Scutibranchiata \Scu`ti*bran`chi*a"ta\, n. pl. [NL. See
   {Scutum}, and {Branchia}.] (Zo["o]l.)
   An order of gastropod Mollusca having a heart with two
   auricles and one ventricle. The shell may be either spiral or
   shieldlike.

   Note: It is now usually regarded as including only the
         Rhipidoglossa and the Docoglossa. When originally
         established, it included a heterogenous group of
         mollusks having shieldlike shells, such as Haliotis,
         Fissurella, Carinaria, etc.
