In this genus the tooth, p 4, above chiefly playsupon the tooth, m l, below, which has a similar sectorial or car-nassial modification of form; they fit, indeed, almost as Cuvierdescribes, like the blades of a pair of scissors. The two teeth inadvance of the carnassial in the upper jaw, p 3, p 2, in like mannerare opposed to the same number of fausses molaires in theunder jaw, and the canine, c, above plays upon the canine below: VOL.
