THE KEILOR FOSSIL SKULL: ANATOMICAL DESCRIPTION 61 
cent. of the measurements of the Keilor skull are greater than the 
mean measurements of all the racial groups recorded in Table I. 
Hrdlitka (5) measured nearly 1,000 Australian skulls. The 
following table shows that three of the more important measure- 
ments of the Keilor skull are comparable with the maxima 
recorded by Hrdlitka, for the corresponding measurements of 
skulls of males of six Australian regional groups:

(b) Cranial Indices. 
Six indices have been recorded for the Keilor skull. 
The following table compares these indices with corresponding 
indices for eight racial groups, data for which are quoted from 
Wagner (10), Wunderly (11), and Morant (6):

*A from Wunderly (11) and B from Morant (6). 
In respect of four of the six indices, the values for the Keilor 
skull occupy the middle third of the total range of nine racial 
values, while, in the remaining two indices, they lie in the lowest 
third. 
SUMMARY AND CONCLUSIONS 
The foregoing notes reveal the following particulars about the 
Keilor skull: 
1. It combines Australoid and Tasmanoid characteristics in 
about equal proportions.
