Bullina nobilis from Izu Peninsula, Japan

Hello,
An attached picture is Bullina nobilis Habe, 1950. This is not B. lineata, I think, because of the pattern of lines differs. In B. nobilis the vertical lines hardly curve like B.lineata and the spiral sculpture is coarser.

I found it on sandy and when I touched it, it immediately tried to burrow into the sand. It was hard to take picture.

Dear Haruo,
Thanks for this photo. I agree that it looks like the shell described for Bullina nobilis. Unfortunately we still don't know anything about the anatomy of B. nobilis. Your photo, suggests that this species differs from B. lineata in the absence of any pigmentation in the animal.
Best wishes,
Bill Rudman
