IC 3919 is marked on the print of the original plate, and is 3.5 arcmin north of Wolf's published position. Since other of the nebulae in this list are also off by the same amount (e.g. IC 3893), I think that the discrepancy represents a digit error in Wolf's y-axis measurement. There is a larger but fainter galaxy about 1.5 arcmin east of the IC galaxy. It is not visible on the print of the original plate.
