Figure 28: Side view of calvaria of Homo erectus VII from Sangiran, Indo- 

 nesia. This is one of the most recently discovered Homo erectus crania 

 from Indonesia and has an estimated total cranial capacity of about 

 915 c.c. 



nese H. erectus, the population limits would thus be set at 592 to 1126 c.c, 

 on the basis of 3 S.D.s above and below the sample mean.* 



My Indonesian H. erectus series differs from that compiled by Ashton 

 (1950). He included the 6 Ngandong crania under "Pithecantliropus pe- 

 kinensis" of which he states that Weidenreich (1943) gave the capacities of 

 1 1 specimens. In fact, Weidenreich gave the capacities of only 5 specimens 

 of P. pekinensis (i.e., H. erectus pekinensis), although he mentioned an- 

 other 2 estimates, 850 and 1300 c.c, in the text. When to these 5 Pekin 

 cranial capacities are added Weidenreich's figures for the 6 Ngandong crania 



* Since this passage was written, yet another cranium has come to light in the Sangiran area, 

 namely that of H. erectus VIII; it was discovered on 13 September 1969 (Suradi 1969, Sartono 

 1970, 1971). Professor S. Sartono has very kindly permitted me to quote his unpublished esti- 

 mate of the cranial capacity: it is ca. 1029 c.c. (letter from Sartono dated 30 March 1971). This 

 is the largest capacity yet found among the 7 Indonesian crania of H. erectus. The range of 

 capacities thus becomes 750 c.c. to 1029 c.c. and the new mean 8S3 c.c. (in place of 859 c.c). The 

 amended standard deviation is now estimated to be 103 c.c. instead of 89 c.c. On this basis, the 

 population limits are widened somewhat, being set at 574 to 1192 c.c. in place of 592 to 1126 c.c.
