Rh :Hippopotamus (major?).
 * Sus. 
 * Equus (fossilis?). 
 * Bos.
 * Cervus Capreolus? and other species of Cervus.
 * Arvicola amphibia.
 * Castor trogontherium.
 * Castor europæus.
 * Narwhal, walrus, and large whale, or Balænoptera?

Mr. Gunn informs me that two large whales were found in the fluvio-marine beds at Bacton, and that the vertebræ of one of them, shown to Professor Owen, were said by him to imply that the animal was sixty feet long. A narwhal's tusk was discovered by Mr. King near Cromer, and the remains of a walrus. No less than three species of elephant, as determined by Dr. Falconer, have been obtained from the strata 3 and 3', of which, according to Mr. King, E. meridionalis is the most common, the mammoth next in abundance, and the third, E. antiquus, comparatively rare.

The freshwater shells accompanying the fossil quadrupeds, above enumerated, are such as now inhabit rivers and ponds in England; but among them, as at Runton, between the 'forest bed' and the glacial deposits, a remarkable variety of the Cyclas amnica occurs, fig. 28, p. 218, identical with that which accompanies the Elephas antiquus at Ilford and Grays in the valley of the Thames.

All the freshwater shells of the beds intervening between the forest-bed No. 3, and the glacial formation 4, fig. 27, are of recent species. As to the small number of marine shells occurring in the same fluvio-marine series, I have seen none which belonged to extinct species, although one or two have been cited by authors. I am in doubt, therefore, whether to class the forest bed and overlying strata as
