Claiborne Bluff, Alabama River, Alabama, USA; stratum: Gosport Sand (uppermost Claiborne Group); age: Eocene.

Type material.

Syntypes, ANSP IP30547 (as “lectotype” in Palmer 1937: 500; as “lectotype?” in Moore 1962: 65), 1 shell, ANSP IP53814, 5 shells (all as “syntypes” in Richards 1968: 144). The designation as lectotype by Palmer (1937) is likely mistaken ( Moore 1962; Richards 1968).
