MAMMALS CANIDAE VULPES LITTORALIS.

off rapidly to a point. The intermaxillary is applied along their anterior half, the frontal along 

 the posterior third of the outer edge. The temporal ridges are sufficiently distinct. The 

 anterior portion of the frontal bone is considerably swollen above the eyes, these elevations 

 separated by a deep depression along the median line and ceasing a little posterior to the centre 

 of the orbit. The lateral profile shows a depression in the upper outline of the skull at this 

 point. 



An appreciable peculiarity of this species is seen in the anterior base of the zygoma. The 

 suture of this shows no bifurcation of the malar at all, but merely a broad emargination, with 

 irregular or zig-zag outline. The bone is produced forwards, inwards, and upwards as a narrow 

 process, which occupies not one-third the space between the edge of the orbit and the ante-orbital 

 foramen. In the gray fox the space thus occupied is nearly or quite half this distance, sometimes 

 a little more.
