Conus mompichiensis (Olsson, 1964)

The shell is of medium size, solid, rather stout and broad, with a low spire with concave profile and about nine whorls, the apical ones corroded in the types. The early spire whorls are coronated, the later ones with a plain sharp shoulder. The body whorl is large, widest at the shoulder or just below it, the surface smooth or with hardly discernible spirals, even around the base. The surface above the shoulder, or on the subsutural fasciole, is relatively narrow, flat, or slightly concave, marked with five low spirals. The siphonal canal notch is hardly discernible. Faint color markings are shown on some specimens forming a pattern as shown in the figure (Plate 12, fig. 3a) of narrow solid ribbons or encircling bands.

Length 35.1 mm., greater diameter 20.4 mm. Holotype, USNM 644133; length 38.5 mm., greater diameter 21.7 mm. Paratype.
