A scale lateral reconstruction of the appearance of the closed jaws was produced by reference to the right jaws of and the toothless jaw of , as above. This was then reversed (so as to appear to face to the left) and reduced slightly until it fitted the toothless restoration of In this way the composite lateral reconstruction (Fig. I) was derived. Skull of The skull of this 'juvenile' individual is very fragmentary, and has been mounted on thin steel bars to which the fragments have been glued. It is less complete than that of , and adds little to the description. Three teeth, preserved in situ on the premaxillae, show the diagnostic ornamentation. Fragments of the frontals and parietals are preserved, and the supraoccipital, exoccipital- opisthotics, basioccipital and basisphenoid were figured by Andrews (1910 : pi. 9, figs 4, 4a, 5; the 'median foramen' in the basisphenoid, figured and labelled/or., is actually a hole that has been drilled to facilitate mounting on a steel peg). The form of the occipital condyle, in which the exoccipitals are involved, is exactly as in Parts of the right squamosal and both quadrates are also preserved. The right ramus of the lower jaw (Andrews 1910 : pi. 9 fig. 6) contains 24 tooth sockets with posteriorly a small depression suggestive of a 25th socket developing. The left ramus is heavily eroded. In this 'juvenile' specimen the angular extends slightly posterior to the ossified part of the articular, which was completed posteriorly in cartilage. The postcranial skeleton.
