NGC 4862 (which is probably also IC 3999) and NGC 4863 were found by Frank Leavenworth at Leander McCormick in 1886. Both galaxies are off their nominal RA's and are just faint enough that Bigourdan could not find them. He also searched in the wrong direction from his comparison star on one night. I think it was this confusion that led him to rediscover NGC 4862 (see IC 3999 for that story). Both objects are positively identified by the sketches that Leavenworth made of them.
Herbert Howe did locate NGC 4862 and gave a corrected position for it, copied into the IC Notes. He states that "Another was suspected perhaps 5 arcmin south of this one." That is about the correct distance north to NGC 4863. Did Howe get his directions reversed, just as Bigourdan did when he was looking for NGC 4862 in this field?
The RNGC (Sulentic and Tifft 1973) notes that this is a 15.0 mag galaxy. Their coded description reads EON,MBM.
