Myriapoda \Myr`i*ap"o*da\, n. pl. [NL., fr. Gr. ? numberless +
   -poda.] (Zo["o]l.)
   A class, or subclass, of arthropods, related to the hexapod
   insects, from which they differ in having the body made up of
   numerous similar segments, nearly all of which bear true
   jointed legs. They have one pair of antenn[ae], three pairs
   of mouth organs, and numerous tracha[ae], similar to those of
   true insects. The larv[ae], when first hatched, often have
   but three pairs of legs. See {Centiped}, {Galleyworm},
   {Milliped}.

   Note: The existing Myriapoda are divided into three orders:
         Chilopoda, Chilognatha or Diplopoda, and Pauropoda (see
         these words in the Vocabulary). Large fossil species
         (very different from any living forms) are found in the
         Carboniferous formation.
