Century Dictionary and Cyclopedia

  1. n. An American nymphalid butterfly, Eugonia j-album: more fully called the Compton tortoise.
  2. n. Same as tortoise-beetle.
  3. n. A turtle; any chelonian or testudinate; a member of the order Chelonia or Testudinata (see the technical terms). It is not known what species the name originally designated; probably a land-tortoise of southern Europe, as Testudo græca. There is a tendency to distinguish terrestrial chelonians from aquatic ones, the former as tortoises, the latter as turtles; yet tortoiseshell is fixed as the name of the commercial product of certain sea-turtles. (See box-tortoise, land-tortoise, terrapin, turtle, mud-turtle, sea-turtle.) Tortoises or some kind are found in most parts, and especially the warmer parts, of the world; the species are numerous—those of the land and of fresh waters much more so than the marine forms. See also cuts under carapace, Chelonia, Chelonidæ, Chelydidæ, Cinixyinæ, Cinosternum, Cistudo, plastron, Pyxis, Testudo, Testudinata, and terrapin.
  4. n. A movable roof formerly used to protect the soldiers who worked a battering-ram. Sometimes it was formed by the soldiers holding their shields flat over their heads so as to overlap one another. See testudo.

Wiktionary
