IC 3715 (= PGC 4339550)
Discovered (Jan 27, 1904) by
Max Wolf (6-30)
A magnitude 16.7 spiral galaxy (type S??) in Coma Berenices (RA 12 44 21.3, Dec +20 01 26)
Apparent size 0.3 by 0.3 arcmin?

IC 3716
Recorded (Jan 23, 1900) by
Arnold Schwassmann
Either a nonexistent object in Virgo (RA 12 44 45.3, Dec +08 06 05)
or perhaps a magnitude 14 star at RA 12 44 45.0, Dec +08 06 29
Per Dreyer, IC 3716 (= Schwassmann #74, 1860 RA 12 37 40, NPD 81 07.9) is "very faint, very small, southwestern of 2", the other being IC 3719 (which see for images of the region). The position precesses to RA 12 44 45.3, Dec +08 06 05 (whence the position above), but there is nothing there save for the "other" galaxy, and the star listed above. Corwin suggests that Schwassmann's insistence that there were two nebulae in the area indicates the possible presence of a plate defect near the image of IC 3719, in which case the proper description for IC 3716 is "a nonexistent object"; but others feel that despite the half arcmin error in its position, the star to the west of IC 3719 is a better choice for the IC entry, hence my decision to mention both possibilities. Either way, IC 3716 is not a nebular object.

IC 3718 (= PGC 42944)
Discovered (Sep 14, 1900) by
Arnold Schwassmann (217)
A magnitude 13.2 spiral galaxy (type Sbc??) in Virgo (RA 12 44 45.3, Dec +12 21 03)
Apparent size 2.7 by 1.0 arcmin? Listed as a member (VCC 2006) of the Virgo Cluster.

IC 3719 (= PGC 42947)
Discovered (Jan 23, 1900) by
Arnold Schwassmann
A magnitude 14.6 irregular galaxy (type Irr?) in Virgo (RA 12 44 47.7, Dec +08 06 24)
Per Dreyer, IC 3719 (= Schwassmann #75, 1860 RA 12 37 43, NPD 81 07.5) is "extremely faint, very small, very questionable, northeastern of 2", the other being IC 3716. The position precesses to RA 12 44 48.3, Dec +08 06 29, right on the galaxy listed above, so the identification appears certain. Apparent size 0.6 by 0.45 arcmin. Listed as a member (VCC 2007) of the Virgo Cluster.
