Material – 147 specimens.

Description – Shell medium-sized (SL: 19–43). Spire of low to moderate height, outline slightly convex. Spiral whorls smooth. Shoulder rounded to subangulate. Body whorl conical, outline straight to slightly convex, smooth with pronounced growth lines, and with fine grooves at the base. Subsutural flexure asymmetrically curved.

Remarks – The intraspecific varieties of the species were studied by DAVOLI (1972). Some of the Letkés specimens are close to the syntype (figured by FERRERO MORTARA et al. 1984, pl. 18, fig. 10), others differ in subangulate shoulder. V. ponderosus is a closely allied form, however, it differs in higher spire.

Distribution – Italy (M-P), (?) Austria, Turkey (MM), Spain (LP). Hungary: Letkés, Szob, Budapest: Illés street (MM).
