The insects, so far as they are known, including several 

 species of Donacea, are, like the plants and freshwater shells, 

 of living species. It may be remarked, however, that the 

 Scotch fir has been confined in historical times to the northern 

 parts of the British isles, and the spruce fir is nowhere in 

 digenous in Great Britain. The other plants are such as 

 might now be found in Norfolk, and many of them indicate 

 fenny or marshy ground. 



When we consider the familiar aspect of the flora, the 

 accompanying mammalia are certainly most extraordinary. 

 There are no less than two elephants, a rhinoceros and 

 hippopotamus, a large extinct beaver, and several large 

 estuarian and marine mammalia, such as the walrus, the 

 narwhal, and the whale. 



The following is a list of some of the species of which the 

 bones have been collected by Messrs. Gunn and King, and 

 named by Dr. Falconer and other geologists : 



Mammalia of the Forest and Lignite Beds below the Glacial 

 Drift of the Norfolk Cliffs. 



Elephas meridionalis. 

 Elephas primigenius var. 

 Elephas antiquus.
