IC 1252 = IC 4649. This identity was recognized by Bigourdan himself: It is Big 217 = Big 429, and apparently stems from some error in his record keeping (there are five others in the same RA range with duplicated numbers in his lists). He has the two as being identical in his Table II of new nebulae (Table II has the "novae" in RA order), but has them at different RAs in Table I (this lists them in order of Bigourdan's own number).

He attempted to measure a position for the object on only one of the three nights on which he saw it -- there is a considerably brighter star only 30 arcsec to the east which interferred with his observation. His single position falls between the star and the galaxy.
