Rachis is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Cerastidae.[2]
This genus is also spelled as “Rhachis” as a synonym.[3] 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.[2]
