Source : Webster's Revised Unabridged Dictionary (1913)

Gastropoda \Gas*trop"o*da\, n. pl., [NL., fr. Gr. ?, ?, stomach
   + -poda.] (Zo["o]l.)
   One of the classes of Mollusca, of great extent. It includes
   most of the marine spiral shells, and the land and
   fresh-water snails. They generally creep by means of a flat,
   muscular disk, or foot, on the ventral side of the body. The
   head usually bears one or two pairs of tentacles. See
   {Mollusca}. [Written also {Gasteropoda}.]

   Note: The Gastropoda are divided into three subclasses; viz.:
         ({a}) The Streptoneura or Dioecia, including the
         Pectinibranchiata, Rhipidoglossa, Docoglossa, and
         Heteropoda. ({b}) The Euthyneura, including the
         Pulmonata and Opisthobranchia. ({c}) The Amphineura,
         including the Polyplacophora and Aplacophora.
