Webster's Revised Unabridged Dictionary
    • n. pl Myriapoda (Zoöl) 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 antennæ, three pairs of mouth organs, and numerous tracheæ, similar to those of true insects. The larvæ, when first hatched, often have but three pairs of legs. See Centiped Galleyworm Milliped.☞ The existing Myriapoda are divided into three orders: Chilopoda Chilognatha or Diplopoda, and Pauropodasee these words in the Vocabulary). Large fossil species (very different from any living forms) are found in the Carboniferous formation.

    • n myriapoda A class of articulate animals of the subkingdom Arthropoda; the centipeds and millepeds. They have a long worm-like body of cylindric or flattened form, composed of from 10 to more than 200 rings or segments, scarcely or not at all differentiated into thorax and abdomen; a distinct head; and one or two pairs of legs to each somite of the body. There is a pair of antennæ, and the jaws are mandibulate. Respiration is tracheal, through small pores or spiracles along the sides of the body. Reproduction is oviparous or ovoviviparous, and the sexes are distinct. There is no proper metamorphosis, but the young have fewer segments and legs than the adults, the normal number being acquired by successive molts. Excluding the pauropods and malacopods, the Myriapoda occur under two well-defined types, forming two orders—the Chilognatha or Diplopoda, millepeds or gally-worms, and the Chilopoda or Syngnatha, centipeds. See cuts under centiped, milleped, cephalic, basilar, and myriapod.
