Aug. 1897. Observations on Papuan Crania — Dorsey. 23 



between the mastoids, but projects downwards. There is only 30 

 mm. difference between the maximum diameter and the asterionic 

 diameter. 



Norma Lateralis. — (See PI. VII, Fig. 2.) Forehead prominent 

 and vertex somewhat flattened, as is also the region just above lambda; 

 below lambda the curve passes forward more gradually than usual. 

 The fronto-nasal depression is very slight. Alveolar prognathism 

 very pronounced. Both right and left pterion are formed by a broad 

 frontal process of the temporal bone joining the frontal to the extent 

 of 10 mm. 



Norma Inferior. — Foramen magnum is nearly circular, 34 x30 mm. 

 The condyles are far forward and have a deep backward inclination. 

 The right jugular process extends downwards in a rounded nipple- 

 like projection for about 6 mm. 



Sutures. — Coronal exceedingly simple, sagittal and lambdoidal 

 rather complex. Synostosis has set in about pterion and throughout 

 the sagittal suture. There is a medium size wormian bone to the 

 right of lambda. 



Processes. — Mastoids very small, and very narrow pterygoids. 



Muscular Impressions.— Faint, except the inner and outer borders 

 of the angle of the mandible. Occipital lines scarcely visible. 



Lower Jaw. — Rather small but firmly fashioned. Long coronoid 

 process and broad sigmoid notch. Ramus broad. Mandibular angle 

 115°. 



NO. 40,6 1 I . — Skull of an adult female, of small size but thick and 

 heavy; capacity 1,060 cc. The teeth are all present, in perfect con- 

 dition and but little worn; except the upper incisors and left canine, 

 and the lower left lateral incisor, canine and first premolar which 

 have been lost ; their alveoli are open. In addition to the normal 

 number of teeth, a lower left third premolar has partially erupted 

 between the second premolar and the first premolar. No trace of it 

 can be seen on the labial surface and it is likely that when completely 

 erupted it would have been forced in between the buccal surfaces of the 

 above mentioned teeth. Only the crown of the tooth can be seen; it is 

 of normal size. The ethmoids and vomer have been destroyed. The 

 right zygoma is broken. 



Norma Frontalis. — The orbits are squarish, with nearly perfectly 

 straight axes. The infraorbital space is disproportionately broad. 

 The nasals are large and flattened, nasal openings are rounded and 

 the nasal spine is insignificant. The canine fossae are well marked
