Material – 66 specimens.

Description – Shell large (SL: 22–62). Spire of low to moderate height, outline straight to slightly concave. Spiral whorls smooth, sutural ramps flat to gently concave. Shoulder angulate. Body whorl conical, slightly elongate, outline convex, smooth with fine ridges at the base. Subsutural flexure asymmetrically curved, of moderate depth.

Remarks – The species shows moderate variety of development of the spire. Some Letkés specimens are close to the type of M. mercati miocaenicus ( HÖRNES 1856, pl. 2, fig. 1), others resemble some Italian forms ( SACCO 1893, pl. 2, figs 1, 3, 5, 7–8, 10, 13).
