The spiral sculpture between the suture and the periphery features numerous flat, subequal, strap-like bands separated by narrower, shallow channels.

The periphery displays a low, broad prominence that gives the effect of a keel, adorned with several similar but larger, stronger, and more widely spaced bands, often arranged in pairs, with fine subsidiary spiral striations.

A wide, deep anal sulcus is present on the posterior slope of the whorl, about midway between the suture and the periphery.

The columella is short and twisted, obliquely truncate in front, gyrate, but not axially pervious, with a touch of brown on the edge.

The subspecies Aforia persimilis blanca was found off Cape Blanco, Oregon, United States, North Pacific Ocean at a depth of 1946 m.
