Abstract

Amphibious mollusks of the genus Cecina in the littoral and supralittoral of the Sea of Japan are represented by three species: Cecina manchurica A. Adams, 1861; C. tatarica (Schrenck, 1867); and C. scarlatoi Prozorova, 1996. Additional data on the morphology of the shell and radula are provided. Indices for the identification of adult decollated and corroded shells of these species which retained only 3.0–2.5 last whorls are proposed: (1) the ratio of the width of the ultimate whorl (without aperture) to the length of the ultimate and penultimate whorls and (2) the ratio of the width of the third whorl (from the bottom) to the width of the ultimate whorl (without aperture).
