Tetradium

My largest Westerna gigantea. Part of the shell is preserved, which is smooth and have no ridges. Compare to Turbonopsis and Floydia its more tightly coiled and lacks the ridges when shell are preserved. Uncommon - I suspect its more due to overharvested as I tend to find more juveniles than adults.
