VULPES VULGARIS. 135 



varieties of Dog differ, besides, in their superior size ; 

 and the resemblance of the Fox to the Wolf and the 

 Jackall, in the opinion of Mr. Bell,* is scarcely sufficient 

 even to constitute it a species of the same generic group. 



The skull of the Fox is narrower, and contracts more 

 rapidly anterior to the orbits ; the forehead is more con- 

 tracted and flatter than in the Wolf or Jackall. The 

 exoccipital mastoid process is longer, the orbito-frontal 

 process is shorter, the upper margin of the squamo-tem- 

 poral bone is straighter and the zygomatic arch is broader 

 and more open than in the Wolf or Dog. 



The scapula indicates an approach to the Feline tribe, 

 in its longer coronoid process and its bifid acromion. The 

 clavicle is more developed. The bones of the extremities, 

 especially of the feet, are more slender than in the Jackall, 

 and still more so than in the Dog or Wolf. In regard to 

 the teeth, the canines (fig. 52) are relatively 

 more slender and more curved than in the 

 Wolf, Dog, or Jackall, and the upper true or 

 tubercular molars, like those in the Jackall, are 

 relatively to the carnassial tooth, larger than in 

 the Wolf and Dog. 



With these grounds for determining the 

 small fossils of the genus Canis, one may un- 

 hesitatingly concur with Mr. Mac Enery, in 

 referring to the Fox the right ramus of the oreston 

 lower jaw discovered by him in Kent's Hole, so 

 superficially situated, indeed, as might justify the suspicion 

 of its recent introduction. 



The remains of the Fox from the same cavern, now in 

 the British Museum, present, however, precisely the same 

 fossilized state as the bones of the Spelaean Bear and
