Varioconus olivaeformis ( Hoernes et Auinger, 1879)

(Figs 125–130)

1879 Conus (Chelyconus) olivaeformis nov. form. – HOERNES & AUINGER, p. 52, pl. 1, fig. 23.

1973 Conus (Chelyconus) olivaeformis Hoernes et Auinger – BOHN-HAVAS, p. 1122, pl. 7, figs 5–6.

Material – 244 specimens.

Description – Shell moderately small (SL: 11–25). Spire moderate to high, outline straight to slightly convex. Teleoconch sutural ramps slightly convex, smooth. Shoulder rounded. Body whorl slightly elongate, narrowly ovate, outline convex, smooth with 4 spiral grooves at the base. Aperture wider at the base than at the shoulder. Anterior notch slightly developed. Subsutural flexure asymmetrically curved.

Remarks – Some of the Letkés specimens correspond to the type, others with slightly lower spire are close to that figured by BOHN-HAVAS (1973). V. olivaeformis was considered as one of the synonyms of V. ponderosus by HALL (1964); however, the species differs in smaller size, and in narrower shell.

Distribution – (?) Czech Republic, Romania (MM), (?) Italy (UM). Hungary:

Letkés, Pécsszabolcs (MM).
