''Cochlicella acuta'', common name the pointed snail, is a species of small but very high-spired, air-breathing land snail, a pulmonate gastropod mollusk in the family Cochlicellidae. Previously however, ''Cochlicella'' was placed in the Helicidae or the Hygromiidae instead. ==Distribution== This species is native to parts of Europe. It inhabits south-western Europe including Spain, and western Europe including France, Belgium, Netherlands〔http://www.anemoon.org/anm/voorlopige-kaarten/kaarten-per-soort/landmollusken/wetenschappelijk/cochlicella-acuta/, accessed 25 September 2008〕 and the British Isles.〔Kerney M.P. & Cameron R. A. D., 1979. ''A field guide to the land snails of Britain and northwestern Europe'', Collins, London.〕 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.〔Step E. 1901. (''Shell life: an introduction to the British Mollusca'' ). London, New York, F. Warne & co., page 362.〕 The species has been introduced in the eastern Mediterranean, including Greece,〔http://www.firama.com/landsnails2/2455/index.asp〕 Israel and Egypt.〔Commonwealth of Australia. 2002 (April) (Citrus Imports from the Arab Republic of Egypt.
