but not deep. The minimum breadth of the forehead is 91 mm. The 

 nasal index is 60, which is excessively high even for a Papuan. The 

 forehead rises from the face to a considerable height, and the frontal 

 curve is more gradual than it is among the other female skulls of this 

 group. 



Norma Verticalis. — The frontal eminences are fairly well devel- 

 oped and compensate in a manner those of the parietal, thus giving 

 the skull an elliptical outline. A slight contraction is noticeable at 

 the sides, along the coronal suture. The posterior half of the skull 

 presents a perfectly symmetrical curve. Bizygostephanic index 81. 



Norma Posterior. — Pentagonal, with rather sharp vertex and 

 converging sides; the maximum breadth exceeds the asterionic diameter 

 by 32 mm. The backward position of the parietal eminences is very 

 striking. 



Norma Lateralis. — There is a well marked frontal curve due to 

 the frontal eminences, the curve is then very gradual to obelion, 

 where it rapidly passes downward to inion, when it changes abruptly 

 forward. There is a slight elevation at glabella but no perceptible 

 superciliary ridge. The naso-frontal depression is slight; prognathism 

 is confined to the jaws The curve of the temporo-parietal suture 

 from pterion to the termination of the supra-mastoid crest is exceed- 

 ingly slight. 



Norma Inferior. — Foramen magnum is elliptical in shape and 

 measures 30x25 mm. There is a double interest in the hard palate: 

 first the median portions of the palatine plates have encroached upon 

 the maxillary bones, and, as a consequence, the transverse palatine 

 suture, instead of being straight as is usual, is irregularly oblique on 

 each side; second, there is a broad, well defined torus palatiuus 

 extending from the anterior palatine foramen to the maxillo-palatine 

 suture. Just anterior and internal to each foramen ovale is the 

 anomalous foramen of Vesalius. The jugular processes are more than 

 usually well developed. 



Sutures. — The coronal is exceedingly simple throughout its entire 

 length. The sagittal and lambdoidal are rather complex. Synostosis 

 has taken place in all the sutures in the region of pterion. There are 

 no wormian bones. 



Processes. — Mastoids small; external occipital protuberance very 

 slightly projecting. 



Muscular Impressions. — Faintly marked except the occipital 

 curved lines. The internal pterygoid insertion is rougher than that 

 for the masseter muscle.
