Almost all items showed no differences by sex. 2. Mandibular angle observed from the upper side and lower side was nearly the same for both the beagles and the racoon dogs. 3. Between the beagles and the racoon dogs, there were differences in size and direction of the mandibular angle process and in the bakward protrusive degree of the condylar process, which a significant difference in the angles of the mandibular branch region. 4.
