japanese examples the proportion is less than 1 1-5. In those 
from Korea there occurs about an equal number of the narrow 
and broad shapes. These variations in the shape and length 
of the prefrontal and frontal shields are seen in specimens that 
have a decidedly different physiogonomy. 
VARIATION IN POSTOCULARS. 
The only variation these shields offer is where the normal 
number of two is increased to three. This is regularly 
brought about by a division of the upper part of the normal in- 
ferior postocular. Occasionally this shield is merely dented at 
the line where the separation occurs. 
Examples. Normal. ASymmetrical. Increased.

VARIATION IN TEMPORALS. 
The region between the large smooth temporal shields 
and the parietals is covered with a set of small scale-like 
shields that are frequently keeled. These may be referred to 
as supratemporals. The anterior of these lies just behind the 
superior postocular.. It is normally single; the only variation 
is where it is double, the additional shield being formed by an 
horizontal division. 
Examples. Normal. Asymmetrical. Increased.

Occasionally the anterior temporal shield is fragmented, 
the anterior inferior angle being separated by a suture. In 
a few cases the middle temporal shield was horizontally di- 
vided. The posterior temporal is subject to much variation in 
size and shape. 
The middle temporal shield is usually not as deep as the 
anterior, but in many specimens the vertical diameters of the 
two shields are equal. 
Middle Temporal Shield. 
Examples. Lower than Anterior. Equal to Anterior.
