Left: recently emptied shell in water; never dried. Periostracum as when live with raised spiral ridges. Protoconch always without periostracum. Patches where periostracum eroded show pinkish white shell beneath periostracum.
Right: same shell as on left 24 hours after being dried. Spiral ridges becoming obscure as periostracum shreds into bristle-like fragments.
