New Species - Green Cellar Slug

I turned over a large rock and found these two large slugs underneath. I think they are Green Cellar Slugs (Limacus maculatus) which is a fairly common slug to find here apparently. The blue tentacles distinguish it from the Leopard Slug and lack of a yellow line on the tail from the Yellow Cellar Slug. They like Lichen so that would be a good location for them near an old Moss and Lichen covered wall.
