Epitonium

Wentletraps

Wentletraps (Epitonium) are delicate white spiral shells with raised axial ribs like a spiral staircase, the precious wentletrap Epitonium scalare being the most famous and, in the 18th century, so valuable that rice-paste fakes were made. Genuine specimens today are affordable. Ribs and intact apex set the grade.
