''Cerion'' is a genus of small to medium-sized tropical air-breathing land snails, terrestrial pulmonate gastropods in the family Cerionidae, sometimes known as the peanut snails. The genus is endemic to the Caribbean region. The name ''Cerion'' is based on the Greek word ''kerion'', signifying honeycomb, and is given to these shells because the form of the shell resembles that of a beehive; hence they were at one time known as beehive shells.〔Baker F. C. (1903). ''Shells of land and water; a familiar introduction to the study of the mollusks''. Chicago, A.W. Mumford, page 48.〕 The fossil range of ''Cerion'' is possibly from the Upper Cretaceous of Montana, or the early Miocene of Florida.〔("''Cerion'': a web-based resource for ''Cerion'' research and identification" ). accessed 5 April 2011.〕 Records of ''Cerion'' in Pleistocene are rare.〔 == Species == Species within the genus ''Cerion'' include: * ''Cerion acuticostatum'' Sánchez Roig, 1948〔("Mollusca" ).
