Recent Calliostoma

[Coco]

By showing Sara my current shells, I realized that I have a different Calliostoma in my box of C. zizyphinum. It was found in the Côtes d'Armor in northern France.

 

Its difference lies in the fact that some turns are more marked than on the C. zizyphinum. What do you think about that ? @MikeR?

Thanks.

Unfortunately, the recent European molluscan fauna is outside of my area of expertise.
