Dr. G. 8. Brady on the ‘ Oceana’ Ostracoda. 337 
on the top line which stand vertically over the numerals in the body of 
the table. 
An example will make this clear. At a depth of about 220 fathoms, 
in net numbered 66 were captured 16 individuals averaging 7°5 millim. 
in length. The extent of the dark line on either side of the figure 16 
indicates that the 16 individuals varied from 6 to 9 millim. in length, but 
the average length is shown by the position of the figure 16 itself. 
In another case, at a depth of 1500 fathoms, in net 47 were taken 50 
Cheetognatha varying in length from 7°5 to 11 millim., 2 of from 11°5 to 
12°25 millim., and 7 individuals of the lengths indicated, of which the 
longest measured 47 millim. 
The shaded areas serve to indicate the distribution of catches richest in 
individuals of particular lengths at a glance. They are graphic represen- 
tations of the numbers, which have been drawn to an approximate scale.
