This is something for telescopic observers and photographers of the moon, and... explorers/investigators of lunar maps, atlases, and globes.
There was once a not-so-small greenish colored map of the moon's near side (Rand Mc Nally). A similar map, about half the size of the original, was incorporated in Patrick Moore's Atlas of the Universe. On this map, nearly all of the I.A.U.'s officially recognized nomenclature was printed, but... also several names of unknown origin.
Here's a list of those mysterious names:
- Andreus hills (east of Gassendi)
- Golubiz cluster (a goup of hills between Campanus and Kies, at the southwestern part of Mare Nubium)
- Leon hills (near Wichmann in Oceanus Procellarum)
- Loro basin (east of Parrot C)
- Lothrop hills (between Brayley and Euler, aka Euler group)
- Mishqui basin (south of Mare Crisium)
- Mitika pk. (between Jansen F and Jansen K in Mare Tranquillitatis)
- Morotcha (north of Mare Vaporum)
Of these names, the Golubiz cluster is the only one which appeared as an "extra" on the original Rand Mc Nally moonmap. It is not included in Patrick Moore's Atlas of the Universe.
Now, who of you connoisseurs of the moon (read: experts of lunar cartography and nomenclature) could tell me more about these mysterious names. They are not included in Ewen A. Whitaker's book Mapping and Naming the Moon, a history of lunar cartography and nomenclature (1999), which is rather strange.

Note: the Loro basin, to the east of Parrot C, is the location of a less known (read: very unknown) swirl formation like Reiner Gamma in Oceanus Procellarum. This swirl east of Parrot C was officially discovered only several years ago, but... it was already detectable on a Full Moon photograph which appeared in one of the monthly ASTRONOMY magazines of 1984! (who was the early discoverer of that swirl formation at the Loro basin? Me).

Also interesting to know: the odd-shaped formation east of the Andreus hills (north of Agatharchides) which contains the hillock Herigonius Eta, was once known as The Helmet during the Apollo program. This nickname is, afaik, only mentioned in the book APOLLO 16 - PRELIMINARY SCIENCE REPORT, page 28-8. Was it thus nicknamed because it look'd very much like a helmet? Well, one could see something like the helmet of a Formule 1 driver in it, but... I think we should ask about it to THE KING and his pupils (moon specialist Farouk El-Baz and the orbiting astronauts of Apollo's scientific J-missions).

This (The Helmet east of the Andreus hills) and Jim Lovell's Mount Marilyn (the triangle-shaped peninsula Secchi Theta) are two of the largest NASA-nicknamed formations on the moon's near side. No large telescopes are needed to observe these formations!
