Praticolella Pachyloma
''Praticolella'' is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae. This genus comprises about 15 species of small snails with semi-globose shells. Shell description The shells of these snails often have contrasting color bands, and are usually without apertural teeth, although a tooth may sometimes occur on the parietal wall of the aperture. Snails in this genus are distinguished from other polygyrid snails on the basis of their internal anatomy. Distribution Species of ''Praticolella'' may be found from Nicaragua and eastern Mexico, into the southeastern United States, from Texas to North Carolina.Pilsbry, Henry A. 1940. ''Land Mollusca of North America (North of Mexico)''. Acad. Nat. Sci. Philadelphia, Monograph 3, vol. 1(2): 688-702. Species This genus includes the following species and subspecies:Sandoval, A.

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...
