We present a catalog of 416 extended, resolved, disk and ringlike objects as detected in the MIPSGAL 24 micron survey of the Galactic plane. This catalog is the result of a search in the MIPSGAL image data for generally circularly symmetric, extended bubbles without prior knowledge or expectation of their physical nature. Most of the objects have no extended counterpart at 8 microns or 70 microns with less than 20% ...
