FIG. 4. — Vitrinid species occurring in syntopy with Hessemilimax kotulae (Westerlund, 1883) in the High Vosges and apex of the shells: A, Eucobresia diaphana (Draparnaud, 1805) (extended body length: 14.6 mm), specimen sampled at locality no. 01; B, Phenacolimax major (A. Férussac, 1807) (extended body length: 9.6 mm), specimen sampled at locality no. 04; C, Vitrina pellucida (O. F. Müller, 1774) (extended body length: 9.3 mm), specimen sampled at locality no. 03; D, apex of the shell of H. kotulae (animal figured in Fig. 2I); E, apex of the shell of E. diaphana with spiral rows of small pits (animal figured in Fig. 4A); F, apex of the shell of P. major with spiral rows of small pits (animal figured in Fig. 4B); G, apex of the shell of V. pellucida with spiral rows of small pits (animal figured in Fig. 4C). Scale bar: 500 µm. In A to C, the white arrows indicate the folding of the mantle onto the shell. In E, F and G the arrows indicate the spirals of small pits.
