Arp 219 (UGC 2812, PGC 13489 and others) is the odd, distorted galaxy at the center. Part of Arp’s, ‘Galaxies (not classifiable as S or E) - adjacent loops’ class, this one is located approximately 460 million light-years away in Eridanus.
UGC 2814 (PGC 13496 and others) is the spiral to the left (east) of Arp 219. It is suspected that this one is interacting with Arp 219 but it is not in Arp’s original image.
