The extreme posterior end of the right maxillary is broken and lacking, and the posterior tip of the supraorbital is broken away. The supraorbital shows only a slight curvature in a vertical direction, with the heaviest portions at the anterior and posterior edges and with the middle part comparatively thin. The optic canal is deep, rounded, and fairly well preserved for a distance of 32 mm. from the base of the supraorbital process. The palatines are lacking, but their shape and size may be judged from the vacuities which remain. The anterior edge of the pala-. Fig. 11.

For explanation of lettering, see Fig. 1. tine vacuities begins almost opposite the maxillary notch as a rounded point and extends in a posterior direction for a distance of 27 mm., where it attains a width of 27 mm., thus being repre- sented in the lateral view as an equilateral, triangular depression. If the palatines were not of a diverging type but followed the suture-like depressions in the maxillaries, they extended a distance of 50 mm. in front of the notches at the anterior edges of the pterygoids. The lacrimal is rounded anteriorly and fits against the maxillary notch and is drawn out and thinned where it attaches to the jugal. The posterior edge is in the shape of a ridge, slightly rounded and higher at its outside edge; and its attachment to the supraorbital process seems to be a straight.
