This paper reports the systematics of the Clausiliidae species occurring in Son La Province, Vietnam. Specimens of 15 species and subspecies of Clausiliidae from Son La were investigated based on their shell characteristics. The subspecies Garnieria mouhoti nhuongi subsp. nov. was collected in Phu Yen, Muong Do, approximately 200 km NE of the type locality of the nominotypical subspecies Garnieria mouhoti mouhoti. This is the first species of genus Garnieria Bourguignat, 1877 from Vietnam.

The results of investigation demonstrate that the eye of Succinea putris is adapted for vision in daytime under pretty high level of illumination.

The study of reproductive tract of the south-east Asian species Helix pernobilis Férussac, 1821 has shown that the species belongs to the genus Koratia Godwin-Austen 1919. The problem of taxonomic rank of the genus Koratia and its comparison with related taxa (Ariophanta and Hemiplecta) are briefly discussed.

Pisidium nevillianum Theobald, 1876, a common pea clam species that widely ranged from India to Indochina, was recorded in the Indawgyi Lake, Northern Myanmar for the first time. These specimens share the same or very similar 16S rRNA haplotypes as specimens from Nepal (geographic distance of over 1,400 km), which could reveal a high dispersal rate of the species, likely via water birds. Same high dispersal possibilities were observed for many other sphaeriid species.

The article deals with the fauna of aquatic snails (Gastropoda) of the Nature Reserve (Zapovednik) “Malaya Sos’va” (Russia, Western Siberia, Tyumen Region). It is the first review of the zapovednik malacofauna ever published. 44 waterbodies of different types were samples in August of 2014, 16 species of Gastropoda belonging to four families has been registered. The annotated check-list of species along with brief zoogeographic characteristics of the fauna are provided. The fauna of aquatic snails of the “Malaya Sos’va” is impowerished as compared to other regions of Western Siberia. The possible factors caused this low taxonomic richness are discussed.

The family Streptaxidae comprise 8 species and subspecies occurring in Son La, North-western Vietnam. The present paper provides data relevant to these species and the descriptions of two new species. Stemmatopsis nangphaiensis sp. nov. has an oblique-heliciform shell with elevated spire. The aperture is quadrangular with rounded angles, toothless, peristome is thick and slightly expanded. Stemmatopsis vanhoensis sp. nov. has a depressed-heliciform shell. The umbilicus is wide with long curvy furrow. The aperture is quadrangular and toothless, peristome is very thick and expanded.

Data on archaeomalacological samples from Nikolaevskoe I (Primorye), a medieval settlement of Bohai (Parhae) Empire period (VIII–X centuries) located in the Chuka and Ilistaya rivers valley, Khanka Lake water basin, and their interpretations, are presented. In total, 8 species of molluscs were found, including three freshwater (2 bivalves and 1 gastropod species) and five marine (4 bivalves and 1 gastropod) species. The majority of shell fragments collected in archaeological deposits belongs to the freshwater pearl mussels Dahurinaia dahurica (Middendorff, 1850). Among marine mollusks, bivalves Anadarainaequivalvis” (Bruguière, 1789) and Glycymeris yessoensis (Sowerby III, 1889) are predominant. Descriptions of shell peculiarities as related to human use are given. A comparison of valve teeth of modern and excavated fresh-water bivalves shows their identity. Ways of utilizations of mollusks by Bohai people are discussed. Shells from Bohai archaeological deposits in Primorye are illustrated for the first time in details.

The findings of living specimens of two gadilid scaphopods – Cadulus subfusiformis (M. Sars, 1865) and Pulsellum lofotense (M. Sars, 186) in the coastal waters of Kola Peninsula (SW Barents Sea) are described. Cadulus subfusiformis was previously known from the region only by single empty shell, Pulsellum lofotense was recorded previously without exact locality and was not listed in the modern literature dedicated to the Russian fauna.

Additional specimens of Papyriscala tricincta were collected for the first time since original description of the species. Comparison of the shells with several similar Indo-Pacific species allowed us to conclude that P. tricincta is a junior subjective synonym of the broadly distributed Epitonium clementinum.
