I can, therefore, only express my thanks toHerr Monke for the valuable work he has accomplished with thevery fragmentary material at his command. I have also to tendermy best thanks to the Kev. Samuel Couling for entrusting mewith all the specimens he was able to obtain and presenting themto the Geological Department of the British Museum (NaturalHistory), Cromwell Eoad. EXPLANATION OF PLATE XIII. The photo reproduction of fossil remains shown on our plate has been taken froma portion of a large slab procured by the Rev. Samuel Couling, , of Kiao-chow,North China, and in age considered by Herr H. Monke to
