Varveled \Var"veled\, a.
   Having varvels, or rings. [Written also {varvelled}, and
   {vervelled}.]

   Note: In heraldry, when the jesses attached to the legs of
         hawks hang loose, or have pendent ends with rings at
         the tips, the blazon is a hawk (or a hawk's leg) jessed
         and varveled.
