shows how nearly equal they were in their mean relative proportions, so that they fall 

 into the mesognathic group. It was exceptional to see a marked degree of alveolar 

 prognathism. 



The mean nasal index was 48*6, thus on the average the nasal height was some- 

 thing more than twice the width ; though in the individual specimens the index ranged 

 from 40 "0 to 591. They came collectively just within the mesorhine group, but five 

 specimens had the index above 53, i.e., were platyrhine, and fourteen were leptorhine. 

 The mean orbital index was 85*0, though in individual orbits it ranged from 73*2 to 97"3 ; 

 the skulls collectively came within the mesoseme group, though ten were megaseme and 

 fourteen were microseme. The mean palato-maxillary index was 119*7, and the range 

 was from 106*8 to 136'0. In twenty-four specimens the index was 115 and upwards ; they 

 were brachyuranic, and showed a wide palato-alveolar diameter in relation to the length. 



As regards the cubic capacity it must be remembered that all the skulls were males. 

 The mean of twenty-eight specimens capable of being measured was 1388 c.c, which 

 places them in the mesocephalic group. One skull had a capacity of only 1160 c.c. ; 

 two were 1600 and 1670 c.c. respectively, and one had the remarkably high capacity 

 1820 c.c. ; but these were exceptional, and the usual capacity ranged from 1240 to 

 1450 c.c. 



To sum up, the Burmese proper are brachycephalic ; as a rule the cranial breadth is 

 greater than the height ; the face is low, chamseprosopic ; the upper jaw is moderately 

 projecting, mesognathic ; the nasal width is moderate in relation to the height ; the 

 orbits vary in their dimensions, but the mean is mesoseme ; the palato-alveolar arch 

 is wide in relation to the length ; the cranial capacity is moderate. 



Part II. Table VI. 



In this part are included the description of some skulls from Burma, which appa- 

 rently belonged to tribes that form distinct elements in the population, and which may 

 very properly be considered apart from those which belonged to the customary type of 

 the people. With one exception, they were all apparently men. 



H. T., No. 159 (Table VI.), referred to on page 728, though catalogued by the 

 Henderson Trust as a Burmese skull, is not associated with any definite locality, and 

 on this account and from its special character it has not been included in the preceding 

 description. In the proportion of length and breadth it was distinctly dolichocephalic 

 (72*2), and its outline in the norma verticalis was so elongated that it presented a 

 striking contrast to the usual brachycephalic Burmese cranium. It was keeled in the 

 anterior half of the sagittal region, from which the parietals sloped downwards to their 

 eminences, below which the side walls of the skull were almost vertical. It 

 differed also from the customary type of the Burmese skulls in having its basi- 

 bregmatic height and vertical index considerably higher than its greatest breadth 

 and cephalic index. The skull was phsenozygous. The forehead wa3 narrow, but was
