Besides Helix pomatia, according to Moquin-Tandon, they eat in the north of France Helix sylvatica and H. nemoralis; at Montpelier, as we have already said, H. aspersa and H. rhodostoma; at Avignon, also, these, along with H. vermicula, are favourites. In Provence, Helix Pisana, with H. aspersa and melastoma, are preferred. At Bonifacio, Helix aspersa, H. vermicula, and, more rarely, H. rhodostoma; and in other localities the smaller species and young individuals of the larger kinds are employed for feeding poultry.

Certain species are also employed for feeding ducks. Thus, in the neighbourhood of Montpelier, ducks are fed upon Helix variabilis and H. rhodostoma. Some fishes, especially the young salmon, are very partial to the flesh of snails.

This very important genera is very numerous in species, which are distributed in groups according to the form of the shell; that is, whether it be globulous, as in Fig. 197, tun-bottomed, as in Fig. 198, plain or biform, as in Fig. 199, or truncated, as in Figs. 200 and 201. These figures will give the reader some idea of the multiplied and elegant forms which the shells of Helix sometimes assume.
