Background image source
- Auwers Tholus (an unofficial name from D.Caes for the curious dome-like formation with craterlet on top, located south-southwest of Auwers itself).
- Bessel Ray (an informal name for the mysterious high-albedo ray which runs across Mare Serenitatis and crater Bessel, see Chart 11 in the 21st Century Atlas of the Moon, C.A.Wood/ M.J.S.Collins).
- Brackett (near Fossae Plinius, see Lunar Topophotomap 42C4S1).
- Catena Brigitte (at the region of the supposed volcanic cones west-southwest of Mons Argaeus).
- Dawes (and its kind of tan colored halo, surrounded by the bluish-grey of Mare Tranquillitatis) (seems to have been called Insula by J.Hewelcke).
- Deseilligny's elongated depression (a rather dull nickname from D.Caes for the irregular crater south of Deseilligny, at 20° North/ 20°30' East).
- Dorsa Aldrovandi
- Dorsa Lister (southern part of the Serpentine Ridge).
- Dorsa Smirnov (northern part of the Serpentine Ridge).
- Dorsum Azara
- Dorsum Nicol
- Elongated depression (a rather dull nickname from D.Caes for the weird oblong crater southwest of Mons Argaeus, near the supposed volcanic cones).
- Finsch (perhaps the same kind of formation as the curious ring west of Carlini L and the shallow crater west of Laplace F, both in Mare Imbrium).
- Fossae Pavlova (a disallowed name for the system of rilles immediately east of Dorsa Aldrovandi, see Lunar Topographic Orthophotomaps 42-B3, 42-C2).
- Ghost of Posidonius (a nickname from D.Caes for the more-or-less circle shaped arrangement of several wrinkle ridges southwest of Posidonius, on Mare Serenitatis) (this "ghost" was already discovered during the preceding century and was depicted on lunar map SLC-B3).
- Insula Cyanea Europa (J.Hewelcke's disallowed name for a vague bright area north of Tacquet) (mentioned as Insula Cyanea on J.Hewelcke's map).
- Isis (at the region of the supposed volcanic cones west-southwest of Mons Argaeus).
- Jansen E (the most awful nitpickers of selenography might have noticed the absence of the label Jansen E at the craterlet in the lower right corner of chart 24 in Antonin Rukl's printed version of his atlas. The same absence is noticeable at the upper right corner of chart 35).
- Jerik (at the region of the supposed volcanic cones west-southwest of Mons Argaeus).
- Le Monnier (right margin of Chart 24, see Chart 25).
- Luna 21 with Lunokhod 2 (soft landed at the southern part of Le Monnier's floor).
- Mare Serenitatis (occupying almost the whole of Chart 24) (Van Langren's Mare Eugenianum, J.Hewelcke's Pontus Euxinus).
- Mare Tranquillitatis (the northern part of it, occupying the lower right section of Chart 24) (Van Langren's Mare Belgicum, J.Hewelcke's Pontus Euxinus).
- Mary (at the region of the supposed volcanic cones west-southwest of Mons Argaeus).
- Mons Argaeus (right margin of Chart 24, see Chart 25).
- Osiris (at the region of the supposed volcanic cones west-southwest of Mons Argaeus).
- Paludes Inferiores (J.Hewelcke's disallowed name for the ray north-northeast from Bessel).
- Plinius (Van Langren's Eugeniae, J.Hewelcke's Insula Apollonia).
- Posidonius Gamma (a high-albedo craterlet at the centre of the upper margin of Chart 24, on the most northern section of Dorsa Smirnov) (Posidonius Gamma seems to be of the same kind of formations as Linne, Lassell D, and Werner D, because a number of observers reported brightness-variations in and around these craterlets before, during, and after Full Moon phase) (note: on the LROC's Act-React Quick Map this craterlet is labeled as Posidonius Y).
- Promontorium Archerusia (one of J.Hewelcke's original names which are still officially recognized by the IAU).
- Rima Dawes (immediately northeast of Dawes, almost touching this crater's rim) (with its southeastern continuation it looks very much like some sort of "bow wave" or "bow shock", it's as if crater Dawes is moving eastward through the northern part of the Sea of Tranquillity).
- Rima Marcello (at the region of the supposed volcanic cones west-southwest of Mons Argaeus).
- Rima Reiko (at the region of the supposed volcanic cones west-southwest of Mons Argaeus).
- Rimae Menelaus (once known as Fossae Menelaus, see Lunar Topographic Orthophotomap 42-D3).
- Rimae Plinius (once known as Fossae Plinius, see Lunar Topographic Orthophotomaps 42-C3, 42-C4) (and Lunar Topophotomap 42C4S1).
- Robert (at the region of the supposed volcanic cones west-southwest of Mons Argaeus).
- Serpentine Ridge (a well-known informal name for one of the most observed wrinkle ridges, see also Dorsa Lister and Dorsa Smirnov).
- Smiley (a nickname from D.Caes for the curious snake like sinuous rille (the smiling mouth) and craterlet Le Monnier KA (one of the two eyes) at 28° North/ 28° East, see Figure 190 in Chapter 6; Sinuous Rimae, page 1 of 3, in NASA SP-362 Apollo Over The Moon: a view from orbit).

- There's a distinct color-difference at the lower part of this region (the southern part of Mare Serenitatis and the northern part of Mare Tranquillitatis). Mare Serenitatis looks quite yellowish, while Mare Tranquillitatis looks rather bluish. This color-difference is observable through all sorts of telescopes and giant binoculars; especially during the days of Full Moon.

Apollo; Atmospheres and Soundtracks
- Rimae Plinius, Brackett, Dorsum Nicol, the northern part of crater Plinius, and Promontorium Archerusia, are depicted on the cover of the album APOLLO: ATMOSPHERES AND SOUNDTRACKS by Brian Eno, Daniel Lanois, and Roger Eno (1982). Apollo 17's reproduced orbital Hasselblad photograph (AS17-150-23069) looks impressive on the L.P.-edition which appeared in the early eighties!
