The snails and their allies, constituting the family Heli- €iNMy are closely allied to the slugs in organization; differing in but little else than the possession of a shell into which the body may be withdrawn. The common garden snail of this country, and the helix pomatia, or edible snail of France and Italy, are well-known examples of this family. More striking ones are to be found, however, in tropical climates, where some species of the genus Bulimus attain to great size, the eggs being as large as a pigeon's. In some species, the direction of the coils of the shell is opposite to what it is in other spiral shells; such are said to be reversed. A European species of this genus is one most remarkable for the decollation of its shell. An. Achatina Zebra. Achatma Virginea. other large snail of tropical climates is the achatina, which feeds on trees and shrubs, chiefly on the western coast of Africa and 820. Describe the second family. 821.
