1964, 1966). Originally it was known as "Pithecanthropus V," and as such 

 it was listed by me (Tobias 1967a, p. 94). As explained by von Koenigs- 

 wald (1968) in an appendix to the recent paper by Sartono (1968). Teuku 

 Jacob decided subsequently to add the Modjokerto child cranium to the 

 numbered series, and it became "Pithecanthropus V." This made the 1963 

 cranium "Pithecanthropus VI," or, as listed here, H. erectus VI. According 

 to a letter I received from Professor von Koenigswald in 1966, the ca- 

 pacity is about 975 c.c. This figure was cited by Jacob (1966), while von 

 Koenigswald (1967, p. 650) said it had a capacity of "etwa 975 cm. 3 " It 

 should be reiterated that this value, entered in my list here as the capacity 

 of H. erectus VI, refers to the same item as the 975 c.c. entered in my 

 (1967a) list as that of H. erectus V. 



Homo erectus VII of Indonesia. This cranium was found in January 

 1965 in the Sangiran area, though outside the actual Sangiran dome (Suradi 

 1965; Sartono 1967. 1968). In his 1968 paper, Sartono lists the cranial 

 capacity as ca. 900 c.c, while in a letter to me dated 29 April 1969 Pro- 

 fessor von Koenigswald indicated that a new reconstruction of the "Pithecan- 

 thropus VI I" cranium had yielded a slightly higher capacity, namely 

 about 930 c.c. The capacity of this cranium was not included in the 

 up-to-date list published in the appendix to Chapter YIII of Tobias 

 1967a. In the present list, both values are indicated, but for purposes of 

 calculation an intermediate value of 915 c.c. has been employed (Fig- 

 ure 28). 



Summary on Indonesian Homo erectus 



The capacities of 6 Javanese crania. 1 from Trinil and 5 from 

 Sangiran. thus range from 750 c.c. to 975 c.c. (Table 13). Von Koenigs- 

 wald's new value of 750 c.c. for H. erectus IV is the smallest value so 

 far obtained for a cranium that conforms to the anatomical hallmarks 

 of H. erectus. It is interesting to note that this value is just exceeded by 

 the capacity of a single gorilla (752 c.c— Schultz 1962). 



The mean for the 6 cranial capacities is 859 c.c. The standard 

 deviation may be computed from the size of the extreme range, with the 

 aid of Table 6 of Lindley and Miller (1953. p. 7) and of Table 1A of Simp- 

 son, Roe, and Lewontin (i960, p. 141 >: it is 89 c.c. If the 6 available crania 

 from Indonesia represent the middle reaches of the distribution for the Java-
