DeLisle Stewart discovered IC 4682 = DS 454 on a plate taken on 20 Aug 1900 at Harvard's Arequipa Station in Peru. He noted "vF, cS, cE at 140°, stell N."

600/800mm - 24" (4/12/08 - Magellan Observatory, Australia): at 200x appeared bright, moderately large, elongated 3:2 NW-SE, 1.5'x1.0', fairly well concentrated with a brighter core. Several mag 13-14 stars surround the galaxy with a couple of faint stars at both the NW and NE edge of the halo. This is fairly bright galaxy to be missed by John Herschel and 54' E is a bright pair of galaxies, IC 4704 and IC 4705, which were also missed by Herschel.
