Vespericola Oria
''Vespericola'' is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae. Habitat These snails are found along the Pacific Coast of North America, from southern Alaska and British Columbia to California. Shell description The shells of these small to medium, globose or depressed globose snails are usually some shade of brown, sometimes without apertural teeth and sometimes with a single tooth on the parietal wall. Small periostracal hairs may be observed on the shell surface of many specimens, but the shells otherwise resemble those of ''Praticolella'' or ''Mesodon''.Pilsbry, Henry A. 1940. ''Land Mollusca of North America (North of Mexico)''. Acad. Nat. Sci. Philadelphia, Monograph 3, vol. 1(2): 892-912. Anatomy According to Pilsbry (1940), ''Vespericola'' "differs from all other Polygyridae by the possession of a well-developed though rather short verge, and by the peculiar shape of the epiphallus".

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 ...
