260 J. Wilfrid Jackson — Lynx in Wales and Derby. 



latter it is difficult to decide ; the bone agrees with a corresponding 

 bone of the brown bear {Ursus arctos) in the Manchester Museum, and 

 in all probability belongs to that species. 



With the exception of the lynx and wolf, all the other animals are 

 well represented by several parts of their skeletons. Most of these, ■ 

 however, appear to have been met with in association with the human 

 remains found in the cave, and without doubt belong to a later period. 



The lynx is represented by the right ramus of the lower jaw 

 containing only the carnassial tooth, the others being represented by 

 their sockets. The ramus is almost complete, wanting only the angle 

 and part of the articular condyle ; the alveolar border is more curved 

 than the inferior, and the jaw is thickened anteriorly. There is 

 a small convexity of the inferior border owing to the ramal process 

 being slightly developed. 



Compared with the examples from Pleasley and Cales Dale, the 

 Gop jaw is somewhat smaller, but appears to belong to the same 

 species, viz. the Northern Lynx, Felis lynx {horealis). 



The following table of measurements (in inches and tenths) shows 

 the correspondence of the Gop jaw with those of Cales Dale, Pleasley, 

 and a Northern Lynx in the British Museum (E.M. 1230a), these last 

 three being taken from Mr. W. Storrs Fox's paper (op. cit., p. 68), 

 and Professor Dawkins' British Pleistocene Mammalia. 



Unfortunately the geological age of the various remains in this 

 cave cannot be determined with absolute accuracy, as, owing to the 

 excavations of badgers, foxes, etc., it was impossible to be sure of the 

 relative positions of some of the bones. The discovery, therefore, of 

 the lynx throws no fresh light upon the question of the period at 

 which this animal inliabited this country. That it lived side by side 

 with the other fierce carnivores seems the most reasonable suggestion, 

 for, as pointed out by Professor Dawkins {Brit. Pleid. Mam.), the
