60 THE KEILOR FOSSIL SKULL: ANATOMICAL DESCRIPTION 
measurements for skulls of males of a number of racial groups. 
The Keilor skull excels all groups in sixteen of these measure- 
ments; less than half the groups exceed the Keilor skull in twenty- 
one of the remaining measurements. 
The sagittal contour of the Keilor skull closely resembles the 
corresponding contour of South Australian male crania figured 
by Wagner (10, fig. 25, Pl. IIT), and by Fenner (4, fig. 5, p. 258). 
Approximately 50 per cent. of the measurements of the Keilor 
skull exceed those of all groups except three. 
Horizontal Contour (Pl. VIIT) 
The horizontal contour was drawn through the glabella while 
the skull was orientated in the Frankfurt plane. The points 
marked on the drawing are as follows: glabella, F ; occipital point, 
O, as far as possible in the median sagittal plane; and the points 
on each side where the contour cuts the temporal lines, TR and TL. 
Twenty-nine measurements are shown in Table II together with 
the measurements of Wagner’s contours for males of several 
racial groups. In seventeen measurements, those of the Keilor 
skull exceed those of all these racial groups. 
Transverse Contour (Pl. IX) 
The transverse contour was drawn through the poria while the 
skull was orientated at right angles to the Frankfurt plane. The 
points marked on the drawing are as follows: the points at which 
the contour cuts the sharp ridge on the crista zygomatica, ZR and 
ZL; the mid-point, M, of the base line; and the point A, where the 
vertical from M meets the contour. The ends of the contour line 
represent the poria on the skull. 
Twenty-nine measurements of this contour are included in 
Table II together with those of the corresponding contour of racial 
groups. In sixteen measurements the Keilor transverse contour 
exceeds those of the corresponding contours of all the groups. 
Only the Sandwich Island group exceeds the Keilor skull in the 
length of the vertical axis. 
CRANIAL MEASUREMENTS 
(a) Absolute Measurements 
Table I gives measurements of the Keilor skull and mean 
measurements of crania of various Oceanic groups; figures for the 
Oceanic groups are quoted from Wagner (10, Table 23), except 
those for Tasmanians, which are from Wunderly (11) and Morant 
(6). This table shows that the Keilor skull is comparatively large. 
In seventeen of the twenty-eight measurements it exceeds the 
mean measurements of all groups shown in the table. Over 60 per
