fiat on the inner side of the blade, and has a horizontal sinuous 

 edge : the internal basal tubercle (fig. 2, p 4) is developed from 

 the interspace between the first and second lobes of the blade : this 

 is relatively smaller than in the Hyeena, and almost obsolete in the 

 Hunting-Leopard {Felis jubata) and in a small allied extinct Feline 

 animal of Brazil, which Dr. Lund, adopting the sub- generic name 

 applied by Wagler to the Hunting-Leopard, calls Cynailurus mi- 

 nutus{l). In all the Felida; the upper sectorial has three fangs, 

 the two anterior ones being on the same transverse line. The small 

 tubercular true molar (fig. 1 & 2, m 1) has a transversely extended 

 elliptical or sub-trihedral crown. 



The first lower premolar (marked p 3 as being the analogue 

 of the third in the Dog) is implanted by two fangs which support 

 a middle compressed cone and an anterior and posterior basal tu- 

 bercle ; its crown passing behind the first upper premolar shows it 

 to answer to the second above. The second premolar below {p 4) 

 is larger and has two posterior tubercles ; its crown fits into the space 

 between the second and the third or sectorial premolar above, oppos- 

 ing the anterior lobe of that tooth.; The last molar below [m. 1) 

 is the sectorial tooth, the crown of which consists exclusively of the 

 blade ; this is divided into two equal, compressed, pointed lobes, 

 with straight margins, very sharp except the anterior one of the first 

 lobe ; the contiguous margins of the two lobes meet at a right angle, 

 from which a vertical fissure extends nearly half way down the crown. 

 The outer surface of the crown presents an equable convexity from 

 before backwards ; the inner side is deeply excavated between the 

 iobes (tig. 3). A transverse notch near the base of the posterior 

 margin of this tooth indicates the rudiment of the talon or tubercle 

 which distinguishes the corresponding tooth of the Hyaena ; the in- 

 dication being strongest in the aberrant species of Felis, as the Lynx 

 and Hunting-Leopard (2). Although the lobes of the crown of the 

 lower sectorial tooth are equal, the anterior fang is much larger

(2) M. de Blainville, by whom many interesting varieties manifested by specimens in the 

 Cuvierian collection have been carefully noted, figures one, from the Canada Lynx, in 

 Avhich a small tubercular luular exists behind the lower sectorial tooth; thus presenting 

 an analogy to the Stoat and other Miistelidce. ' Osteographie dc Fehs,' pi. 14, p. 57.
