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 International Code of Zoological Nomenclature

Description

The genus includes Aporrhaidae shells with three long, thin finger-like extensions from the apeture
Aperture (mollusc)
The aperture is an opening in certain kinds of mollusc shells: it is the main opening of the shell, where part of the body of the animal emerges for locomotion, feeding, etc....

. The original description described the shell as having (translation from the French), "a semi-palmate lip, three digits, the posterior one of which is weakly attached to the spire, inner lip of columella thick, and siphonal canal bent or curved at the end". The type species for the genus is Cuphosolenus tetracer (D'Orbigny).

Distribution

Cuphosolenus has been reported from the Jurassic of France, the Sinai, and questionably from Saudi Arabia, as well as the lower Cretaceous of Texas and Mexico.
In his 1891 work, Piette included descriptions of 16 species of Cuphosolenus from the Jurassic of France.
