Oxychilus navarricus, before 2002 known as Oxychilus helveticus (Blum, 1881), is a species of small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Oxychilidae, the glass snails.
For terms see gastropod shell.
The 4.5–6 by 7–13 mm (0.18–0.24 by 0.28–0.51 in) shell is thin and a light horny yellowish colour. It is whitish near the umbilicus and very shiny, almost smooth. The outline is almost globulous. There are 4.5-6 weakly convex whorls with weak suture. The last whorl width is 1.5x or less of the preceding whorl which is well rounded at lower side. The umbilicus is not very wide, 1/8–1/7 of diameter. Genitalia: internal ornamentation of proximal penis consisting of more than seven longitudinal pleats, sometimes straight and distinct, sometimes wavy, slender and connected by lateral projections giving a reticulate appearance.

This species is known to occur in a number of countries and islands including:
The umbilicus of a shell is the axially aligned, hollow cone-shaped space within the whorls of a coiled mollusc shell. The term umbilicus is often used in descriptions of gastropod shells, i.e. it is a feature present on the ventral side of many snail shells, including some species of sea snails, land snails, and freshwater snails.
The gastropod shell is part of the body of many gastropods, including snails, 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, 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.
