Aug. 1897. Observations on Papuan Crania — Dorsey. 25 



Lower Jaw.— Weakly developed. Body narrow and thin; mandib- 

 ular angle open: mental projection slight; height of symphysis 

 25 mm. 



NO. 40,616. — Skull of adult female. The cranium is large and 

 well formed; capacity 1,345 cc - The lachrymals, ethmoids and 

 vomer have been destroyed. The left upper third molar has never 

 erupted. Of the lower jaw the left, second and third and the right 

 third molars have disappeared, and the alveoli are entirely absorbed. 

 The alveolus of the right upper third molar shows that tooth to have 

 been in an atrophied condition. The upper right second molar and 

 first premolar and the left second molar, together with the lower right 

 first molar and left second and third molars are in situ. None of the 

 alveoli are absorbed. The teeth present are somewhat worn, especi- 

 ally the lower right molar, which has been ground down from before 

 backwards. 



Norma Frontalis. — Forehead retreats from the face; very slight 

 glabella. The orbits are squarish with a noticeable droop to the 

 axes. The infraorbital region is broad. The nasals are broad and the 

 inter- nasal and naso-frontal ancJija^QHitiaxillary sutures are synostosed. 

 The nasal openings are rounded, s^jthrMery weak nasal spine. Canine 

 foss;e fairly deep. The form of tl^fa^efisiftejarly square. 



Norma Verticalis. — Parietal eminence prominent. Phaenozygous. 



Norma Posterior. — Pentagonal in form, but nearly as broad as 

 high. Superior angle very open. 



Norma Lateralis. — Both right and left pterion are formed by a 

 broad frontal process of the temporal bone. The curve of the temporo- 

 parietal suture is very slight and quite the opposite from the European 

 type. Forehead is low but curves backwards gradually, flattened 

 over vertex, with strong occipital development between lambda and 

 external occipital protuberance, which shows strongly in profile. 

 The superciliary ridges are slight, with scarcely any naso-frontal 

 depression. Marked alveolar prognathism. 



Norma Inferior. — Foramen magnum of oval form, with the con- 

 dyles far forward; measures 39 x 33 mm. Its plane has a slight back- 

 ward inclination. The foramen ovale is of exceptional size, that of 

 the left side measuring 9x5 mm. External pterygoid plates broad, 

 inner correspondingly narrow. Palate shallow. 



Sutures. — Very simple (No. 2 of Broca's scale). The coronal 

 suture below stephanion is completely effaced. This is almost the 

 condition of the posterior four-fifths of the sagittal and nearly all of 

 the lambdoidal. There are three large wormian bones at lambda;
