Elementary text-book of zoology (1884) Elementary text-book of zoology elementarytextbo0201clau Year: 1884 CAENIVORA. 325 size, and by their genuine carnivorus dentition (rig. G98). The denti- tion contains all three kinds of teeth : above and below six small incisors with single roots, and at their sides ;i long, conical pointed canine tooth ; then a number of grinders, which arc distinguished into pra?niolars ('/. ,sy>///-/7), a carnassial tooth (if. sectoring), and molars (d. molar*:*). \Ve never find prismatic grinders with needle- shaped points on the crown, as in the Insectivorct. The compressed and sharp-edged pnemolars are the least developed ; the characteristic carnassial teeth are distinguished by the size of their cutting, usually two-or three-toothed crown, and often by the possession of a posterior bluntly-tuberculatecl lobe (upper carnassial tooth). The lower car- nassial tooth is always the first molar, while the upper is the last piwmolar. The true molars have several roots ; they possess bluntly - tuberculated crowns, and vary in size and number. The external form of the skull and dentition, the high temporal crest of the skull for the attachment of the large temporal muscle, and the marked curvature of the zygo- matic arch for the passage of the same, the transverse articular cavity (glenoid cavity) of the temporal bone, and the cylindrical FIG. . articular head of the lower jaw, which restricts the motion of the jaw to the vertical plane and excludes lateral movements,—are characters which are common to all the Carnivora, and coincide with the form of the dentition. The limbs end with four or five freely-movable digits, which are armed with strong cutting claws (accessory to the dental apparatus), and in the front limbs are also used for seizing the prey. Only a few Carnivora, as the Bears, are true plantigrades resting the whole sole of the foot on the ground; others, as the Viverridce, only place the anterior part of the sole (the digits
