Animal of M<:soii jxtlliotn. — [B. & B.] Fig. ^--" Animal, very similar to the LimacidcE; except the posterior part of the body, which is spiral, and raised off the foot, to be inserted in the shell; the pulmonary orifice is in the collar, or margin, of the mantle, near the angle of the mouth of the shell; the anal opening is contiguous thereto. Slicll discoidal, sub-orbicular, turbinate, or trochiform. Obs. — The true snails are oviparous, and hermaphro- dite ; but require the union of two individuals, for reciprocal fecundation. They are both herbivorous and carnivorous. The eggs are usually deposited in places which they inhabit, to the number of fifty, or more. According to Dr. Binney, the depth is regulated by the distance the animal can penetrate the earth, while its shell remains above ground. They are globular, or roundly oval, sometimes slightly connected in Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Hartman, William Dell, 1817-1899; Michener, Ezra, 1794-1887.
