Opis:: A specimen of Trochulus hispidus from Buchenbach, Germany, had its male and female parts of thereproductive system completely separated. The female part lacked auxiliary organs. The male part opened into the genital atrium, but the vas deferens was blind-ended in a way precluding sperm transfer.

Opis:: The diploid chromosome set of Arion vulgaris Moquin-Tandon consists of 52 chromosomes, with the karyotype formula: 2n = 44m+6sm+2st=52; FN = 104. The chromosome number (n = 26, 2n = 52) of A. vulgaris is identical to that of A. subfuscus sensu lato, A. ater (L.) and A. rufus (L.) which may suggest their close relationship.

natural condition
Opis:: Growth of Chilostoma faustinum (Rossmässler, 1835) was recorded under natural conditions in Romincka Forest (NE. Poland), one of the northernmost localities of the species. During the growing season (April–October) the average growth rate was 0.22 whorl/month. In the local conditions Ch. faustinum Leeds three growing seasons to complete its shell growth. Shells of Ch. faustinum from Romincka Forest are slightly smaller than in the other studied populations: their average width is 16.5 mm (range 13–19 mm); and the average number of whorls is 4.5 (range 4–5).

uniparental reproduction
Opis:: Balea fallax (Rossm.) collected from the Roztocze Upland (SE. Poland) was kept in the laboratory for four years. Observations were conducted between March and October when the snails were kept at room temperature (18-25°C); in winter they were stored at 3°C. The egg-laying period started in late March and lasted till October, with maxima in spring and early autumn. The snails laid oval, gelatinous eggs with separatecalcium carbonate crystals in the external envelope (average egg size 1.96 × 1.73 mm). The eggs were deposited in batches (up to 14 eggs at a time) or singly. The number of batches per snail per year ranged between 1and 4. Snails isolated before maturation laid defective eggs which failed to develop, which suggest that the speciesis incapable of uniparental reproduction or at least the ability is very limited. The reproduction rate decreased during consecutive years, probably as a result of the aging or the shortage of allosperm in isolated individuals.Compared to batches of typically oviparous clausiliids, eggs of B. fallax hatched slightly earlier (interval between oviposition and hatching lasted 8-10 days at room temperature). It is likely that the adults retained developing eggs in the uterus for a short time. The juveniles needed at least 6 months to attain the ultimates hell size.
