Radiated Animals. Our illustration represents the figure of a common Starfish, or "Five-Finders." The limbs, or arms, are arranged like rays proceeding from a centre, and from this circumstance it is termed a "rayed," or "radiated animal." All with this rayed appearance have, of course, the same appellation, and, along with others, constitute class Radiata. The rayed appearance is not, however, so obvious in many of these animals as in the Starfish. Radiated animals are divided into four classes, viz Infusoria, or Infusory Animalcules.
