The articular of the lower jaw is closely applied to it. The occipital plate is weathered and broken. There is a large foramen magnum placed high up. The squamosal only forms the edge of the plate and the outer boundary of the lateral post-temporal fossa. Most of the side of the occipital plate seems to be formed by the tabulare. Below the basioccipital condyle there is a vertical mass of bone as in the other Dinocephalians. The lower jaw is deep and displayed only in outer view. Its total length is about 215 mm. The dentary covers almost the whole of the anterior half of the jaw, the lower border being formed by the. FIG. 8.—Anterior view of vertebra of Hoschosaurus longiceps. x splenial; and the dentary extends backwards along the upper border of the jaw for about four-fifths of its length. This posterior process is much more slender than that seen in Dimetrodon. The dentary carries 5 or 6 teeth, forwardly directed and presumably diminishing in size posteriorly. The splenial forms a small portion of the symphysis and is only visible along the lower border of the anterior half of the jaw. The back of the angular is missing; but the notch in its lower border must have been a small one. The bone overlaps the articular which, from below, is seen to be swollen vertically and to pass forwards and upwards. Six consecutive vertebrae are preserved, without doubt anterior dorsals. The centra are short with circular biconcave ends. The lower border is concave with a slight median ridge. The sides are.
