Arp 223 (NGC 7585, PGC 70986 and others) is a member of Arp’s ‘Amorphous Spiral Arms’ class and is located approximately 163 million light-years away in Aquarius. This one looks a lot like a shell galaxy to me.
NGC 7576 (PGC 70948 and others) is located south west of Arp 223. It is also classified as a pair of galaxies but, much like Arp 223, one can’t really tell from the image.
