Description of Individual Crania : — 



(1). Calvarium of an adult male ; very much weatliered ; of fair 

 size. Glabella small, but frontal sinuses fairly large. Forehead high 

 and perpendicular. Inion and superior curved line very lightly 

 marked, but mastoid processes very large, and bulged outwards ; 

 digastric grooves deep. Sutures complex and much obliterated. 



(2). Female (?), much broken and weathered. Sutures very 

 complex, and obliteration advanced. Markings slight. Forehead 

 perpendicular, and frontal sinuses small. 



(3). Probably male, small and very much broken. Markings slight. 



(4). Male, extensively mutilated, the whole cranial base being 

 broken away. Forehead high and straight. Markings very strong, 

 the inion being immense. Viewed in norma verticalis the outline is 

 almost quadrangular. 



(5). Calvarium undoubtedly female, with very slight markings. 

 Straight forehead, and complex much obliterated sutures. Norma 

 verticalis oval, with broadest part anterior. 



(6). Male, with strong markings, mastoids being very large, and 

 projecting laterally. Perpendicular but low forehead. Small frontal 

 sinuses and projecting occiput. Norma verticalis almost quadrate. 

 The meningeal vessels have grooved the bone very deeply. 



(7). Probably female, small, with a regular oval outline. Glabella 

 very small, and other markings slight, with the exception of the 

 mastoid processes and frontal sinuses, which are rather large. 



(8). Probably male. Shape, when viewed in norma verticalis, a 

 blunt oval, approaching the quadrate. Markings slight, and frontal 

 sinuses small. Occiput projects above, but is flattened oif below the 

 superior curved line. Sutures simple and unobliterated. Metopic 

 suture persistent. Condition, very much broken. 



(9). Female calvarium, very much shattered, the whole base being 

 broken away. Shape, nearly quadrate. Forehead perpendicular, and 

 glabella of medium size. 



(10), Probably female. Specimen is very much weathered, and so 

 shattered that two measurements only can be taken. There is a very 

 peculiar pit, about the size of half a walnut, occupying the spot on 

 which the inion ought to be situated. It is probably due to the 

 pressure of a wen or tumour, 



(11). Male (?) calvarium of regular oval form, with perpendicular 

 forehead, and large glabella and superciliary ridges. Condition : this 

 specimen consists only of a much weathered and broken cranial vault.
