(Figs 121–124)

1893 Conus (Chelyconus) mucronatolaevis – SACCO, p. 66, pl. 6, fig. 26, varieties: fusoelegans, longo-

vuloides, laevispira, taurobiconica, glandispira, globospira, permamillata, conicangulata: p.

66–67, pl. 6, figs 27–34. 1964 Conus mucronatolaevis Sacco – HALL, p. 149, pl. 26, figs 9–11, 14, 20 (cum syn.). 1984 Chelyconus mucronatolaevis Sacco – FERRERO MORTARA et al., p. 116, pl. 18, fig. 8. 1999 Conus (Chelyconus) mucronatolaevis (Sacco) – MUÑIZ, p. 53, figs 2/L, 7/M–N (cum syn.).

Material – 34 specimens.

Description – Shell medium-sized (SL: 25–43). Spire of moderate height, outline convex, apex projected. Spiral whorls smooth or finely striate. Shoulder rounded. Body whorl ventricosely conical, outline straight, smooth with fine ridges at the base. Subsutural flexure asymmetrically curved.

Remarks – Like SACCO’s material (1893, pl. 6, figs 27–34), the Letkés specimens also show moderate variety of development of the spire. The taxon is allied to Plagioconus marii , but it differs in lower and wider spire.

Distribution – Italy (LM-MM), Bulgaria, (?) Romania (MM), Tunisia (UM-LP), Spain (LP). Hungary: Letkés (MM).
