MERISTIC VARIATION. 



[part I. 



288. Specimen having a small tooth internal to the middle of the lower 

 [Iside] carnassial (m l ): the extra tooth was here divided into two cusps 

 so that it was a copy of the carnassial. Hexsel, I. c.

Fig. 49. Plan of teeth in upper jaw of Cat, No. 287. The two teeth marked 

 with crosses are separately shewn, that on the right being the external. 



289. Specimen having a tooth like the last, but not so distinctly divided 

 into two cusps, internal to posterior end of lower carnassial [?side].

Supernumerary Molars. 



Cases like the last cannot be clearly separated from cases of 

 true extra molars in series, such as the following. 



It is remarkable that no case of supernumerary upper molar in 

 series seems to be known in Felidas. In the Tiger and other 

 species the upper molar is sometimes single- and sometimes 

 double-rooted. 

 *290. P- fontanieri : a species nearly allied to the Leopard (F. 

 pardus), inhabiting the Kiu-Kiang, a geographically isolated region 

 of N. China. Only two skulls are known, and each of them pre- 

 sents an abnormality in dentition (see No. 284). Skull having 

 supernumerary tubercular tooth in series («j2) behind the left 

 lower molar (m 1 ). B. M., 1490, a. 



291. r - pardalis: ^ on left side. Hensel, Morph. Jahrb., 1879, v, p. 541. 

 F. tigrina : tubercular JJp on left side. Schlegel, P. Z. S., 1866, p. 419. F. lynx: 

 ditto [? side]. Magitot, Anom. syst. dent., p. 103. F. domestica : "supernumerary 

 permanent molar in lower jaw" [no particulars]. Wtman, J., Proc. Boston N. H. S., 

 v, p. 160. F. pardus : doubtful indication that a left m* has been present. C. M., 

 933, F. 



Absent Molar. 



F. leo : in^ absent on both sides, and there is no space for it behind the upper 

 carnassials. B. M., 3043. The only case seen in all Felidas examined. F. domes- 

 tica : ml absent [? both sides]. Hensel, I. c, p. 541.
