PGC 34546 (not =
NGC 3612)
Not an NGC object but long misidentified as NGC 3612
A magnitude 14.1 spiral galaxy (type Scd??) in Leo (RA 11 18 14.7, Dec +26 37 14)
Due to the longstanding misidentification as NGC 3612, see here for anything else

PGC 34695 (=
NGC 3627 = M66 = Arp 16; part of Leo Triplet = Arp 317)
A magnitude 8.9 spiral galaxy (type SAB(s)b?) in Leo (RA 11 20 15.1, Dec +12 59 24)
For anything else see NGC 3627

PGC 34767 (=
NGC 3631 = Arp 27)
A 10th-magnitude spiral galaxy (type SA(s)c) in Ursa Major (RA 11 21 03, Dec +53 10 11)
For anything else see NGC 3631

PGC 34881 (=
IC 2759 = HCG 51E)
A magnitude 14.1 lenticular galaxy (type E/SAB0?) in Leo (RA 11 22 13.3, Dec +24 19 02)
For anything else see IC 2759

PGC 34882 (= HCG 51B, but not =
IC 2759),
a member of Hickson Compact Group 51

A magnitude 14.5(?) galaxy (type SBbc?) in Leo (RA 11 22 14.2, Dec +24 18 01)
Historical Misidentification: Often misidentified as IC 2759, hence the warning about that mistake above.
Physical Information: Based on a recessional velocity of 8220 km/sec, a straightforward calculation indicates that PGC 34882 is 380 to 385 million light years away. However, for objects at such distances we should take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 370 million light years away at the time the light by which we see it was emitted, about 375 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and its apparent size of about 0.9 by 0.5 arcmin, it is 95 to 100 thousand light years across.

PGC 34898 (=
NGC 3651 = HCG 51A), a member of Hickson Compact Group 51
A magnitude 13.6 elliptical galaxy (type E0??) in Leo (RA 11 22 26.3, Dec +24 17 57)
For anything else see NGC 3651

PGC 34899 (= HCG 51F), a member of
Hickson Compact Group 51
A magnitude 14.8 lenticular galaxy (type S0? pec) in Leo (RA 11 22 26.3, Dec +24 17 45)
Physical Information: Based on a recessional velocity of 7530 km/sec, a straightforward calculation indicates that PGC 34899 is about 350 million light years away. However, for objects at such distances we should take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 340 million light years away at the time the light by which we see it was emitted, about 345 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and its apparent size of about 0.25 by 0.15 arcmin, the galaxy is about 25 thousand light years across.

PGC 34901 (= HCG 51G), a member of
Hickson Compact Group 51
A magnitude 15.5(?) elliptical galaxy (type E2?) in Leo (RA 11 22 28.2, Dec +24 17 43)
Physical Information: Based on a recessional velocity of 7530 km/sec, a straightforward calculation indicates that PGC 34901 is about 350 million light years away. However, for objects at such distances we should take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 340 million light years away at the time the light by which we see it was emitted, about 345 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and its apparent size of about 0.1 by 0.08 arcmin, the galaxy is about 10 thousand light years across.

For anything else see NGC 3653

PGC 34907 (= HCG 51D), a member of
Hickson Compact Group 51
A magnitude 15(?) spiral galaxy (type S(rs)ab?) in Leo (RA 11 22 30.6, Dec +24 18 00)
Physical Information: Based on a recessional velocity of 7530 km/sec, a straightforward calculation indicates that PGC 34907 is about 350 million light years away. However, for objects at such distances we should take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the galaxy was about 340 million light years away at the time the light by which we see it was emitted, about 345 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and its apparent size of about 0.35 by 0.35 arcmin, the galaxy is about 35 thousand light years across.
