Labes (plural labēs) is a word of Latin origin denoting a steep decline or collapse, especially at ground level. It is used on Mars to refer to huge landslides, all located without exception within Valles Marineris.
Latitudes and longitudes in white are planetocentric. Those in orange use the older planetographic system.

Strictly speaking, there are no lacus (plural lacūs) on Mars as described in the nomenclature, but there are still eight areas named "Lacus". They are all albedo features.

In planetology, a labyrinthus (plural labyrinthi) is a complex network of intersecting valleys and canyons, most often cutting through a plateau (planum). The word is borrowed from Latin ("labyrinth"). Labyrinths have been described on Mars and Venus. This type of formation typically corresponds to a crustal uplift. On Mars it is in particular the case of Noctis Labyrinthus, in the north of the high plateau of Syria Planum, starting point of the canyons of Valles Marineris.

Mensa (plural mensae) is a Latin word for table. This word has the same root as the Spanish term Mesa also meaning "table" and used in geomorphology a rise of land with a flat top and cliff sides. Mensa is used here to describe small plateaus with flat, horizontal tops, bordered by generally steep cliffs.
The [names in grey and italics] in the tables are dropped or moved, referenced here because they may appear in older documents. Latitudes and longitudes in white are planetocentric. Those in orange use the older planetographic system.
