Cub Scout Shell Project

[wdland]

Hi.  I hope someone can help me.  I am a cub scout den mom.  We are working on a project next week involving shells.  I bought the boys these shells from the craft store, but I am having trouble identifying them.  I have tried doing it myself, but I am overwhelmed.  I never really thought about how many shells there are in the world until I tried to identify them!  And, to my untrained eyes,
many look similar to each other.  I hope someone can help me out. 
Thank you.
Danielle
