IC 3273 = NGC 4356. Here is another case where Schwassmann missed the NGC number on one of the nebulae that he measured on a Heidelberg plate. Both his position and William Herschel's are good, so Dreyer had an opportunity to equate them, too. The identity was first suggested by Adelaide Ames in her 1930 Virgo Cluster catalogue.
