up to the distal ends of the digital pads^ as iu F. nebiilosa. 

 Tiie claw-sheaths also are well developed, with distinct inner 

 lobe upon the second, third, and fourth digits; bnt this lobe 

 is sufheiently small to be negligible npon the fifth digit. 

 In the hind foot the webs are also well developed, although 

 shallcnver than on the fore foot. The inner lobe of the elaw- 

 slieath is negligible npon the second and fifth, bnt ■well 

 developed on the third and distinct though small upon the 

 fourth digit. 



F. pard/ilia has feet similar to those of F. loiedii (Ann. & 

 Mag. Nat. Hist. (6) xviii. p. 4^8, fig. 5, A, 1916). 



It is interesting to notice that the feet of F. wiedii and 

 F. pardalis differ I'ather markedly from those of F. genjfroyi, 

 F. sali/iannn, and F. Jaguarondi, and also from those of 

 F. concolo}\ though to a slightly less extent, iu the develop- 

 ment of the webs and of the claw-sheaths. 



F. conculor (fig. 11, A, B, C). — In an example three 

 months old the feet are shorter and broader than in 

 F. yeojfroyi, and provided with larger pads and better 

 developed claw-sheaths. Nevertheless, the webs are de- 

 veloped to approximately the same extent, and the inner 

 lobe of tJie claw-sheaths is small upon the second and 

 third digits and negligible upon the fourth and fifth of the 

 fore foot, and also negligible npon the second, fourth, and 

 fifth of the hind foot. In neither foot do the sheaths encase 

 the claws almost to the tip, and, in the extent to which the 

 claws when retracted are exposed, the feet approximately 

 resemble those of F. fjeoffroyi, jaguarondi, viverrina, and 

 sylvestris, and do not conform to the type of foot of 

 Panther a ffig. 12). 



Genus Panthera, Okcn, 



In the species of the genus Panthera (fig. 12) examined, 

 TidLxaoXy, P. pardus, onca, iigris, and leo, the feet are very 

 much alike. They are short, broad, compact, and difficult 

 to spread. The plantar and digital pads are large and the 

 sheaths are well developed, both npon the outer and 

 the inner side of the claw, and almost conceal the tips 

 of tlie claws when retracted. In the fore foot the carpal pad 

 usually has a widely rounded apex, and the webs extend almost 

 up to the tips of the digital pads, at least on the admedian 

 side, and show only a shallow emargination when the digits 

 are stretched. In the hind foot the webs are less extensive 

 and more emar-inate.
