To study the Far East gastropod Nucella heyseana (Dunker, 1882), 15 samples were collected in the northwestern region of the Sea of Japan from Pos'et Bight of the Peter the Great Bay in the south to the Valentin Bight in the northeast of Primorye. The genetic variation for four to ten polymorphic allozyme markers and the morphometric variation for five shell traits were analyzed. The interspecific genetic differentiation (as compared with the interspecific variation in sympatric regions) and the comparative between-year variation clearly showed that genetically uniform, thought subdivided, populations occupy each region of a particular bight and groups of regions within the area under study. In total, three local populations were observed in the area; their morphometric differentiation was consistent with their genetic structure.
