Cantareus species (?) Fig. 9

Helix aspersa : Kobelt 1888, Iconographie (2) 3: 9-10, pl. 69, figs 359 & 360 [non Helix aspersa O. F. Müller, 1774 [Gorges d’Isser bei Palestro].

Helix (Cryptomphalus) aspersa : Sacchi 1955, Italian Journal of Zoology 22(2): 638, pl. 3, fig. E [Palaestro].

This specimen was collected by Kobelt in the Gorge d’Isser; it lacks the malleation typical for Cornu aspersum , and thus is here considered to rather constitute a species in Cantareus than in Cornu . However, it also lacks the riblets on the teleoconch, but also has the typical granulation on the whorl exactly like in the specimens from the Djudjura Mts. This form might represent another species close to C. subapertus , but preserved specimens from the canyon are needed to decide about its status. This form might be a separate species endemic to the Gorge d’Isser.
