Behind these again the upper border spreads out laterally and is deeply concave, the concavity being marked oif posteriorly by a prominent tubercle (t), behind which is the thin upper edge of the expanded portion which, as above described, bears the articular on its inner face. Ventrally the sur- angular receives the upper border of the angular in front, while behind its outer face is extensively overlapped by that bone. The angular {ang.) forms the lower border of the posterior part of the mandibular ramus ; it consists of an elongated ventral portion, the upper edge of which, as just mentioned, interlocks with the ventral border of the surangular; below and internally it is closely united with the splenial. Posteriorly it widens out and forms the postero- inferior angle of the jaw; in this region it extensively overlaps the surangular Text-fig. !
