108 RECORDS OF THK AUSTRAMAV MPSKUM. 



parietals in places arn little if anything less. Tlie thickening is 

 also pronounced in the region of the asterion and the occipital 

 protuberance. The .spongy l)one i.s well marked between the 

 outer and the inner tables. 



In a view from above the cranium in seen to be elongated, and 

 were it not for the fairly well marked paiietal eminences it would 

 be properly termed oi)long-looking. The frontal portion is 

 unusually long, smooth, and rounded. Tt has the frontal 

 eminences distinctly marked. There is no trace of a metopic 

 sutuie. There is a flattened lozensie-shaped area above the 

 glabella. From the upper part of this to the bregma there 

 is a slight ridge. Beliind this the cranium is distinctly 

 scaphocephalic in form, with marked flattening on the left side 

 and still more marked flattening on the right between the bregma 

 and the parietal eminence, and this is associated with an inciease, 

 on the right side, in the distance between the sagittal suture and 

 the parietal eminence (PI. xxKii., fig. 2). The median ridge gives 

 the skull a distinctly pentagonal outline when viewed from behind 

 (PI. xxxii., fig. 3). The temporal ridge of the frontal l)one, about 

 midway in it^ course backwards, divides into an upper and a lower 

 limb. The upper limbs on each side run high up on the vault 

 and at a point about 1cm. liehind the bregma are within 68mm. 

 of each other. Each passes backwards well up on the parietal 

 eminence and strikes the lambdoid suture about midway between 

 the lamda and the asterion. On the parietals these superior lines 

 are markedly double, the distance between the component parts 

 being about 1cm. The superior curved lines of the occipital 

 bone form a large raised crescentic mass. This <!oes not appear 

 to be caused by any diseased conditiori. Unfortunately the lower 

 portion of the occipital, forming the posterior boundary of the 

 foramen magnum, is imperfect. Probably about 14mm. of the 

 arc is wanting. 



The coronal suture is simple from the bregma as far as the 

 stephanion on each side. P>eyond this it is obliterated. The 

 sagittal suture has been dentated in character, but is nearly 

 obliterated except at its posterior portion. The lambdoid suture 

 is well milked and dentated or serrated. There is no appearance 

 of oathological synostosis. 



There is one parietal foramen : it is on the right side. Below 

 the superior curved lines of the occipital there is one foramen in 

 the middle line, and there are two foramina, a right and a left, 

 below this. 



A view from below shows that the sutures on the inner table 

 are all obliterated. The depressions for the blood vessels are 

 fairl)' large and correspond in distribution with those seen in the
