Liguus
''Liguus'' is a genus of large tropical air-breathing land snails, more specifically arboreal or tree snails, terrestrial pulmonate gastropod mollusks in the family Orthalicidae.
These snails are especially notable for their relatively large size, and for their often brightly colored shells, which sometimes have complex color patterning. Because of their visual appeal, the shells have been the target of heavy collection pressure — a serious issue since some varieties are very scarce, and some are believed to have become extinct within the 20th century.〔Power E.

==Distribution==
The genus ''Liguus'' is restricted to some of the Greater Antilles (Cuba, Hispaniola) and to Florida. Four of the species, ''Liguus virgineus'' (Hispaniola), ''L. blainianus'' (Habana and Pinar del Río Provinces, Cuba), ''L. flammellus'' (Pinar del Río Province, Cuba), and ''L. vittatus'' (Oriente Province, Cuba (1976, divided into five new provinces )), have localized ranges, while the numerous subspecies of ''Liguus fasciatus'' are more widely distributed, in both Cuba and southern Florida.〔
