Object name: ARP190
Arp classifies this one under "Galaxies (not classifiable as E or S): Narrow filaments". Odd as the two galaxies involved seem to be obvious spirals. But it appears Arp thought there were three, one stellar but he never got spectral data on it to know for sure. More on this below. It is also cataloged as UGC 2320. UGC 2320 also includes the galaxy below those with the filament.
