Original Description of Rimella peruviana by Olsson, 1931, p. 189:
- "Shell of medium size, a spire of moderate length and a sculpture of coarse riblets and finer spirals; nucleus unknown; post-nuclear whorls 4+, the spire-whorls fairly large and about one-half the length of the whole shell; rib-like varices are present on some of the spire-whorls and roughly spaced about 120 degrees apart; on the last whorl, a varical rib is present, not quite opposite the outer lip so that the ventral side of the shell appears slightly depressed and the dorsal side convex to slightly humped; sculpture consists of even, linear riblets which number about 21 on the last turn; the spaces between the riblets are wider, concave and marked with fine spiral lines; anterior canal and anterior side of aperture broken; the posterior canal is continued as in Rimella fissurella along a ridge of callus to the tip of the spire."
