 Palatomaxillarv suturt 



.Xntrridiiw the .superciliary ridges and the glabella 

 are prdimunced ; there is no evidence of a metopic 

 .suture. A supraorbital foramen is present on either 

 side. 



The orbits are equal, their ratios being 4 '2 \V, 

 1, -3 II. There are traces of both infraorbital sutures, 

 especialh' of the left one, and the malar bones are 

 excluded from the inferior orbital fissure both on 

 the right and the left sides. The infraorbital fora- 

 mina are duplicated on each side. 



The basal aspect presents little of interest. The 

 palate is normal, all the teeth are missing — some 

 ante-, some post-mortem. The palatine suture is irregularly cruciform ( I'ig. 'h ), 

 tile left palate bone being somewhat the wider. (Jn the right side of the almost 

 circular foramen magnum is a posterior condylaid canal. 



There is partial synostosis of the sagittal, coronal, and laml>tl()id sutures. 



SPECIMEN 5. 

 Plate xl, and Fig. 62. 



Skull. Adult, aet. c. 25-35. 



Dolichocephalic, Prognathous ; Mesosenie ; I.eptorrhine ; Dolichuranic. 



Capacity — 1345 cc. 



Tapuo-melanesian : New Britain. Reg. A. 1 142S. (Prcs.. Mrs.. A. C. Magarey.) 



In norma verticalis this skull is long and oval, and laterally resembles the 

 skulls previously described. The more anterior of the two grooves of compres- 

 sion is slight and hardly visible; the other is cjuite definite, and the bregmatic 

 swelling included between the two is in consecjuence somewhat ill-defined. 



The coronal suture is marked at the pars coiii- 

 plicata by several small Wormian bones, and at the 

 pterionic angle on each side is an epipteric bone — 

 that on tlie right being practically fused, and so 

 [jroducing a frontosquamous articulation. The 

 parietal eminences are slightly marked. 



In the lambdoid suture are several Wormian 

 Ijones (partially obliterated), more or less symmetri- 

 callv disposed. The occipital bone is almost flat, 

 from lambda to opisthion. 



In iioniia frontalis the glabella and superciliary 

 ridges stand out very prominentl)- — more so than
