is flat or only slightly concave from side to side, but on the middle of the upper 
surface of the muzzle there is a short depression on each side of the nasals. The 
ridges of the maxillse from the maxillary-malar suture are more rounded and swollen,

The lateral postsymphysial pit is only indicated by a shallow concavity, scarcely
