from The Century Dictionary and Cyclopedia

  • A class of Echinodermata containing globular or cup-shaped echinoderms, having, normally, jointed arms furnished with pinnules, and stalked and fixed during some or all of their lives: so called from the resemblance of their rayed bodies, borne upon a jointed stem, to a lily or tulip.
  • The typical order of the class Crinoidea, having the body cup-shaped or calyx-like. the dorsal or aboral surface furnished with hard calcareous plates, the ventral or oral aspect coriaceous, and the body stalked and rooted, at least for some period if not continuously, and provided with five or more radiated segmented arms bearing pinnules and disconnected from the visceral cavity.
