IC 3716 and IC 3719 are two of Schwassmann's nebulae found on his plates of the Virgo Cluster. He describes both similarly (eF, vS) though adds two question marks after the entry for IC 3719. He also has a note: "Clearly distinct from one another," probably added since the two objects are separated by less than an arcminute.
Unfortunately, there is only one galaxy in the area. Its position is about 10-15 arcsec west of the position for IC 3719, but the place of IC 3716 is even further west, and about 30 arcsec south as well. At Schwassmann's RA for IC 3716, there is a star -- but it is about 30 arcsec north of his Dec.
I suspect plate flaws superposed on the galaxy that is there. Since the position for IC 3719 is closest to the galaxy, I'm going to adopt that number for it -- though with some trepidation.― IC Notes by Harold Corwin
