The shell is thin, glossy, and dark olive-green, with very sparse black axial streaks. The umbilicus is much wider than in typical Powelliphanta rossiana.
[edit] Conservation status
Powelliphanta rossiana "Fox" does not appear to be under immediate predator threat. Habitat loss and other human activity, such as the building of communication towers, are potential threats.
Major diameter is up to 39 mm, and height 21 mm.
Powelliphanta rossiana "Fox" is classified by the New Zealand Department of Conservation as Range Restricted.
