J. Wilfrid Jackson — Lynx in Wales and Derby. 261 



carnivore in question must have crossed over into Britain when this 

 country formed part of the mainland of Europe ; for it is impossible 

 to suppose that it could have invaded our Island from France or 

 Germany during prehistoric times. 



But what we should like to know more about is the period of its 

 extinction in Britain. Like the wild cat it may have lingered in the 

 wilder districts much later, say, than the lion, almost down to the 

 historic period, for it appears to- have only recently become extinct in 

 Prance, a specimen being killed in the Haute Loire in the year 1822, 

 while a second was killed in Wiirttemburg in 1 846. 



Li conclusion, I wish to thank Dr. C. W. Andrews for kindly 

 confirming the identification of the lynx and several other forms. 

 I am also indebted to Mr. J. H. Morris for allowing me to describe 

 this specimen. 



Fig. 1. Eight ramus of the lower jaw of Lynx. Gop Cave, near Prestatyn, 

 North Wales. Nat. size. m. 1 = true molar ; p.m. 4 = socket for fourth 

 premolar ; p.m. 3 = socket for third premolar ; c. = socket for canine ; 

 i. = socket for third incisor. 



Since writing the above note I have discovered a fragmentary right 

 superior maxilla of a lynx in the Manchester Museum collections, the 

 specimen being labelled as coming from Cales Dale, Derbyshire. It 

 appears to have been in the Museum for some years and may possibly 

 have been obtained during one of the explorations of Cales Dale Cave 

 previous to that of Mr. Storrs Fox in 1897. 



The specimen is of some interest on account of the entire absence 

 of the anterior premolar tubercular tooth, with no trace of any 

 alveolus. This feature appears to be one of the characters constituting 

 MM. Croizet et Jobert's species, Felis hrevirostris, remains of which 

 were found in one of the Cresswell Crag caves (Robin Hood) and 

 described by Dr. B. Laing in the Beport of the British Association for 

 1889 (pp. 582-4). 



The Cales Dale specimen being so fragmentary does not lend itself 

 to detailed measurements, but one or two can be given. The total 

 length of the canine is 1-75 inches, while the height of the crown is 

 •75 in. ; between the canine and p.m. 3 there is a diastema of '35 in.,
