Rachis is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Cerastidae.
This genus is also spelled as “Rhachis” as a synonym. Rachis is a Latinised version of rhachis (a midrib or ridge) or rhachos (a thorn or thorn bush), both of which are Greek nouns of feminine gender.
