Bulimus, a genus of land snails of the family helicidm, largest and most numerous in the humid regions of northern Brazil. The shell is oblong or turreted, with the longitudinal margins unequal, with or without a tooth. The B. rosaceus is generally found in the dry season adhering to the under surface of stones near the seashore, or to the leaves of a plant resembling the aloe, for which it has an unexplained preference. In the wet season it burrows near the roots of this plant, and deposits its eggs about two inches below the surface of the ground. During the whole dry season it appears to be in a dormant state. The B. ovatus attains a length of six inches, and is exposed for sale in the markets of Rio de Janeiro; like other tropical species, it cements dead leaves together to conceal and protect its large, brittle, and bird-like eggs, which are an inch long. At least 30 fossil species are found in the eocene. The species of temperate regions are of small size.
