include the form in his genus Diictodon, characterised by the enclosure 

 of the pineal foramen by the preparietal. It is clear, however, that the 

 preparietal forms only a portion of the border of the foramen, the 

 larger part of the opening being enclosed by the parietals, which are 

 fused together in their anterior half. 



The figure shows the preparietal to be remarkably short and broad, 

 of irregular shape and with convoluted borders. Moreover, there does 

 not appear to be a distinct postf rental. A possible frontal-postfrontal 

 suture on the right-hand side of the skull is not paralleled on the other 

 side, and it is thus probably a crack. 



The parietal bar has a deep median groove behind the pineal 

 foramen, flanked by the crests formed partly of parietal and partly of 

 postorbital.

 Ixiii, fig. 10. 



Founded on a somewhat crushed and weathered preorbital portion 

 of a skull. Snout extremely short, bringing the front of the palate 

 almost under the orbit. Nasals thickened to form a rounded boss 

 overhanging the nostril. Orbit large. Frontals short and com- 

 paratively narrow. 



The form, according to Dr. Broom, is comparable with D. strigiceps ; 

 but the latter has a much larger nostril and has the caniniform process 

 much farther back.

The type and only known specimen is in an incomplete and crushed 

 condition, but its features are sufficiently well displayed to differentiate 

 it from other species. The skull is remarkable in being as broad as it
