The skull has lost the occipital and parietal regions, but the missing part is inferredto have been short from the circumstance that the squamosal bone descends to formthe articulation for the lower jaw, in a way which may be compared with that shown ^ Oynodont molar teeth are drawn in Plate 88, fig. 6. t Oat.
