greatest depth of the body is contained from 8: to 6: times in the 
total length in young fish less than 124 mm. long, while in adults 
it is contained only from 45 to 5: times. In the proportions of 
the total length without the caudal to the greatest depth the 
differences are smaller, the figures 6 to 61 for fish under 67 mm. 
long, 5 for individuals between 90 and 123 mm. long and from 
4 to 48 in the adult. The proportion between total length and 
length of head is less different at different ages, and that between 
head and body (without the caudal) and head is still more uniform, 
practically no difference existing between young and adult. In 
length of eye in that of head there is a great difference. In speci- 
mens between 56 and 92 mm. long it is roughly from 2s to 3s 
times, in one 123 mm. long 4s times, in the adult 71 to 8 times. 
In the young the spiny dorsal ray is also proportionately more 
slender and bears relatively much longer denticulations than in 
the adult. In the young these denticulations have a spiny char- 
acter.
