Toledonia bullata is a species of sea snail, a marine gastropod mollusk in the family Ringiculidae.

The small shell is thin, smooth, whitish and covered with a most delicate straw colored epidermis.

The whole surface is marked with regularly arranged, deep, linear, revolving grooves, of which there are about five on the upper whorls, and about sixteen on the body whorl.

The columella, about one-third the length of the aperture, is flat, and divided by a single groove.
