PRINCIPAL SIR WM. TURNER ON 



in PI. I. fig. 4. The posterior condyloid fossa was shallow and the foramen was small. 

 A low ridge passed between the front of the occipital condyls. The pharyngeal 

 tubercle was feeble. 



Norma lateralis.— -The lower part of the forehead slightly receded; the glabella 

 and superciliary ridges were distinct, though not very protuberant ; each ridge was 

 separated from the supraorbital border by the supraorbital notch, and a continuous torus 

 supraorbitalis was not produced. The supraorbital trigone was distinct between the 

 superciliary ridges and the temporal curved line, and it sloped outwards to the thick 

 external orbital process. The supraorbital depression was shallow and was not 

 continued across the mid-frontal line. The nasion was distinctly depressed ; the inter- 

 nasal suture was 18 mm. long; the greatest width of a nasal bone was 10 mm. at its 

 free border ; the profile outline of the nose was very concave ; a low keel 3 mm. was 

 present just below the nasion, otherwise the nasal bones were smooth and rounded 

 from side to side. The frontal longitudinal arc was the longest, the occipital was 

 the shortest. The mastoids were relatively feeble, and the skull rested behind on the 

 cerebellar part of the occiput.
