Antiguraleus permutatus is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae.

(Original description) The small shell has an ovate-cylindrical shape and is rather gibbous.

Its sculpture shows on the first adult whorl are ten narrow, elevated, wide-spaced radials.

These degenerate as growth advances; from the last suture they persist as downward dashes, and vanish on the anterior half of the shell.

Near the summit is excavated a broad and shallow sinus, and at two-thirds of its length occurs a stromboid insinuation A thin free edge reaches over the aperture.
