● (syn. Strix Ϯ Ural Owl S. uralensis) "THE SURNS (Surnia, Dumeril)  ...  The species of the Uralian mountains (Str. uralensis, Pallas), is nearly as large as the Harfang. It also hunts during the day, and is sometimes seen in Germany. It is probably the Hybris or Ptynx of Aristotle.Ϯ  ...  Ϯ The Prince of Musignano places this remarkable bird in Syrnium. I have never seen a specimen, but - to judge from Mr. Gould's figure of it, in the Birds of Europe, - should be disposed to elevate it to the rank of a separate division (Ptynx); its large and complete ruff distinguishes it from Surnia, as its accipitrine form and lengthened tail do from Syrnium or Ulula" (Blyth 1840).   Var. Ptinx.
