Eggs on snail shell?

[Idoc]

Does anyone know what these small round off-white bumps are on my Nerite Snail's shell could be? Eggs possibly? It seems like every other Nerite snail in the tank likes to take a ride on his/her shell... lol.

I received this snail from Reef Cleaners the other day and it was covered in these bumps. I thought I scraped them all off before I pour him in my Invert QT, but obviously I missed a few. Not sure if i should scrape again or let him be.

It looks like snail eggs, probably Nerite.
