QUATEENAET FAUNA OF GIBEALTAE. 85 



and perhaps a second may have existed until worn away by the usure of the tooth. 

 There is no distinct appearance of a groove on the inner aspect. 



The coronoid process is as much reclined as in the Common Cat, and projects back- 

 wards to a vertical line, which would touch the condyle and angular crochet. The 

 masseteric fossa is very deep, and its anterior margin much raised. 



2. The fragment of the second mandible, so far as it goes, precisely corresponds with 

 the former, except that it is scarcely stained with manganese, although it was imbedded 

 in the same kind of matrix. 



3. The entire humerus is 4"*3 long, the proximal end -QdX'lO, the distal 'bOX'Sd, 

 the least circumference 1""0, perimetral index -232. This bone has a very recent aspect, 

 and is obviously of much more recent age than the rest. 



4. The fragment of a humerus has an ancient look, but corresponds in all respects 

 with the above. 



5. The portion of ulna, from the condition of the bone, would seem to belong to the 

 opposite side of the same individual as No. 4 ; whilst 



6. The tibia and metatarsals have the more recent aspect of the entire humerus. 

 There can be no doubt, however, that all these bones belong to the same species. 



Of the numerous existing species of Cats smaller than the Lynx, and varying in siee 

 from the Serval to F. maniculata, and in which the upper camassial tooth never exceeds 

 0"-5 or 0"-55, and the lower 0"-4 or 0"-45 in length, the only ones with which it appears 

 worth while to compare the Gibraltar form are : —
