Stomatolina rufescens, common name the northern wide-mouthed shell, is a species of small sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.
They are rather convex, concentrically striated with rather unequal acute spiral ridges.
The aperture is oblong, two-thirds the diameter of the shell in width.
The throat is silvery pearly, with a pale reddish edge.
