QUATERNAET FAUKA OP GIBEALTAE. 81 



differs from that of the existing Leopard, if we may judge from the figure, in the 

 excavation of the anterior part of the anterior cusp on the inner face, on which aspect, in 

 the Gibraltar specimen and the existing Panther, the surface is uniformly convex. 



In conclusion, it may be remarked that the size of the lower true molar in the 

 Bleadon-Hill Leopard, ■8X'4, exactly corresponds with that of the same tooth in the 

 Gibraltar specimen ; and this is a character in which these two specimens appear to 

 exceed any recent Leopard with which I have had an opportunity of making comparison. 

 In the figure of the lower jaw of Felis 2}a)'dus, however, given by M. de Blainville \ 

 the antero-posterior length of the tooth appears to be the same as in the two fossil 

 instances. 



I would observe, however, that, although in the Gibraltar Leopard the lower car- 

 nassial is so unusually long, the penultimate is of exactly the same length, and the next 

 but very slightly longer.

The true Lynxes (excluding the Caracal) constitute a peculiar well-defined subgeneric 

 group of Cats, characterized, so far as external features are concerned, by long legs, short 

 tails, and usually tufted ears, to which, as more intrinsic characters, may be added the 

 almost invariable absence at all ages of the foremost small upper premolar ( pm. 2) , 

 which is generally present in almost all other felines — and, according to Keyserling and 

 Blasius 2, by the circumstance that the nasals are separated from the maxillaries by the 

 intervention of the descending process of the frontal meeting the premaxillary) 

 Blasius adds, as another character of the Lynx Cats, that the lower carnassial (m. I), 

 is tricuspid. But in this he is manifestly in error, since that condition obtains only in 

 one of the four or five species constituting the group ; it is in fact confined, so far as 

 my observation extends, exclusively to the northern Lynx of Europe and Asia. 



Of the group thus characterized, several European forms have been described under 

 different specific names ; but at present I believe zoologists are tolerably unanimous in 

 considering that there are in the Old World only two specifically distinct forms. The 

 larger, best-known, and more widely distributed of these is Felts lynx, Linnseus and 

 Pallas, under which are included : — 



F. cervaria, Temminck, Nilsson, Cuv. 



F. lupulina, Thunb. 



F. lyncula, virgata, Nilss. 



F. lynx, Schreber, Temminck, Bechst., Keyserling and Blasius, Blasius, Schinz, 

 Blainville, &c.

^ Dr. Gray made the same observation, and applies it to " all the species of Lynx both from the Eastern 

 and Western Hemispheres," apparently unaware that he had been anticipated by Keyserling and Blasius.
