﻿PLATE V. 



Pleistocene Bears (U. arctos). 



Mandible and Portions of Cranium. 



(Fig. 3 one half, the others two thirds natural size.) Each figure shows the 



palatal aspect. 

 Fig. 



1. Part of cranium from Crayford (No. M. 5041). Only the teeth of the right 



side and the neighbouring portion of the palate are figured. In the 

 British Museum this specimen is labelled U. spelxus, but as all the upper 

 premolars are represented, it seems better to attribute it to U. arctos. 



2. Part of the right maxilla and premaxilla from Manea Fen (No. 40405). 



3. Mandible from Burwell Fen. 



4. Anterior part of cranium from Manea Fen. 



5. Anterior part of cranium from Bourn, Lincolnshire. 



The Manea Fen cranium (fig. 4) and the Burwell Fen mandible (fig. 3) are 

 preserved in the Sedgwick Museum, Cambridge. The Bourn cranium (fig. 5) is 

 in the Museum of Practical Geology, Jermyn Street. The other specimens are in 

 the British Museum (Nat. Hist.), South Kensington. 



a. Mandibular condyle. 



b. Coronoid process.
