Chondrina massotiana ( Bourguignat, 1863)

Notes.— Pupa massotiana was considered one of many synonyms of C. farinesii by Gittenberger (1973). Since it has to be accepted that the latter species is far less variable conchologically than assumed, several nominal taxa have to rise from synonymy. In C. massotiana the shell is slender to very slender conical, with growthlines that may be partially arranged as fine riblets. Apertural teeth variable across its range, but nearly always with at least a rather prominent columellaris and a parietalis; never with more that two palatal folds and always without a spiralis. By its more slender shell with a columellaris and a parietalis, C. massotiana can be distinguished from C. farinesii . Two geographical forms, that are considered subspecies here, can be recognized more or less clearly.
