ICHTHYOLOGY,
At the Read of this year’s Report I place a Memoir byJ. Muller, which affords expositions of the highest import-ance with regard to the systematic arrangement of theFishes: Ueber den Bau und die Grenzen der Ganoidenund iiber das natiirliche System der Fische (On theStructure and Limits of the Ganoidei, and on the NaturalSystem of the Fishes) in the Reports of the Berlin Academy,1844', p. 416, and further detailed in these Archiv. (1845,p. 91.) Since the system here proposed rests upon such acertain base that it will undoubtedly be universally recog-nised, I shall in what follows arrange my Report accordingto it.
Of importance for the knowledge of Fishes is a workedited by Lichtenstein : J. Forsteri, descriptiones animaliumin itinere ad maris australis terras, per annos 1772 bis1774 suscepto, observatorum; Berolini, 1844. 8. Forster’sdescriptions have hitherto been before the public only inBloch’s Systema ed. Schneider, and in fact not in a completeform. They appear in this work complete, and with theaddition of those names which have been given to the Fishin later times, particularly in Schneider’s edition of Bloch,and in Cuvier Valenciennes.
