The third molar has not erupted and its roots are not yet formed. Cement Enamel Dentine distinct neck. The convex labial surface has an extensive covering of enamel, but the latter covers only a small marginal area on the lingual surface. The second are much shorter and are only slightly curved; they have a short flattened cro'svn and a rounded root. The third incisors are much smaller, are flattened laterally, and have three small eminences on the crown. The lower incisors are almost horizontal and are convergent and close together. The first and second are about ecjual in size, are rod-like, very slightly curved, and deeply implanted in the jaw. The labial surface is slightly convex, the lingual concave and marked near its extremity by a ridge. The third incisor is much shorter and is some- what flattened; it has a short narrow crown and a distinct neck. The canine teeth or tusks of the male are greatly de- veloped and project out of the mouth. The upper canine of the boar may be three or four inches (ca. 8 to 10 cm.) long. The crown is conical and is curved some- what backward and outward; the embedded part is curved and has a large pulp.
