wider in the parietal region, and had a somewhat higher length-breadth index, which 

 placed them in the lower term of the mesaticephalic group. In these three, C, D, and 

 F, the parietal tubera projected, so that the outline of the skull approached the pen- 

 tagonal or coffin shape. There was owly a slight tendency to the formation of a sagittal 

 ridge, and the slope outwards from it to the parietal eminences was not steep. One 

 cranium was phaenozygous ; the rest were cryptozygous. 



Norma Lateralis. — None of the skulls had a very prominent glabella or supra- 

 orbital ridge, though in A they were more distinct than in the other crania ; in A the 

 frontal bone also showed a somewhat shelf-like projection immediately above the external 

 orbital process ; in this skull also the forehead was more receding than in the other speci- 

 mens, in which indeed it approached to the vertical. The vault of the cranium was 

 fairly well arched in the parieto-frontal region, and sloped backwards and. downwards in 

 the parieto-occipital region, somewhat more gently in B than in the other specimens. 

 The occipital squama projected behind the inion ; there was no appearance of parieto- 

 occipital flattening, though D showed a want of symmetry in that region. The skulls 

 rested behind on the cerebellar part of the occiput. The nasal bones had a concave 

 bridge, and projected so slightly that the face was flattened in the nasal region ; the 

 fronto-nasal suture was not depressed. The nasal spine of the superior maxilla; was 

 feeble in some specimens, and in no case strong ; a moderate ridge marked the separation 

 of the incisive part of the upper jaw from the floor of the nose. The incisive and canine 

 fossae were moderate in depth. C and D were more prognathic than the other skulls. As 

 a rule the orbits were high in proportion to their width, but B had a low orbital index. 

 In C, D, and F the nasal index was moderately platyrhine, in A leptorhine, in the rest 

 mesorhine. The teeth had to a large extent been lost, and of those that remained many 

 were worn down and stained. The palate showed no unusual arching. The mastoid 

 processes, temporal and occipital ridges, were moderate. The sutures were not obliterated 

 in any of the crania, though in some, fusion of the bones had begun. Small Wormian 

 "bones were present in the lambdoidal suture in three skulls, and in D the suprainial part 

 of the occipital squama had ossified as a distinct inter-parietal bone. All the skulls, with 

 one exception, had an epipteric bone either on the one or on both sides ; the parieto-sphenoid 

 suture, when present, was usually narrow. The upper part of the coronal suture and the 

 anterior end of the sagittal suture were almost devoid of denticulations. No skull had 

 an exostosis in the auditory meatus, neither was a third condyle or paramastoid process 

 present. No skull was metopic. The skull D showed a hole in the coronal suture 

 25 mm. to the right side of the sagittal suture. The hole measured 6 mm. by 4 mm., 

 and the bone around it had a smooth bevelled margin, whilst the surface of the parietal 

 bone behind it was abraded ; the appearance led one to think that during life the skull 

 had been injured, probably by the cut of a sword. 



The six skulls from the Chin Hills form a homogeneous group, and in their dimen- 

 sions and relative proportions may appropriately be classed together. 



hi the glabello-occipital length the crania ranged from a maximum of 183 mm. to a
