A fifth area, small, varying in elliptical pattern, at posterior symphyseal bevel opposite front of largest oral dental area, and followed by a prominent ridge which is convex with about two rather prominent longitudinal ridges, and curving back forms edge of mandible ramus posteriorly inside. Upper maxillaries a little more than twice as long as wide, and their depth a little less. Form generally depressed. Upper sur- face of each with a deep wide gutter extending forward about two- thirds its length and ending in a deep pit, anterior to which area is. Fig. 71.—Edaphodon mirificits Leidy. (Type of Ischyodus gaskillii Cope, from Hussakof.) flat and horizontal. Sides of upper maxillaries flat and sloping obliquely out. Lower surface with prominence in front sloping forward, its crest giving rise to an elongated round dental area sloping slightly down behind, where a crest forms, which gives rise in turn to largest dental area. Latter extends well back and close to inner edge, rounded, and also sloping down concavely behind, while laterally it also extends well towards outer edge. Just external to largest dental area another elongated dental area arising on a slight convexity opposite hind region of anterior dental areas, and extending back opposite deep posterior con-.
