&?; numberless + -poda.] (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.

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.
