to tlio loss of ilio post('rior yiortion, the inner wall of the dental canal has been crushed 
in, and tlie anterior alveolus is incomplete. The symphvsial surface extends 
back as far as the liinder border of p)n. 2. The sino'le alveoli of the incisors, the canine, 
and the first premolar are empty; they are separated from one another and from pni. 2 
by almost equal int(>rvals of about 2'i cm. Pin. 2 is a two-rooted tooth, comywessed 
and sliarp-edeed, with two accessory denticles on its posterior border ; pni. 3 is 
represented by its two alveoli only ; 2 >m. 4 is a large two-rooted tooth apparently 
having three accessory denticles on both its anterior and posterior borders. The molars 
are smaller teelh closely crowded together. In all, the anterior border is nearly 
verlical and without denticulations, while the ])()sterior border has two or perhaps three 
accessory denticles in )n. 1 and /». 2, and at least three in ni. 3. The crowns of all the
