INVESTIGATIONS INTO THE HISTORY OF THE YOUNG SQUETEAGUE. 49 
Wareham, taken August 22, averaging 97 nun., the depth averages 26 mm., or 
26.8 per cent. The average width is 13 mm., or 13.41 per cent. 
In 1 specimen, 170 mm. to base of caudal, the depth is 40 mm. 
In 2 adult specimens, 420 (415 and 425) mm. long to the base of the caudal, the 
depth measures 86.5 mm., or 20.59 per cent. The width at the axils averages 67 mm., 
or 15.95 per cent. 
In 2 specimens, 50.6 mm. long to base of caudal, the depth is 113 mm. 
The fish when adult are much more cylindrical than the young, which are com- 
pressed and elevated. In the adult the head is nearly conical, but little deeper than 
Figs. 1 and 2. — The left and right sides respectively of a specimen 120 mm. long taken at Wareham, August 22. Fig. 1 rep- 
resents the general color which is largely due to the color cells in the outer layer of the skin. The streaking which 
is conspicuous in the adult is here still obscured by the general distribution of pigment in the deeper layer shown in 
fig. 2, which represents the coloration of the right side after the removal of the outer skin. 
high; in the young it is much deeper than high. The eye changes its relative propor- 
tions to the size of the head, as in other fishes. This is due to the fact that while the eve 
grows throughout life it does not grow in the same proportion as the rest of the fish.
