Several species of freshwater snails are for the first time registered from the waterbodies of the central part European Russia (Moscow Region and adjacent areas) based upon own author’s samplings and museum collections. These are: Lymnaea (Corvusiana) corvus (Gmelin, 1791), Lymnaea (Corvusiana) gueretiniana (Servain, 1881), L. (S.) archangelica Kruglov et Starobogatov, 1986, L. (S.) fusca (C. Pfeiffer, 1821) sensu Kruglov, 2005, L. (S.) callomphala (Servain, 1881), L. (Peregriana) fulva (Küster, 1862), Anisus (Costorbis) strauchianus (Clessin, 1886), Physa taslei Bourguignat, 1862, and Pseudosphaerium pseudosphaerium (Favre, 1927). The data on their ecology and distribution in the region are given alongside with diagnostic characters, taxonomic and nomenclatorial remarks. This newly obtained information is useful for more exact zoogeographical characterization of the region. It has been shown that the malacofauna of the upper Volgian drainage basin is, possibly, not so zoogeographically peculiar as it was considered earlier.

Lymnaea (Stagnicola) likharevi Lazareva, 1967 and Lymnaea (Stagnicola) saridalensis Mozley, 1934 – two closely allied lymnaeid species that inhabit Western Siberia and, in many cases, may co-occur in the same habitat. A detailed study of conchological and anatomical variation of the two species from seven syntopic samples has shown that these are non-diagnosable since there is no morphological hiatus to separate them. A new synonymy is established: L. likharevi is a junior synonym of L. saridalensis. The data on the type series of the studied species as well of Lymnaea draveri Mozley, 1934 are provided.

The present investigation was undertaken to study a shell disease of the freshwater snail, Pila globosa. Observations were made in June-July in four consecutive years. The disease first appears as blisters in the periostracum and then, once the periostracum is lost from these lesions, dissolution of the underlying calcified layer. The numerically predominant bacterial genera in the lesions included Aeromonas, Pseudomonas, Escherichia and Listeria. Communication describes this previously unreported shell disease, which may be a health problem in apple snails.

It is established that all reports of Oxychilus diaphanellus outside of Crimea were based on an erroneous identification of Oxychilus translucidus. The differences between these two species, as well as those between O. translucidus and some other species of Oxychilinae in Ukraine, are discussed.

The data on distribution of molluscs of the genus Digyrcidum Locard, 1882 in waterbodies of the Urals and Western Siberia are given. A new species, Digyrcidum starobogatovi Andreeva et Lazutkina, sp. nov., is described. This species inhabits waterbodies of the Urals and Western Siberia cojointly with the species Digyrcidum bouguirgnati (Paladilhe, 1869).

The patterns of the migration activity of 43 species of land snails and slugs were analyzed on the basis of both original and literature data. Different species of terrestrial mollusks demonstrate significant intra- and interspecific differences in their migratory abilities. During short-term experiments, the distance from release point was determined mainly by displacement of individuals by random (Brownian) motion. Random events of passive dispersal of the snails (homing) were observed in the course of the long-term experiments lasting several years. The possibility of passive dispersal of terrestrial mollusks by means of different mechanisms (anemochory, hydrochory, zoochory and anthropochory) has been shown. Two distinct spatial scales in the process of the terrestrial mollusks invasion (transcontinental and intra-continental) were distinguished. Most cases of transcontinental invasion represent mainly the transfer of European species to Africa, North and South America, and Australia.
