This is an ovulid snail, Calpurnus verrucosus. Although not a slug, I have a page for the Ovulidae, because when they have their often colourful mantle extended out over the shell, they can be easily mistaken for slugs. In this species, the black spotted folds of the mantle almost completely enclose the white shell.
In fact ovulids seem to have evolved the ability to store noxious chemicals from their food, in their bodies. Like many nudibranchs, which do the same thing, these chemicals can then be used as part of the snail's defensive strategy.
