A fraction of the latter bone is present, defining the lower margin of the orbit, a section of the cheek rim, and a small area of the anteroventral margin of the lateral temporal fenestra. Above this fenestra a stout bar of bone is present, presumably formed anteriorly by the postorbital, posteriorly by the squamosal (the suture between the two is not clear). An incomplete flange of the latter bone extends directly downward as part of the posterior border of the lateral fenestra. The squamosal extended backward beyond t

The antorbital fenestra is a small triangular opening, the apex of the triangle lying anteriorly, at about one-third the distance from orbit to snout tip, the posterior base separated from the orbit by a narrow bony bar. The orbits are large (as, presumably were the eyes) and are subcircular in shape; on the lateral sur- face they occupy nearly the whole height of the skull, leaving but a narrow bar of bone between them and the lower skull margin.
