Xenophora peroniana is a species of large sea snail, a marine gastropod mollusc in the family Xenophoridae, the carrier shells.
The umbilicus is closed in adults, but narrowly open in juveniles.
A row of foreign objects is very prominent, obscuring more than half of the dorsal surface.
The base is slightly concave to almost flat, sculptured with fine, irregular, subspiral striae which run at almost right angles.
The columella is white but with a brown blotch around umbilical region in many specimens.
