Posteriorly the pterygoid unites with the quadrate and squamosal. The articulation with the quadrate has been adequately described under that bone. The pterygoid unites with the squamosal above the quadrate, and curves with it around the anterior end of the otic. ChDP6 Fig. 8. Medial view of posterior portion of the right half of skull with the braincase removed, x 1. notch. The quadrate ramus and ascending process of the pterygoid are continuous. The latter arises just behind the basipterygoid articu- lation to meet the descending process of the squamosal. The articulation for the basipterygoid process of the basisphenoid is shown in its entirety in two fragments which bear the number 1090. It lies opposite the point where the quadrate ramus of the pterygoid joins the main body of the bone. The basipterygoid process fits into a fossa on the ventral side of the pterygoid. This fossa is crescentic in outline with rather high walls which project about 3 mm. below the ventral surface of the bone. The fossa is only about half closed over from its posterior edge. The pterygoid with the exception of the quadrate ramus is com- pletely covered on the palatal surface by shagreen teeth. Epipterygoid. The epipterygoid was either absent or very small and lost, or may have been entirely cartilaginous. Nothing was found in any of the specimens which could be identified as this bone. This is.
