_Limax agrestis_ has been seen devouring the crushed remains of _Arion ater_. Five specimens of the same species were once noticed busily devouring a May-fly each, and this in the middle of a large meadow, where it may be presumed there was no lack of green food. The capture and eating of insects by Mollusca seems very remarkable, but this story does not stand alone. Mr. T. Vernon Wollaston once enclosed in a bottle at least three dozen specimens of Coleoptera together with 4 _Helix cantiana_, 5 _H. hispida_, and 1 _H. virgata_, together with an abundant supply of fresh leaves and grass. About a fortnight afterwards, on the bottle being opened, it was found that every single specimen of the Coleoptera had been devoured by the snails.[52] _Amalia marginata_ in captivity has been fed upon the larvae of _Euchelia jacobaeae_, eating three in two hours.[53] _Limax maximus_ (Fig. 19) has been seen frequently to make its way into a dairy and feed on raw beef.[54] Individuals kept in confinement are guilty of cannibalism. Mr. W. A. Gain kept three specimens in a box together, and found one of them two-thirds eaten, “the tail left clean cut off, reminding one of that portion of a fish on a fishmonger’s stall.” That starvation did not prompt the crime was proved by the fact that during the preceding night the slug had been supplied with, and had eaten, a considerable quantity of its favourite food. On two other occasions the same observer found one of his slugs deprived of its slime and a portion of its skin, and in a dying condition.[55] An adult _L. maximus_, kept for thirty-three days in captivity with a young _Arion ater_, attacked it frequently, denuded it of its slime, and gnawed numerous small pieces of skin off the body and mantle.[56] The present writer has found no better bait for this species on a warm summer night than the bodies of its brethren which were slain on the night preceding; it will also devour dead _Helix aspersa_. Mr. Gain considers it a very dainty feeder, preferring fungi to all other foods, and apparently doing no harm in the garden. [Illustration: FIG. 19.--_Limax maximus_ L. =PO=, pulmonary orifice: × ⅔.] _Limax flavus_, which is fond of inhabiting the vicinity of cellars, makes its presence most disagreeable by attacking articles of food, and especially by insinuating itself into vessels containing meal and flour.[57] It is particularly partial to cream.
