Spelling

In 1887, Paul Fischer “emended” the spelling of the name to ''Cyphosolenus''. In 1891, Piette accepted Fischer’s use of ''Cyphosolenus'' in the text of ''Paléontologie Française ou Description des Fossiles de la France'', etc., Vol. III (text), p. 376 ff. This change in spelling has been described as an unjustified emendation under the rules of the

The genus includes Aporrhaidae shells with three long, thin finger-like extensions from the
