Origin: 1790–1800; < NL, appar. special use of L lemurēs (pl.) ghosts, specters
le·mur (lē'mər) n. Any of several small arboreal, mostly nocturnal primates chiefly of the family Lemuridae of Madagascar and adjacent islands, having large eyes, a long slim muzzle, and a long tail.
[New Latin Lemur, genus name, back-formation from Latin Lemurēs, lemures (from their ghostly appearance and their nocturnal habits).]
"nocturnal Madagascar mammal," 1795, coined by Linnaeus, from L. lemures (pl.) "spirits of the dead" in Roman mythology. So called for its nocturnal habits and ghostly stares. Lemuria (1864) was the name given by P.L. Sclater to a hypothetical ancient continent connecting Africa and Southeastern Asia (and including Madagascar), which was hypothesized to explain phenomena now accounted for by continental drift.
