Roman Snails

As children we used go on the Downs to collect Rose Hips for making syrup;but our parents had a contact who used to have a liking for (what we called) Roman Snails, and we collected them for him.   I think we received a couple of Bob for a bag full.  I haven't seen one for a long time, until today when, on a walk along the Downs, we encountered several. 

And here is one of them, they are bigger than your average garden snail, but quite what they taste like I have no idea, and I am not rushing to find out.
