Epitonium sp. aff. albidum (d’Orbigny, 1842)
Mayport Naval Station Beach, Duval Co, FL (8  mm.)
Also see: Epitonium albidum (d'Orbigny, 1842)

    Differs from typical form by appearing more sturdy, having thicker, more retroflexed costae which thereby twist at insertion on previous whorl, and by being smaller. Peristome more thickened and reflected; aperture almost completely rimmed. These shells closely resemble the form of E. albidum named Scalaria ligata C. B. Adams, 1850 (see Turner, 1956: pl. 21, fig. 3), Clench and Turner (1951: 262, fig. 3), and Andrews (1971: 84). Shells from the E. Atlantic identified as E. jolyi (di Monterosato, 1878) by Chiarelli (1996) may be this species. Also Lee, Collier, Pinellas, and Levy Cos., FL; LA, TX, and Brazil (Lee, 2009: 94; species no. 450).
