MR. W. STOnUS FOX OX BONES 



[Jan. IG, 



vei-y iimeli worn down. When this bone was fonnd the canine 

 Avas not in situ, but a tooth has been placed in the socket, into 

 which it exactly fitted. The third premolar is missing altogether ; 

 and, as the bone has entirely closed over the socket, this tooth 

 must either have been lost some time befoi'e the death of the 

 animal, or it could never have existed at all. The fourth premolar, 

 when found, was separate from the jaw, but the molar was in 

 position in the bone. 



Taking into consideiation the shrinkage caused by the absence 

 of the third premolar, this ramus closely corresponds in general 

 outlines with the Pleasley one described by Professor Dawkins. 

 The following table of measurements, the last tv/o columns of 

 which are taken from ' British Pleistocene Mammalia,' shows this 

 correspondence. The measurements thioughout are given in 

 inches and tenths. 



The total length of the canine now fixed in the jaw could not 

 be measured ; and as the tip is broken ofl^, the oi'iginal height of 

 the crown must remain uncertain. But the two odd Cales Dale 

 canines are respectively in length : 1'65 ins. and 1'9 ins., whereas 

 the Pleasely specimen is 1^85 ins. ; and the height of the crowns 

 of these two Cales ])ale teeth is exactly the same as that of the 

 i-ight lower ramus of Felis lynx {horeaUs) in the British Museum, 

 namely, "8 inch, as compared with ^75 inch in the Pleasley 

 animal.

The measurements of the upper carnassial (text-fig. 26 A) and 

 of the incisors show that there is very little difierence between 

 the Cales Dale teeth and those of F. lynx {horealis). 



* As Pm. 3 is lacking in the Cales Dale specimen, the measurement is taken hehind 

 the socket of the canine. This absence of Pm. 3 accounts for the relatively small 

 circumference here.
