X Lettering as in Fig. i. layer. In (f there is posterior to supraorbital i a small, rounded supraorbital 2; it seems not to be broken off posteriorly ; some bone fragments posterior to it may be other parts of the same bone, perhaps fragmented during an early stage in the ontogenetic development {So, PL 2, fig. 2). The dermosphenotic [Dsph, PI. i ; PL 2, fig. 2 ; Text-figs, i, 2) is missing in most specimens, and in ^2d only fragments of it are visible. In 38107, however, a rather well-preserved, roughly triangular dermosphenotic is present with its dorso- posterior margin convex and with its slightly concave and thickened anterior margin constituting the postero-dorsal border of the orbit. The shape of the exposed surface of the parietal (Pa, Text-figs, i, 2) is difficult to determine because of the poor preservation of this part of the skull roof, but it seems to be roughly square. The dermopterotic (Dpt, PL 2, figs. 1-3 ; Text-figs, i, 2) is comparatively narrow in its anterior part lateral to the posterior part of the frontal, but it broadens posterior to that bone on the dorsal surface of the skull, where it meets the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Museum (Natural History).
