Articulata \Ar*tic`u*la"ta\ ([aum]r*t[i^]k`[-u]*l[=a]"t[.a]), n.
   pl. [Neut. pl. from L. articulatus furnished with joints,
   distinct, p. p. of articulare. See {Article}, v.] (Zo["o]l.)
   1. One of the four subkingdoms in the classification of
      Cuvier. It has been much modified by later writers.

   Note: It includes those Invertebrata having the body composed
         of a series of ringlike segments (arthromeres). By some
         writers, the unsegmented worms (helminths) have also
         been included; by others it is restricted to the
         Arthropoda. It corresponds nearly with the Annulosa of
         some authors. The chief subdivisions are Arthropoda
         (Insects, Myriapoda, Malacopoda, Arachnida,
         Pycnogonida, Crustacea); and Anarthropoda, including
         the Annelida and allied forms.

   2. One of the subdivisions of the Brachiopoda, including
      those that have the shells united by a hinge.

   3. A subdivision of the Crinoidea.
