IC 4300 (= PGC 47912)
Discovered (Jun 16, 1903) by Stephane Javelle
A magnitude 15.1 elliptical galaxy (type E2?) in Canes Venatici (RA 13 35 25.1, Dec +33 25 11)
Historical Identification: Per Dreyer, IC 4300 (= Javelle #1261, 1860 RA 13 29 04, NPD 55 51.9) is "faint, very small, diffuse".
Physical Information: Based on a recessional velocity of 12090 km/sec, a straightforward calculation indicates that IC 4300 is about 565 million light years away. However, for objects at such distances we should take into account the Universal expansion during the time it took their light to reach us. Doing that shows that the galaxy was about 535 million light years away at the time the light by which we see it was emitted, about 545 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 0.45 by 0.35 arcmin, it is about 70 thousand light years across.

Given that and its apparent size of 1.25 by 0.2 arcmin, it is about 125 thousand light years across.

IC 4317 (= PGC 87672)
Discovered (Jun 21, 1895) by Stephane Javelle
A magnitude 14.7 spiral galaxy (type Sa?) in Boötes (RA 13 41 45.8, Dec +27 06 23)
Historical Identification: Per Dreyer, IC 4317 (= Javelle #1271, 1860 RA 13 35 19, NPD 62 11.5) is "faint, small, round, nuclear, mottled but not resolved". The position precesses to RA 13 41 48.8, Dec +27 05 59, just over half an arcmin southeast of the galaxy listed above, so the identification should be certain. In fact, per Corwin, if Javelle's measurements are re-reduced using a more accurate modern position for his comparison star, the error in position becomes mere arcseconds, making the identification even more certain. However, Corwin also states that PGC 48479, about 6 arcmin to the south, is often misidentified as IC 4317, so it is discussed immediately below.

Discovered (Apr 20, 1897) by Lewis Swift (and later listed as IC 4338)
A magnitude 11.3 spiral galaxy (type SBc??) in Virgo (RA 13 52 54.5, Dec -01 06 49)
Historical Identification: Per Dreyer, IC 4338 (= Swift list XI (#161), 1860 RA 13 45 30, NPD 90 26.1) is "extremely faint, very large, considerably extended north-south, faint star near each end". (cf Corwin)
Physical Information: Given the duplicate entry, see NGC 5334 for anything else.
IC 4339 (not = IC 4341)
Recorded (Jun 19, 1897) by Stephane Javelle
A magnitude 12(?) star in Canes Venatici (RA 13 53 28.9, Dec +37 32 19)
Historical Identification: Per Dreyer, IC 4339 (= Javelle #1276, 1860 RA 13 47 26, NPD 51 46.2) is "faint, small, round, mottled but not resolved". The position precesses to RA 13 53 28.8, Dec +37 32 22, right on the star listed above, so the identity is certain. However, presumably due to its proximity to IC 4341 (which see for an image), IC 4339 is sometimes misidentified as a duplicate of IC 4341 (hence the warning above).
IC 4340 (= PGC 49364)
Recorded (Jun 26, 1896) by Stephane Javelle
A magnitude 14.0 lenticular galaxy (type S0??) in Canes Venatici (RA 13 53 33.6, Dec +37 23 12)
Historical Identification: Per Dreyer, IC 4340 (= Javelle #1277, 1860 RA 13 47 31, NPD 51 54.4) is "faint, small, round, gradually brighter middle".
Physical Information: Apparent size 1.0 by 0.7 arcmin?
IC 4341 (= PGC 49366, and not = IC 4339)
Discovered (Jun 18, 1897) by Stephane Javelle
A magnitude 13.9 spiral galaxy (type Sc?) in Canes Venatici (RA 13 53 34.3, Dec +37 31 19)
Historical Identification: Per Dreyer, IC 4341 (= Javelle #1278, 1860 RA 13 47 32, NPD 51 46.3) is "faint, small, round, mottled but not resolved, 12th magnitude star near". The position precesses to RA 13 53 34.8, Dec +37 32 16, less than an arcmin north of the galaxy listed above, and the nearby star makes the identity certain. (The star was recorded by Javelle the next night as his #1276, which was listed by Dreyer as IC 4339, and presumably as a result of their proximity, that entry is sometimes misidentified as a duplicate of IC 4341, hence the warning above.)
Physical Information: Apparent size 0.8 by 0.75 arcmin.

A magnitude 14.6 spiral galaxy (type Sbc??) in Boötes (RA 13 54 22.0, Dec +25 09 09)
Historical Identification: Per Dreyer, IC 4342 (= Javelle #1279, 1860 RA 13 47 52, NPD 64 09.5) is "faint, small, round, a little brighter middle, mottled but not resolved".
Physical Information: Apparent size 0.8 by 0.3 arcmin?

A magnitude 14.0 lenticular galaxy (type E/S0??) in Boötes (RA 13 54 55.7, Dec +25 07 21)
Historical Identification: Per Dreyer, IC 4343 (= Javelle #1280, 1860 RA 13 48 26, NPD 64 11.4) is "faint, small, round, nuclear, mottled but not resolved".
Physical Information: Apparent size 1.0 by 0.5 arcmin?

Historical Identification: Per Dreyer, IC 4344 (= Javelle #1281, 1860 RA 13 48 44, NPD 64 16.6) is "faint, very small, nuclear, stellar".
