"Euhadra" is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Bradybaenidae. (This snail genus was previously placed in the family Eulotidae).

A few of the species in this genus are unusual in that specimens in those species always have left-handed "sinistral" coiling in their shells, as shown in the specimen on the right. The rest of the species in the genus are right-handed or "dextral" in the shell coiling, as is usually the case in the great majority of gastropods.

Distribution

These snails are endemic to Japan.
