Named Features

• Aegyptus (regio) (J.Hewelcke's disallowed name for the southwestern highlands).
• Byrgius A (once called La Paz by H.P.Wilkins) (Byrgius A is the bowl-shaped crater with high-albedo ejectablanket around it, at the left margin of Chart 51) (this was Van Langren's Malvezzi, J.Hewelcke's Mons Acabe).
• Cavendish (J.Hewelcke's Mons Ajax).
• de Gasparis
• De Vico
• Doppelmayer Pyroclastics (an informal name, incorporated on Chart FM3, page 82 in the 21st Century Atlas of the Moon (C.A. Wood/ M. Collins). This is the low-albedo region at the southwestern part of Mare Humorum).
• Eye (a nickname from D.Caes for Liebig J at the northern part of Rimae Doppelmayer) (Liebig J shows a rare bright "iris" at its inner slopes).
• Fluvius Nilus (J.Hewelcke's disallowed name for the dark streaks at Billy-Mersenius).
• Fontana
• Giovanelli (Van Langren's disallowed name for Mersenius Zeta).
• Guldini (Van Langren's disallowed name for Palmieri Alpha).
• Henry
• Henry Frères
• Jiyah (a disallowed name from H.P.Wilkins for Mersenius D).
• Lacus de Gasparis-Liebig-Palmieri (an unofficial name from D.Caes for the low-albedo region near the southwestern part of Mare Humorum's rim) (seems to have been called Paludes Arabiae by J.Hewelcke).
• Landerer (a disallowed name from H.P.Wilkins for Mersenius B).
• Liebig
• Magini (Van Langren's disallowed name for Liebig Gamma).
• Mare Humorum (Van Langren's Mare Venetum) (the most western part of it, at the right margin of Chart 51).
• Mersenius
• Mons Sacer (J.Hewelcke's disallowed name for the western border of Mare Humorum).
• Palmieri
• Paludes Arabiae (J.Hewelcke's disallowed name for the low-albedo area at de Gasparis and Palmieri).
• Paul Henry Delta (elevation north of both the Henry craters) (see Chart 78 in the Times Atlas of the Moon).
• Peninsula Fulminum (Riccioli's discontinued name for the region between Gassendi and Letronne, depicted near the upper right corner of Chart 51).
• Percy Mountains (a disallowed name from W.R.Birt for the mountainous region at the northwestern part of Mare Humorum's rim).
• Rima Billy
• Rimae de Gasparis
• Rimae Doppelmayer
• Rimae Liebig (a discontinued IAU name).
• Rimae Mersenius
• Rimae Palmieri
• Rimae Zupus
• Rupes Liebig
• Terra Caloris (Riccioli's discontinued name for the lower left part of Chart 51).
• Terra Iustitiae (Van Langren's disallowed name for the lower left part of Chart 51).
• Unexpected remains of a possible basin (see this page).
• Vieta (J.Hewelcke's Mons Casius) (note: together with the IAU's Fourier this is the first one of J.Hewelcke's Montes Casius, because there's also a second one at Chart 52: the IAU's Agatharchides P) (Mons Casius should not be confused with the unofficial name Mons Caes near Helmholtz).
• Zupus (Van Langren's Flumen S. Augustini, Riccioli's Fontana).
