On each parietal bone, beginning about half way down the sagittal 

 suture, begins a broad groove which extends downwards and ends in 

 the lambdoidal suture just 'below lambda. Seen in profile the two 

 grooves are very plain, with the sagittal suture at a median elevation 

 between them. 



Norma Lateralis. — (See PI. II, Fig. 2.) The curve of the vault 

 of the cranium may be divided into five regions: from ophryon to 

 metopion, from metopion to obelion with a very slight depression 

 just posterior to bregma, from obelion to lambda, from lambda to inion, 

 and from inion to opisthion. The frontal development is fairly good; 

 the vertex is somewhat horizontal ; there is a sharp break in the 

 curve at obelion and the occipital point is half way between lambda 

 and inion. There is a large amount of alveolar prognathism, the 

 teeth also have a strong forward projection. The malar bone is 

 excluded from the spheno-maxillary fissure by the articulation of the 

 sphenoid with the inferior maxillary bone. The temporal border of 

 the malar bone is prominently marked. 



Norma Basalis. — (See PI. Ill, Fig. 1.) The foramen magnum 

 is long and narrow, measures 36 x 25 mm. ; its plane is directed back- 

 wards. The condyles are far forward, slightly oblique, and encroach 

 somewhat on the anterior border of the foramen magnum. The 

 basilar process is long and narrow, with deep, well-defined pharingeal 

 and navicular fossae. The right foramen spinosum has its posterior 

 border open into the spheno-petrossal fissure, while the foramen 

 ovale is a mere slit-like opening. The posterior condylar foramina 

 are absent. There are two right and one left mastoid foramina. 

 Palate is long and narrow, U-shaped, and is 18 mm. deep in parts; 

 there is a gradual slope to the incisor alveoli. The roof of the palate 

 is rough and thrown into irregular folds. The postglenoid processes 

 are heavily developed. 



Sutures. — The coronal is exceedingly simple, the lambdoidal is 

 slightly complex, and the sagittal is very deeply but coarsely serrated. 

 The coronal suture in places has begun to synostose. There is an 

 epipteric bone at right pterion, and it is difficult to determine if it 

 corresponds to the upper angle of the alisphenoid or is an extra bone ; 

 it cannot belong to the temporal or parietal. On the left side the 

 temporal is 10 mm. from the frontal bone. The malo-maxillary 

 suture is synostosed and almost obliterated. 



Processes. — The mastoids are short, thick and massive. Sty- 

 loid processes small. The sphenoidal spines are long and unusually 

 thick. The external pterygoid plates are both broken ; the internal
