Haddon — Neolithic Cist Burial at Oldhridge, Co. Meath. 573 



protuberant, but the bone is here much corroded ; the superior curved 

 lines are very strong, but there is no external occipital crest. The 

 nuchal region of the occipital is rather flat, but with a pair of lateral 

 -swellings ; the inferior curved lines extend to the base of the mastoids, 

 both of the latter are broken, but, judging from the base of the one 

 on the right side, these were of large size. 



The sutures are very simple ; the sagittal is entirely, and the lamb- 

 <loidal almost totally obliterated. The coronal, which has a complica- 

 tion corresponding to No. 2 of th.e Broca scale, is beginning to be 

 obliterated, especially about the bregma. Both pterions are in H; 

 that on the right side appears to be 14 mm. in width. There are no 

 wormian bones. 



Norma verticalis. — Oval, irregular at occipital protuberance and at 

 glabella, due probably to a slight posthumous distortion, apparently 

 the result of the skull lying on its left side. It belongs to the ovoides 

 group of Sergi,^ but the sides in front of the parietal eminence are 

 straighter than in the typical examples of that group. 



Norma lateralis. — Prominent glabella ; above the ophiyon the low 

 ■even curve of the cranial vault is continued to the lambda ; it is very 

 slightly flattened at the bregma and obelion ; there is a slight occipital 

 protuberance about the lambda ; then the contour is vertical to the 

 inion where it suddenly recedes. On the whole the form is nearest to 

 Sergi's isobathyplatycephalus (or isobathys siculus), and agrees very 

 .closely with the figure he gives of a Neolithic Sicilian skull, although 

 the forehead is not so full and rounded as in the latter. 



Norma occi/pitalis. — A low pentagon with a somewhat rounded 

 roof. 



The following are all the measurements I was able to make : — 

 Olabello-occip. length, 196; glabello-inial length, 188 ; ophryo-occip. 

 length, 191; maximum (parietal) breadth, 144; maximum frontal 

 breadth, 125 ; bi-stephanial breadth, 125 ; maximum frontal breadth, 

 105; basio-bregmatic height, 139; frontal sagittal arc, 140; parietal 

 sagittal arc, 124(?); occipital sagittal arc, 123 (?) ; nasio-opisthial 

 arc, 387; foramen magnum length, 34-5; basio-nasial length, 110; 

 total sagittal circumference, 532; auriculo-nasial radius, 104 (?) ; 

 iiuriculo-bregmatic radius, 125 (?) ; auriculo -parietal radius, 125 (?) 

 horizontal circumference, 540. 



The length-breadth index is 73-5 (the ophryo-occip. index being 

 75'4) ; the length -height index is 70*9, and the breadth-height index,
