THE VERTEBRATA 



OF THE 



PLIOCENE DEPOSITS 



OF 



BRITAIN. 



INTRODUCTION. 



An endeavour is made in the present Memoir to give some 

 account of every species of Vertebrate animal which has been 

 recorded from, or is now known to occur in, the Pliocene strata of 

 Great Britain, and the work will form a companion volume to the 

 " Vertebrata of the Forest Bed Series of Norfolk and SuflFolk," 

 which treats of the Vertebrate remains from that important section 

 of the Pliocene deposits of East Anglia. In order to make the 

 present volume complete in itself, all the species included in the 

 " Forest Bed Memoir " are briefly alluded to, and such additional 

 Information as may have been obtained regarding; them is here 

 recorded. Besides this, several species, new to the "Forest 

 Bed," have more recently been brought to liglit, and these also 

 are included. 



No illustrations of the Forest-bed Cervidae were given in the 

 earlier Memoir, but it has been decided to introduce several of 

 them here, and they will be found on Plate IV., all the figures 

 being one-fourth the natural size of the specimens. 



For the execution of the lithographic plates illustrating this 

 Memoir, I am under obligation to Mr. W. M. Redaway, who has 

 spared no pains to make the drawings accurate, and, with few 

 exceptions, they have been drawn directly from the specimens. 



Fragmentary as are the vertebrate remains from the Forest- 

 bed, those from the Crags are even more unsatisfactory for deter- 

 mination, being for the most part isolated teeth and pieces of 

 bones, much rolled and water-worn. Nevertheless, some of these 

 teeth are in a remarkable state of preservation, being very hard, 

 of a reddish brown colour, and with a peculiar lustrous surface, 

 which makes them elegant objects in the cabinet.
