Actually, Sir William's original description was "...opening with a branch, or two nebulae very faintly joined. The south is smallest." It's a recurring story of discoveries broken up by subsequent observers. I am yet to see the tails. My most recent observation was ust a quick look two weeks ago: "N component itself is a ring and a tail. Good separation of the S component [dark break on E side, not just the gulf]. 12" SCT, 13 mm Ethos, SQM 21.8-9.
