Shell small, rounded-oval, conical, apex elevated, situated at the anterior fourth of the shell's length ; front slope steep, straight or concave, posterior slope convex. Surface smooth, showing faint lines of growth. Color reddish-buff or orange; inside of the same color, the border flesh-colored. Length 5, breadth 4, alt. 2,5 mm.

This little shell is of a more erectly conical form than Iothia fulva, and lacks radiating sculpture. It is smaller than T. virginea and not radiately painted, besides having the summit more anterior and more elevated. The specimens before me are from Greenland. It has been reported from the New England coast, but I am not sure of the correctness of the determination.
