a-b: coll. C. Vos ref TT482 In shallow water on sand. South China Sea, 71mm. Quite typical shape of the species, with the denticulate lip finished after the growth phase, and the canal twisted "like a string of cords". Spiral sculpture very typical. Please note the first and second primary cords, which give the shell its typical shape. In general, the coloration is very variable, as can be noticed in this specimen.
c-d: coll C. Vos ref. TT270, Taiwan, 50.8mm. Dwarf-like specimen with a large part of the periostracum preserved. Occasionally, some callus can occur on the columella, as can be seen in the apertural view, otherwise very typical specimen.
e: coll. C. Vos ref TT673, In shallow water, Taiwan, 60.3mm. The dorsal view illustrates the phased growth through the whitish line on the right (end of a previous growth phase after which the lip was dissolved), and the "breakline" left from the centre, which is a non-dissolved lip and the continuation of the shell growth following that phase.
