Critical review of stylommatophoran mollusks of the fauna of Vietnam. The Check-list includes 477 species and subspecies (96 genera, 20 families). For every species (subspecies) references to original description, synonymy, type locality (in original spelling) including synonyms, shell dimensions (for slugs – body length) and distributional data are given. In the end the index of mentioned molluscan names and the list of localities with geographic coordinates is placed.

Limpet fauna of the Holarctic genus Acroloxus Beck, 1837 was examined in Lake Baikal. Morphology of protoconch and teleoconch of three species (A. baicalensis Kozhov, 1936, A. orientalis Kruglov et Starobogatov, 1991 and possible new Acroloxus species) was studied with SEM. Additional shell characters were described for A. baicalensis, collected from its type locality. Distribution of representatives of the genus Acroloxus in Lake Baikal and its basin was discussed.

The analysis of L. maximus allozymic variability on the Dnieper right-bank Ukraine territory testifies to the balanced proportion of homo- and heterozygotic genotypes in populations in most cases. Thus, this species is reproduced mostly amphimicticly. In some cases, probably, automixis takes place and leads to genotypes fixing in homozygotic state. This specis is characterized with stable chromosome numbers (n=31, 2n=62) and chromosome arms (NF=124). L. maximus morphometric parameters vary greatly but geographic tendencies this species morphological variability have not been found.
