Shagreen \Sha*green"\, n. [F. chagrin, It. zigrino, fr. Turk.
   saghri the back of a horse or other beast of burden,
   shagreen. Cf. Chagrin.]
   1. A kind of untanned leather prepared in Russia and the
      East, from the skins of horses, asses, and camels, and
      grained so as to be covered with small round granulations.
      This characteristic surface is produced by pressing small
      seeds into the grain or hair side when moist, and
      afterward, when dry, scraping off the roughness left
      between them, and then, by soaking, causing the portions
      of the skin which had been compressed or indented by the
      seeds to swell up into relief. It is used for covering
      small cases and boxes.
      [1913 Webster]

   2. The skin of various small sharks and other fishes when
      having small, rough, bony scales. The dogfishes of the
      genus Scyllium furnish a large part of that used in the
      arts.
