This paper summarizes the mechanisms behind the patterning of the intra-population spatial arrangement of the land snail Vallonia pulchella (Müller, 1774) in terms of edaphic and vegetation properties. The molluscs were collected from a regular grid in recultivated soil (the research station of Dnipro State Agrarian and Economic University, Pokrov, Ukraine). As predictors of the snail population abundance, spatial variables were used, as well as edaphic and vegetation indices. It is shown that V. pulchella to prefer microsites characterized by higher soil electrical conductivity, which contain larger aggregate fractions with low mechanical impedance and the low temperature at the depth of 0-10 cm, with a more developed dead plant layer, low-light and low hygromorph and heliomorph index values of the vegetation.

37 species of the land molluscs were identified in the material collected in 2002-2017,  many being earlier unknown from Zaporozhye region. In total 39 species of molluscs can be considered as reliably recorded from this region. The presence of some species is the result of anthropochory. This concerns first of all those land snails which have spread from the Crimea: Brephulopsis bidens, B. cylindrica, Phenacolimax annularis, Oxychilus deilus, Monacha fruticola, Xeropicta derbentina, X. krynickii, Eobania vermiculata, Helix lucorum. One species (Xerolenta obvia) was introduced to Zaporozhye region from the western part of Ukraine. The data obtained made it possible to clarify the current distribution of Helicopsis retowskii and Chondrula tridens martynovi over the territory of Ukraine.

A comparative analysis of the camera eyes of gastropod pulmonate molluscs Cepaea nemoralis and Cepaea hortensis was carried out on the basis of original and published data. It was demonstrated that the eyeballs and their main components in C. nemoralis and C. hortensis have more similarities in morphological and optical properties than in anatomical parameters.
