\Lab`y*rin"thi*ci\, n. pl. [NL. See {Labyrinth}.]
(Zo["o]l.)
An order of teleostean fishes, including the Anabas, or
climbing perch, and other allied fishes.
Note: They have, connected with the gill chamber, a special
      cavity in which a labyrinthiform membrane is arranged
      so as to retain water to supply the gills while the
      fish leaves the water and travels about on land, or
      even climbs trees.
