An investigation based on deep U.K. Schmidt Telescope direct plates has discovered a previously uncataloged dwarf irregular galaxy which, it is proposed, is associated with the 1225 + 0146 extragalactic H I cloud. This new optical feature is characterized by a number of knots embedded in low surface brightness material about 1 arcmin in extent. The object is classified as an M(B) = -15.5 Magellanic type dwarf irregular galaxy about 5 kpc in extent. The brightest knot is considered to be an H II region.
