counting from the left margin of this band. Since it is obvious 
that the double scute is the product of what was originally two 
distinct elements, it has been given the value of two inour collected 
data, though we designate it by the number corresponding to its 
first or left-hand element. This point can be made clear by a 
reference to the numbering in figs. 6 to 10. 
The double scutes are generally distributed over the bands as 
can be seen in table 11. There is, however, a tendency for them

Nore, in the left-hand half of the table the numbers in the horizontal rows 
lying opposite the bands designate the first elements upon which the double 
scutes fall. Thus in the first band eight animals had these scutes, falling on ele- 
ments 2, 4, 7, etc., respectively. 
to be localized in the anterior two-thirds of the banded region, or 
in bands one to six. Perhaps of more importance is their lateral 
distribution, which can be shown by dividing each band into 
three equal parts—two of which represent the left and right thirds 
and one the middle third—and determining the number of double 
scutes falling within each of these general divisions. The data 
thus collected is shown in the right half of the table, from which 
it is clear that there is a tendency for these scutes to be localized 
toward the margins of the armor. They fall most frequently
