Deb, the snail in question is a Lancetooth Snail. They are actually predatory and prey upon other snails and slugs. It would be interesting to watch one of those guys stalk another snail wouldnt it?! (bring a lawnchair) ;D
Those are sure interesting snails!! Ive seen similar aquatic ones and in the garden there were very tiny versions with the same shell shape but black, glossy shells. I have not seen terrestrial snails like those though. Are there creatures still living inside when you find them?

Deb, meant to say if you've also found live ones. Knew you guys would never take one out of its habitat but I was not clear. A thought I had which is probably wrong was an aquatic snail whose pond or puddle dried up and thus the empty shells.
A name that Ive run across for snails is Robert G. Forsyth who seems to be an expert on them. I came across a way to contact him by following the link. An email link is provided near the bottom.
