Slugs will sometimes bite their captor’s hands. Mr. Kew relates that a _Limax agrestis_, on being stopped with the finger, while endeavouring to escape from the attack of a large _Arion_, attempted to bite fiercely, the rasping action of its radula being plainly felt. According to the same authority, probably all the slugs will rasp the skin of the finger, if it is held out to them, and continue to do so for a considerable time, without however actually drawing blood.[58] While Mr. Gain was handling a large _Arion ater_, it at once seized one of the folds of skin between the fingers of the hand on which it was placed; after the action of the radula had been allowed to continue for about a minute, the skin was seen to be abraded.[59] Another specimen of _Arion ater_, carried in the hand for a long time enclosed in a dock leaf, began to rasp the skin. The operation was permitted until it became too painful to bear. Examination with a lens showed the skin almost rasped away, and the place remained tender and sore, like a slight burn, for several days.[60] _Helix pisana_, if freshly caught, and placed in a box with other species, will set to work and devour them within twenty-four hours. The present writer has noticed it, in this position, attack and kill large specimens of _H. ericetorum_, cleaning them completely out, and inserting its elongated body into the top whorls of its unfortunate victims in a most remarkable manner. Amongst a large number of species bred in captivity by Miss F. M. Hele,[61] was _Hyalinia Draparnaldi_. In the first summer the young offspring were fed on cabbage, coltsfoot, and broadleafed docks. They would not hibernate even in the severest frosts, and, no outdoor food being available, were fed on chopped beef. This, Miss Hele thinks, must have degenerated their appetites, for in the following spring and summer they constantly devoured each other. _Zonites algirus_ feeds on decayed fruit and vegetables, and on stinking flesh.[62] _Achatina panthera_ has been known to eat meat, other snails (when dead), vegetables, and paper.[63] The common _Stenogyra decollata_ of the South of Europe has a very bad character for flesh-eating habits, when kept in captivity. Mr. Binney[64] kept a number for a long time as scavengers, to clean the shells of other snails. As soon as a living _Helix_ was placed in a box with them, one would attack it, introduce itself into the upper whorls, and completely remove the animal. One day a number of _Succinea ovalis_ were left with them for a short time, and disappeared entirely! The _Stenogyra_ had eaten shell as well as animal. This view of _Stenogyra_ is quite confirmed by Miss Hele, who has bred them in thousands. “I can keep,” she writes,[65] “no small _Helix_ or _Bulimus_ with them, for they at once kill and eat them. They will also eat raw meat.”
