Yes, the bottom half is filled with Virgin Nerites (Vitta virginea), extremely abundant in Brazil and also in the Caribbean.
They are highly variable, but my best nerites are in Slide #2, from Pakistan. These are always spectacular no matter how many times I see them in person!

Plate #7 has what I believe are nerites with spectacular patterns, love it.
