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

 species of Donacea, are, like the plants and fresh-water 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 hippo- 

 potamus, 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 heloio the Glacial 

 Drift of the Norfolk Cliffs. 



Elephas meridionalis. 

 Elephas primigcnius var. 

 Elephas antiquiis. 

 Mhinoceros etruscus.
