Nerite snail vs other snails

[jennandjuicetm]

How can I tell the difference? I bought 4 Nerites today and when I got home realized 2 were Olive and 2 were black. Is the black one a nerite?

They both look like they are Nerite snails, most of the time snail IDing comes down the the shell. Are there shells the same, if they are then there is a good chance that the snails of both colors are the same.

Yup they are shaped the same. Thans!
