Articula’ta

Articula’ta or ARTICULATED ANIMALS, one of the great primary divisions of the Animal Kingdom, according to the system of Cuvier (see ZOOLOGY). It included those animals of which the body is divided into a number of distinct joints—viz. the higher worms or Annelids, and also the Insects, Crustaceans, Arachnids, and Myriapods. The four latter groups were separated from the Annelida (q.v., and see also WORMS) by Von Siebold, on account of their possession of hollow jointed limbs, into a separate sub-kingdom, Arthropoda (q.v.).
