Ventridens arcellus Hubricht, 1976

Family: Gastrodontidae
Common name: Golden Dome

Width: 12.9–13.1 mm
Height: 9.2–11.1 mm
Whorls: 6.5+

Ventridens arcellus has a shiny, cone-shaped shell like several others in its family.  There are no teeth in the aperture. The shell is greenish yellow to golden, and the umbilicus is deep and well-like, but not as narrow as in V. ligera. Behind the aperture on the underside of the shell there is often has a light, opaque spot that suggests and internal callus. It is smaller, less green, more yellow, and has a higher spire at the apex and a deeper excavation around the umbilicus than V. acerra. Radial striae appear on the outer whorls, and though the base is much smoother, faint, spiral striae can be found there as well. 

This species is somewhat uncommon, but when found it is in mountains at elevations above 3,000 feet, usually in leaf litter (Hubricht, 1985).  

A synonym for V. arcellus is Zonitoides (Ventricallus) arcellus.

The range of this species is higher elevations of the southern Appalachian Mountains, from western Maryland to northern Alabama (Hubricht, 1985). It is found only in a few counties of western Virginia.
