  1. Specimens were selected to cover the variation observed in populations. If the actual trait is on the border between two values (coded differently by the independent examiners), both values are indicated. Material indicated with a 1in the population code column was not bleached and reveals the actual appearance in the field; 2reflects assessments by Genner et al. [21].
  2. Character explanation:
  3. IN = intensity of the shell background color: (1) very pale, (2) pale, (3) medium, (4) dark.
  4. TI = background tint of the shell: (1) yellow to brown, (2) greenish, (3) orange to reddish, (4) white, (5) brown to black.
  5. HE = heterogeneity of the background color among different parts of a shell whorl: (0) homogeneous, (1) a distinctly darker band below the suture.
  6. DO = overall density of reddish-brown color patterning on the whole shell, except the zone just below the sutures: (0) no patterning, (1) medium, (2) dense.
  7. SP = type of patterning, expressed as the proportion of spots vs. flames: (0) only flames, (1) more flames than spots, (2) more spots than flames, (3) only spots.
  8. SO = size of the individual spots/flames: (1) small spots/narrow flames, (2) medium, (3) large spots/wide flames.
  9. HO = heterogeneity of color patterning among different parts of the whorl: (1) homogeneous, (2) slightly different patterns just below the sutures (i.e. in the subsutural zone), (3) strongly different patterns in the subsutural zone compared to those on the rest of the shell.
  10. SH = presence and sharpness of a dark band on the axial edge of the aperture (columellar band) and along the base of the body whorl: (1) absent, (2) diffuse, (3) sharp.
  11. SC = size of the dark band, when present: (1) narrow, (2) medium, (3) wide.
  12. CO = conicity of the shell: (1) acute, (2) medium, (3) blunted cone.
  13. RO = roundness of the body whorl: (1) flat, (2) slightly rounded, (3) well-rounded.
  14. GR = spiral cords/grooves: (0) absent, (1) shallow grooves/weakly pronounced cords, (2) intermediate, (3) very deep grooves/strongly pronounced cords.
  15. CD = subsutural spiral cord: (0) similar to the other spiral cords, (1) pronounced/swollen, but smooth, (2) pronounced/swollen with nods, (3) similar to other spiral cords but with large nods.
  16. RI = density and width of axial ribs: (0) none, (1) a few narrow ribs, (2) a few large ribs, (3) many narrow ribs.
  17. RD = depth of axial ribs when present: (1) shallow, (2) medium, (3) deep.
  18. ‘na’ indicates when the trait is not applicable.
