Garrett's original text (the type description) reads as follows:
Shell subdiscoid, openly umbilicate, thin, subpellucid, cinereous, under a brownish horn-colored epidermis, adults decorticated, rarely with radiating dashes of reddish brown, arcuately ribbed, ribs lamellar, regular, rather closely set, continued on the base, interstices very finely striated; spire flatly convex; suture channeled; whorls 5, convex, slowly increasing, last one convexly declivous above, rounded beneath, obsoletely angular on the periphery; umbilicus deep, exposing the whorls, about a fourth the diameter of the shell; aperture oblique, orbicular luniform; peristome thin, simple; parietal region very thinly callosed.
The width of the shell is 4 mm. The height of the shell is 2 mm.[2]
Type specimen are stored in the collection of Academy of Natural Sciences in Philadelphia.[2]
