370 PRINCIPAL SIR W. TURNER ON 



The suprainial part of the occipital squama formed a large rounded protuberance in 

 the female skull (xxx. 3), a character which may perhaps be regarded as sexual rather 

 than racial, and the vertical diameter following the curve from lambda to inion was 

 70 mm. In the male (No. 2) the protuberance was moderate, and its curve was 64 mm. 

 In Nos. 4, 7, and the Jameson skull it was feeble ; the length of the curve in No. 4, owing 

 to the skull-cap being loose, could not be exactly stated, but in No. 7 it was 70 mm. and 

 in the Jameson specimen 52 mm. In the Monro specimen No. 1 and in No. 5 the supra- 

 inial region was almost a plane surface ; in No. 5 the inion practically formed the 

 posterior pole of the cranium ; in No. 1 the lambda-inial diameter was 60 mm. ; in No. 5 

 only 43 mm. The feeble occipital protuberance in three males, and the flattened 

 occipital squama in two others, proved that the occipital lobes of the cerebrum in these 

 skulls could not have projected much beyond the posterior border of the cerebellum. 

 The transverse curve of the occipital bone, immediately above the inion and between the 

 asterionic angles, was 123 mm. in the Monro specimen No. 1 , 126 in 3, 128 in 4, 133 in 

 6, 139 in the Jameson specimen, and 150, 153, and 155 mm. in Nos. 5, 2, and 7 

 respectively. 



Norma lateralis. — The forehead receded somewhat in the male skulls, especially in No. 

 1, but it approached more to the vertical in the female No. 3. The glabella and supraciliary 

 ridges were strong in the males, especially in the Monro specimen ; in No. 6 each ridge 

 was directly continued into the thick upper orbital border as a torus supraorbital, but 

 in the others it was separated from it by the supraorbital notch or foramen. The frontal, 

 between the outer end of the ridge and the temporal curved line, formed a supraorbital 

 trigone and sloped obliquely backwards to the external orbital process. The frontal 

 was not grooved for the passage of the supraorbital vessels or nerve above their foramen 

 of exit. The nasion was deeply depressed. The nasal bones were entire in four skulls, 

 and in them the bridge measured mesially, in a straight line, 13, 15, 17, and 17 mm. re- 

 spectively ; the bones were short and narrow, whilst deeply seated below the prominent 

 glabella the bridge, though concave in profile and continuous with the very depressed 

 nasion, had a shallow keel mesially. In each cranium the occipital longitudinal arc was 

 the shortest, in seven the parietal was the longest, though as between the frontal and 

 parietal the difference in six skulls was only from 1 to 4 mm. The crania rested behind 

 on the mastoids in three specimens, but in the others either on the cerebellar fossae or 

 the occipital condyls. (Plates IT., III. ; figs. 6, 8, 10, 12.) 



Norma facialis. — The floor of the nose was not separated from the incisive region 

 by a sharp ridge, and the nasal floor was often continued smoothly into the incisive area. 

 The maxillo-nasal spine was feeble, and usually continued into the nasal septum. The 

 nasal height in the seven males ranged from 44 to 54 mm. and the mean was only 47*6. 

 The width of the anterior nares in each specimen was more than half the height of the 

 nose, and in some cases much wider. No nasal index was narrow or leptorhine, only one 

 was mesorhine, the rest were platyrhine, and in four the index was above 60, the highest 

 being 65*9 ; the mean of the series was 59'9. In the female skull the lower jaw was
