Rhynchotrochus rollsianus
Rhynchotrochus rollsianus is a species of land snail in the family Camaenidae.
It was first described by Edgar Albert Smith in 1887 as Helix rollsiana.
A later redescription of a specimen from Ferguson Island in the D'Entrecasteaux Archipelago, is given by Wilhelm Kobelt and others. In 1941 Tom Iredale ascribed it to the new genus, Volenga, to give the new name Volenga rollsiana.
