Henry Augustus Pilsbry created what was then the subgenus "Appalachina" (under the genus "Mesodon"), a group of land snails in the family Polygyridae, for those snails with comparatively depressed (flat) shells and an open umbilicus (the center of the underside of the shell). The reproductive anatomy of these snails is important for distinguishing them from other polygyridsPilsbry, Henry A. (1940). Land Mollusca of North America (North of Mexico). Acad. Nat. Sci.
