I.—Note on a Devonian Cælacanth Fish

Abstract
Students of Palæozoic fishes are indebted to Professor A. von Koenen, of Gottingen, for two interesting memoirs on the fragmentary fish-remains of the North German Devonian formations. Owing to their incomplete character, however, the Professor is only able to suggest a provisional interpretation of most of the specimens, and the determination of their true nature must be left for future discoveries.
