Scallop \Scal"lop\ (?; 277), n. [OF. escalope a shell, probably
   of German or Dutch origin, and akin to E. scale of a fish;
   cf. D. schelp shell. See {Scale} of a fish, and cf.
   {Escalop}.] [Written also {scollop}.]
   1. (Zo["o]l.) Any one of numerous species of marine bivalve
      mollusks of the genus Pecten and allied genera of the
      family {Pectinid[ae]}. The shell is usually radially
      ribbed, and the edge is therefore often undulated in a
      characteristic manner. The large adductor muscle of some
      the species is much used as food. One species ({Vola
      Jacob[ae]us}) occurs on the coast of Palestine, and its
      shell was formerly worn by pilgrims as a mark that they
      had been to the Holy Land. Called also {fan shell}. See
      {Pecten}, 2.

   Note: The common edible scallop of the Eastern United States
         is {Pecten irradians}; the large sea scallop, also used
         as food, is {P. Clintonius, or tenuicostatus}.

   2. One of series of segments of circles joined at their
      extremities, forming a border like the edge or surface of
      a scallop shell.

   3. One of the shells of a scallop; also, a dish resembling a
      scallop shell.

Scallop \Scal"lop\, v. t. [imp. & p. p. {Scalloped}; p. pr. &
   vb. n. {Scalloping}.]
   1. To mark or cut the edge or border of into segments of
      circles, like the edge or surface of a scallop shell. See
      {Scallop}, n., 2.

   2. (Cookery) To bake in scallop shells or dishes; to prepare
      with crumbs of bread or cracker, and bake. See {Scalloped
      oysters}, below.
