124 Mr. R. 1. Pocock on the 



second and tliird digits are provided with inner lobes to 

 the claw-sheaths, that of the third being larger than that 

 of the second. There is, however, no distinct inner lobe to 

 the claw-sheaths of the fonrth and fifth digits. The webs 

 are moderately Avell developed. In the hind foot the digits 

 are witliout inner lobes to the claw-sheaths, or, at all events, 

 these lobes are so small as to be negligible (fig. 5, A, B). 



F. ocreata has feet almost precisely like those of 

 F. sylvestris. 



Felis serval. — The feet in a general way resemble tolerably 

 closely those of F. sylvestris, except that the sheaths of the 

 claws are relatively a little larger, the inner lobe of the third 

 digit in the specimen examined being exceptionally well 

 developed and larger than the outer lobe. The carpal pad 

 also is relatively larger (fig. 5, C, D). 



Felis caracal. — The fore foot is tolerably similar to that 

 of F. sylvestris, but the digits are more separable, the claw- 

 sheaths somewhat larger, and the webs, particularly those 

 joining the second and third and the fourth and fifth digits, 

 shallower and more emarginate. In the hind foot the third 

 digit carries a well-developed inner lobe to the claw-sheath, 

 the plantar pad is longer as compared with its width than in 

 F. sylvestris, and the webs are much shallower, especially 

 that connecting the third and fourth digits. The digital 

 pads, also both of the fore and hind foot, are more pointed 

 distally than in F. sylvestris and F. serval (fig. 6, A, B). 



As I have already remarked (Ann. & Mag. Nat. Hist. (8) 

 xviii. p. 429, 1916), the hind feet of F. caracal recall those 

 of Acinonyx jubatus in the emargination of the webs. 



Felis lynx isabellimis (fig. 7, C, D). — The feet differ in 

 some interesting particulars from those of F. caracal. In 

 the fore foot the plantar pad, owing to the encroachment 

 of the surrounding hair, is shorter as compared with its 

 width ; the webs are deeper and hardly differ in develop- 

 ment from those of F. sylvestris and F. serval ; the claw- 

 sheaths are exceedingly well developed on the second and 

 third digits, the inner lobe of the third being approximately 

 as large, relatively, as in F. serval, and there is a distinct 

 inner lobe on the fourth and fifth digits, that of the fourth 

 being large, that of the fifth smaller but distinct. In the 

 hind foot the plantar pad is longer for its width than in 

 the fore foot, but not so long as in F. caracal. The webs 

 are rather more emai'ginate than in F. sylvestris and 

 F. serval^ but not nearly so shallow as in F. caracal. As in 

 the fore foot the claw-sheaths are complete on all the digits,
