whorl. Sometimes there are no bands at all.[5]
Welter-Schultes description.

gastropod shell
The 9-15 x 4-7 mm shell has 8-11 whorls, in juvenile specimens with a sharp edge. It is evenly white or with brown spots. The shell is less brownish, more slender and higher than the shell of Cochlicella barbara and upper whorls are slightly more rounded in C. acuta (juveniles have a much sharper edge at the periphery of the lowest whorl). The animal is very light yellowish, dorsum with blackish brown pigments, one dark medial line on dorsum, two dark lines (= retractor muscles) from the sides to the upper tentacles.[11]
