The transverse curve of the calvaria is slightly scaphoid. The sutures 

 are normal and generally open. About an inch on each side of lambda are 

 two small bones between the sutures, which, from their position, are probably 

 true interparietal bones. 



The lachrymal fossae arc large. The nasal bones are regular in shape. 

 The nasal spine is prominent. 



The arrangement of the bones and the sutures at pterion is normal. 



On the base of the skull all prominences are well marked, the surface in 

 general being rough. The hard palate is deep behind, but slopes rapidly 

 downwards interiorly. The surface is rough and pitted. A spicule of bone 

 forms a foramen for the palatine vessels in front of the normal post, palatine 

 foramen. 



The external pterygoid processes are broad and distinctly wing-like in 

 shape. The spines of, the sphenoid are prominent. The spinous processes are 

 long, thin, and tapering. The basilar suture is closed. The mastoid processes 

 are prominent and the grooves deeply marked. The superior and inferior 

 curved lines of the occipital are well marked. 



Dentition. On both sides the two post, molars are lost and their alveoli 

 apparently absorbed. The eruption of the teeth was apparently somewhat 

 irregular. The remaining teeth are sound. 



The mandible is absent
