Haddon — Neolithic Cist Burial at Olclbridge, Co. Meath. 575 



very slight anterior sagittal keel, but between tbe prominent 

 parietal eminences there is a sagittal groove ; the cranial walls 

 are flat. There is a slight bulging of the occipital squame ; the 

 occipital muscular impressions are strong. The mastoids are large. 

 The coronal and sagittal sutures are nearly obliterated ; the lamb- 

 doid is complex. There are no wormian bones. The pterion is in 

 H (right, 16-5 mm. ; left, 16 mm.). 



The cheek-bones are not specially prominent ; the nose is prominent, 

 and the nasal bones are well formed and not constricted ; the apertura 

 pyriformis has slight pre-nasal fossae ; the palate is large and broad. 



Norma verticalis, — The cranium may be placed in the sphenoides 

 stenometropus group of Sergi ; that is, the biparietal enlargement is 

 far back, and there is a gradual and sensible reduction in width 

 anteriorly ; the sides of the cranium are flattened ; the occipital is 

 rounded ; the skull is slightly phsenozygous. Norma lateralis. — In a 

 side view, the cranium appears long and depressed, with a slight 

 occipital bulging; it appears to me to be intermediate between Sergi's 

 platycephalus and ellipsoides depressus. Norma occipitalis. — The 

 sides and base are flat, and together form a transversely- elongated 

 oblong with a fairly well-rounded top. 



The cranium is dolichocephalic, tapeinocepbalic, very orthognathic, 

 very leptoprosopic, very leptorhine, very microseme, especially in the 

 right orbit ; the naso-malar index is prosopic ; and the palate is 

 brachyuranic, 



No. 2. — Cranium of an adult male. — The glabella and supra-ciliary 

 ridges are more prominent than in the preceding skull ; there is a 

 sagittal keel which extends from the glabella to the anterior third of 

 the parietals ; the frontal eminences are moderately prominent ; there 

 is a slight depression at the obelion between the prominent parietal 

 eminences ; the sides of the skull are ill-filled. The cranium is flattened 

 posteriorly about the lambda, but there is a slight occipital bulging ; 

 the inion and the muscular impressions are prominent. The mastoids 

 are large ; the sagittal suture is largely obliterated, the sutures are 

 complex. Pterion in H (right, 13 mm., left, 14 mm.); no wormian 

 bones. 



The face is fairly broad, with wide and fairly prominent cheek 

 bones, and a strong concave nose, the nasal bones are not pinched, the 

 apertura pyriformis has slight prenasal fossae, the palate is horse- 

 shoe shaped. 



Norma verticalis. — This is an elongated, somewhat oval cranium, 

 but enlarged in the region of the parietal eminences, and may be
