For morphological and molecular characterisation of this species, see Schniebs et al. (2013) and Vinarski et al. (2016). P. peregra inhabits Europe (except of the northern part), the Urals and the southwest part of Western Siberia ( Glöer 2002, 2019; Khokhutkin et al. 2009; Andreeva et al. 2010; Schniebs et al. 2013; Vinarski et al. 2016). In many recent publications, this species has been referred to as Radix labiata ( Rossmässler, 1835).

Nomenclatorial note.

Falkner et al. (2002) argued that the lymnaeid species, which had been commonly named Radix (or Lymnaea ) peregra by the European authors, does not occur in Denmark, the type country of Müller’s Buccinum peregrum . These authors treated B. peregrum as a junior synonym of Helix balthica Linnaeus, 1758 and proposed the name Radix labiata for designation of R. peregra auct. Such authors as Glöer (2002, 2019) and Welter-Schultes (2012) followed it, but Vinarski (2017) doubted this decision. According to him, Falkner et al. (2002) did not present the total evidence for the absence of R. peregra auct. from Denmark and their assumption still needs strong confirmation. The type specimens of Limnaeus pereger var. labiatus (kept in NHMW) were considered by Vinarski (2017) as juvenile individuals of R. balthica . Therefore, it was unnecessary to replace a well-established taxonomic name R. peregra with a long-forgotten one, R. labiata .
