Mammals, Extinct. — Probably not one of the species occurring 

 in the Forest Bed series, or in the older deposits mentioned in this 

 paper, is identical with any form now existing. The references to 

 recent species made by earlier writers on the subject were based 

 either upon imperfect material or misconceptions. Each form as it 

 becomes known by proper material proves to be extinct ; but in the 

 case of several of the species the material is still only sufficient to 

 permit of a generic determination. This was the opinion of 

 Dr. Forsyth Major, expressed about 1908 in the Geological 

 Magazine, and, after many years' work on Forest Bed remains, it 

 has become my opinion also. (M. A. C. H.) 



Reference should be made to Kennard, " The Pleistocene 

 Succession in England," Proc. Prehist. Soc. East Anglia, vol. ii, 

 part ii, 1916, and to the papers of Hinton and Forsyth Major cited 

 therein. 



Derived Specimens. — The faunal lists are complicated by the 

 presence of derived specimens washed into these fiuviatile formations 

 from underlying beds, especially from such ancient beds as the 

 Eocene London Clay, e.g. Hyracotherimn, Coryjihodon ; also possibly 

 from Pliocene beds, e.g. Mastodon longirostris, Rhinoceros 

 schleiermacheri. These certainly derived specimens and species are 

 also placed in square brackets [] to indicate that they are of older 

 age or are species wrongly referred. There is, for example, no 

 possibility that the Lower Pliocene species Mastodon longirostris 

 Kaup occurs in the Red Crag. 



These fauna! lists are, therefore, of a preliminary character, but 

 it is hoped that they will serve a useful purpose in the advance of 

 our knowledge of Pliocene and Pleistocene correlation, on which 

 the author has been engaged for many years.
