n 



Incisor teeth ^ , canines large, acuminate ; molars uniformly- 

 enamelled, with acute crown uneven, one or more of the hinder 

 teeth tuberculate. Toes mostly cloven. 



To this division belong the species which, more than the rest 

 of the /erce, deserve the name of carnivores or beasts of prey. 

 Although some {Lutra) have swimming membrane between the 

 toes, all are formed for running, a kind of movement for which the 

 animals of the preceding division are not adapted. 



One of the molar teeth, which exceeds the rest in size, is fur- 

 nished with a sharp cixtting edge [dens lacerans, dens sectorius, la 

 carnassiere F. Cuvier) ; the smaller molars placed in front of these 

 are named false molars {fausses miolaires), whilst the hindmost 

 molars that have flat crowns are named tuberculate molar teeth; 

 see F. Cuvier in the Aim. du Mus. x. pp. 104 — 129, and in his 

 work, so frequently referred to, on the teeth of mammals. Owen 

 has given a different division of the teeth, which is more physiolo- 

 gical. He, as has already been stated, distinguishes the molar teeth 

 OS, premolars and true molars; the first are successional, the last not. 

 The typical niimber of the premolars is 4 in both jaws on each 

 side, that of the true molars 3. In the genus Felis the premolars 

 are 3 above and 2 below, with only one true molar above and 

 below: namely the small tuberculate molar of the upper jaw, and 

 the laniary or carnassial molar of the lower jaw. See Ann. des 8c. 

 nat, 3e Serie, iii. 1845, Zool. p. 116 — 128, and Todd's Cyclop, iv. 

 pp. 898—935.
