†Orthonychiidae is an extinct taxonomic family of fossil sea snails, marine, gastropod mollusks in the clade Cyrtoneritimorpha.[2]
There is an unusually great degree of variability within the shells of species in the genus Orthonychia,[1] but an analysis of this variability has not been done yet (2008).[1]
