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 (jig. 52) are relatively

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 
Canine, Fox.

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 Spelean Bear and
