THE SMALL GREY SLUG, (Limax cinereus,)
Resembles a Snail in all points except that it has no shell, consequently the brown skin of the back is rougher and stronger than that of the Snail. Its progress on the ground may easily be traced by the slime which it leaves in its track. Few animals are more destructive to vegetation than these.
THE BLACK SLUG, (Arion ater,)
Is a well-known inhabitant of our fields and meadows, during the summer season. The country people consider its appearance as an indication of approaching rain; but this is rather to be accounted for by the moisture of the ground and plants. Indeed, it very seldom appears abroad during dry weather. The Black Slug feeds on the leaves of different kinds of plants.
THE SEPIA, OR CUTTLE-FISH. (Sepia officinalis.)
