The New Student's Reference Work/Myriapoda

Myriapoda (mĭr′ ī-ăp′ ṓ-dȧ), a class of jointed animals containing the centipedes and thousand-legged worms.  The name signifies many-footed.  The body is worm-like and jointed.  There is a pair of legs for each joint.  The head carries antennas, jaws and eyes, and there is no distinction between thorax and abdomen.  The myriapods form a group equivalent, respectively, to that of the Crustacea, spiders and insects, and these four classes make the subkingdom of arthropoda.  See Arthropoda and Centipede.
