[2] Many specimens of Clanculus tonnerrei (G & H Nevill 1874) have been misidentified as belonging to Euchelus bicinctus, following a misidentification of Issel (1869) (Herbert, 1996).

The smaller ones are interpolated, numbering 5 to 6 between suture and the periphery, 7 to 8 on the base of the body whorl obtusely angulated.

The columella is disjoined and prominently denticulate above, oblique, with 1 or 2 tubercles where it joins the basal margin.

Between this and the peripheral carina there are 4, of equal breadth to the elevated interspaces; and on the base about 12.

[4] This species occurs in the Red Sea and in the Indian Ocean off Djibouti, the Mascarene basin, Kenya, Mozambique and Tanzania.
