Rochia conus, common name the cone top shell, is a species of sea snail, a marine gastropod mollusk in the family Tegulidae.

The 10 whorls are spirally encircled by numerous (about 10 on upper surface) beaded lirae, which are separated by superficial interstices.

Above the sutures there is a series of short folds or knobs which usually become obsolescent upon the periphery of the body whorl.

The columella is nearly vertically descending, subdentate at base, above with a profoundly entering spiral fold.

[3] This marine species occurs in the Red Sea, off the Philippines, Indo-Mamaysia, off Vietnam, New Caledonia and New South Wales, Australia.
