skulls, and the index was brachyuranic. The teeth were not decayed ; they were not 

 stained, and were partially flattened on the crowns from use. The mean nasio-mental 

 length was 117'7, which is high for that diameter ; the mean complete facial index was 

 92*1, and the mean upper facial index was 55'0 ; both indices were leptoprosopic, and 

 the face was high in relation to the width. In their cubic capacity all three crania were 

 mesocephalic. Each skull had small Wormian bones in the lambdoidal suture. G had 

 a small left epipteric bone, and each orbit showed the rare variety of the superior 

 maxilla, giving rise from its orbital plate to a broad process, which joined the frontal 

 and separated the os planum of the ethmoid from the lachrymal.* The metopic skull 

 had a large epipteric bone on each side and broad ecto-pterygoid plates. 



The Ramree skull and I, both of which came from the South Lushai Hills, were in 

 absolute length much shorter than those above described, and as I was about equal to 

 and the other much exceeded them in breadth, they were distinctly brachycephalic. 

 The outline in the norma verticalis was not elongated, but was broadly ovoid. The 

 vertex sloped downwards to the parietal eminences', which were prominent. The 

 vertical index was less than the cephalic. Both crania were phaenozj^gous. 



The glabella and supra-orbital ridges were scarcely marked ; the forehead was nearly 

 vertical and full ; the nasal bridge was flattened, and the nasal bones in one were short 

 and narrow, in the other longer and broader. The occipito-parietal slope was steep in I, 

 in which this region was not symmetrical and was twisted to the left, probably from 

 artificial pressure in infancy. The occipital arc was the shortest in each skull ; in I 

 the parietal arc, in the other the frontal arc was somewhat the longer. In the male 

 the interzygomatic diameter was 132 mm. 



The upper jaw was moderately projecting, mesognathic in I, but orthognathic 

 in the other ; the nose was platyrhine in I, mesorhine in the other ; the orbital index 

 was high up in the mesoseme group. The face in I was chamseprosopic in both its 

 complete and its maxillary index. In capacity both crania were microcephalic, and the 

 one with the smaller capacity was that of a woman. In I a small Wormian bone was m 

 the lambdoidal and another in the left parieto-mastoid suture, whilst the parieto-sphenoid 

 suture was broad. In the other specimen, both parieto-mastoid sutures contained sutural 

 bones, and the right pterion had an epipteric bone. There were no unusual ossifica- 

 tions at the base of the cranium, and the sutures of the vault were comparatively simple. 



Two skulls of Lushais, obtained during the expedition of 1871-72, have been cata- 

 logued by Dr Barnard Davis in the Siq^plement to his Thesaurus Craniorum. In 

 one the length-breadth index was 73, in the other 76 ; in both the height exceeded 

 the breadth, and the mean interzygomatic diameter was 127 mm. Data are not given 

 for determining the proportions of the height and width of the nose and the degree of 

 projection of the upper jaw. Obviously these skulls had a dolichocephalic character. In 



* Some years ago I described and figured an example of this rare variety in the skull of a Bushman (Challenger 

 Report*, part xxix. p. 12, pi. 1, fig. 4, 1884), and I have recently seen it in the skull of a Papuan from New (■'
