64 THE KEILOR FOSSIL SKULL: ANATOMICAL DESCRIPTION 
Contour Drawings 
The cranial contour drawings shown in Pls. VII, VIII and IX 
are made in accordance with directions given by Bennington (1) 
and Wagner (10). The modified kubus enables the sagittal and 
the transverse contours to be drawn at right angles to the Frank- 
furt plane, and not with the orientation used by Wagner and 
others. A skull may be supported face downwards while the trans- 
verse vertical drawing is made, and thus both right and left sides 
are directly represented in the drawing. 
Craniometric Measurements 
The anatomical points, between which measurements were made, 
are those defined by Buxton and Morant (3), with certain reser- 
vations suggested by Wagner (10). Points not anatomically 
obvious have been treated as closely as possible in accordance with 
the directions given by these writers,
