Arp 187 (MCG-02-13-040a, PGC 16691 and others), the odd galaxy just left of the bottom center, is part of Arp’s Galaxies (not classifiable as S or E): Narrow filaments class.

IC 401 (PGC 16672 and others) is the large spiral near the top.

These are located below the witch head nebula in Eridanus.
