the first instance the newest (4th) edition of Brehm’s Tierleben, then Jaeger, Dr. G., Deutschlands Tierwelt nach ihren Standorten eingeteilt (Stuttgart 1874); Schäff, Ernst, Dr., Die wildlebenden Säugetiere Deutschlands (Neudamm 1911; J. Neumann); Voigt, A., Prof. Dr., Deutsches Vogelleben, Teubner, Leipz. 1808 (Nat.- u. Geisteswelt 221); Zimmer, Carl, Dr., Anleitung zur Beobachtung der Vogelwelt, Quelle & Meyer, Leipzig 1910 (Wissensch. u. Bild. 86); Floericke, Kurt, Dr., Deutsches Vogelbuch, Stuttgart 1907, Kosmos. For the identification of fish, the most excellent aid proved to be No. 12 of the Publications de circonstance du Conseil permanent international pour l'exploration de la mer: Catalogue des poissons du Nord de l'Europe, 2nd ed. Hosta Fils, Copenhagen 1914; Bröhmer, P. Dr., Fauna von Deutschland, Quelle & Meyer, Leipzig 1914—almost exclusively ecologically oriented works, but with a writer who knows no system and often offers only meager life-historical hints, little can be accomplished with the best systematic works.
Falling more into the linguistic-historical direction are: Suolahti, Hugo, Die deutschen Vogelnamen, Strasbourg, Trübner 1909; Keller, Otto, Tiere des klassischen Altertums in kulturgeschichtlicher Beziehung, Innsbruck, Wagner 1887 and Die antike Tierwelt, Leipzig, W. Engelmann 1909/13; Steier, August, Dr., Aristoteles und Plinius, Würzburg, Rabitsch 1913 (collection of three special reprints from the Zoolog. Annalen, Vols. IV and V), and the same author’s program of the Royal Old Gymnasium at Würzburg for 1913: Der Tierbestand in der Naturgeschichte des Plinius.
Furthermore, a number of valuable essays by Dr. B. Szalay-Hermannstadt appeared in the Zoologische Annalen (edited by Privy Council R. Dr. Max Braun-Würzburg), which deal mainly with the history of wild cattle and are named individually under urus and vesontes in the index, as well as a small publication by Prof. Dr. Seb. Killermann-Regensburg: Das Tierbuch des Petrus Kandidus, which in the text offers the views of a scholar from the year 1460, and in the beautiful pictures, which Killermann mostly interpreted well, those of a 16th-century painter. Killermann’s own identifications are, of course, to be used with great caution; even more so regarding his "Vogelkunde des Albertus Magnus" (Regensburg 1910), since he, not sufficiently distinguishing between the intellectual property of Aristotle and Albertus, often mixes up Greek and German fauna. He does not speak of Thomas at all.
In conclusion, the old Gessner should be remembered with honor (I had a Latin edition from Frankfurt by Henricus Lavrentinus from 1620 from the Burghausen Gymnasium library), who still gives good advice in such matters. I have dealt with the Book of Snakes (25) very briefly: not a dozen animals are identifiable; what
