Palate.- The alveolar margins are absorbed. The post-palatine spine is 

 rounded. The anterior palatine foramen is very prominent. The sutures are 

 regular. 



Temporal fossa. Sutures at right pterion = x : at left pterion = H. 

 The post orbital wall is complete on both sides. 



Base of skull. The glenoid fossae are normally deep. The styloid processes 

 are both intact and measure 20 mm. in length. The basilar suture is closed. 



Dentition. Absorption of the alveolar margin (probably post-mortem) has 

 taken place. 



Mandible. The mandible is absent.

Cranial portion. The transverse curve of the vault is gently rounded and 

 is not keeled. The calvaria has been badly damaged, the extent of the damage 

 being indicated in the tracing of the N. verticalis. The sutures are normal in 

 number and tortuous. The right parieto-frontal (coronal) suture has commenced 

 to close, and is obliterated for about one inch from the bregma. The right 

 parietal foramen is present. 



Facial portion. The supraorbital notches are well marked. The lacrymo 

 ethmoidal suture is present. The infraorbital suture persists on both sides. 

 Nasal aperture is irregularly pyriform. The lower margins are rounded. The 

 nasal spine is small. The nasal bones are regular and fairly large. 



Palate. The general contour is elliptical. The post-palatine spine is 

 rounded. The palatine sutures are regular ; the anterior palatine foramen is 

 deep and prominent. 



Temporal fossa. Sutures at pterion are normal. H. The fossae are deep. 

 Temporal ridge (inferior) well marked. Postorbital wall on right is incomplete. 



Base of skull. The glenoid fossae are deep. The styloid process on right
