CAUNIYOBA. 



The teeth in front of it are more oi' less sharp, pointed, and com- 

 pressed ; those behind are broad and tiiberculaled. The sectorial 

 in the upper jaw is the hindmost jiremolar, acd consists of a more 

 or less compressed bicuspid or Iricuspid crown on tworoois and an 

 inner lobe supported by a third root. In the Ur^Ulcr, in which the 

 sectorial teeth are ill-developed, the inner lobe and root are want- 

 ing. The lower sectorial is the first true molar, and consists of two 

 roots supjwrting a bilobed compressed crovAn, with, in general, a 

 keel and an inner tubercle ; both of which, however, are wanting 

 or rudimentary in the most s]:»ecialized Caruivora, as the Felklci'.

Suborder FISSIFUDIA. 



As already mentioned, the limits of this suborder (or order 

 according to some \\riters) are generally admitted ; but the sub- 

 division into sections and familii's is ditlicidt, owing to the com- 

 plicated relationships between the different genera. The majority 

 live entirely iipon animal food ; but a few, like the bears, feed on 

 a mixed diet, of which vegetables form a portion. A coiisiderable 

 nundi(>r, as the cats and dogs, walk on their toes, and areknov\n as 

 Digitigrade, whilst others, for instance the bears, rest upon their 

 ])alms {palma) and soles (phinta) and are distinguished as Planti- 

 grade; ; a s()mev\hat intermediate mode of jirogression, f(miul in the 

 weasels, otlers, and badgers, being termed Semi])]aiitigrade. This 

 distinction has been extensively employed in classiiication, but is
