Specimens 40.0 millimeters long . — The body has become more strongly compressed, 
the back is narrow and high, and the general form approaches that of the adult rather 
closely, the depth now being contained in the length about 2.8 times. The color is 
rather variable. The dark longitudinal bands, described for specimens 25 milli- 
Figure 37 . — Orthopristis chrysopterus. From a fish 38 millimeters long 
meters long, often have disappeared, or the lower one may remain visible anteriorly. 
Occasionally specimens of this size and even larger ones are seen in which the bands 
remain evident. Some specimens, at least, have indications of dark crossbars. In 
life, yellow and green horizontal lines are present on the sides and are most prominent 
on the cheeks and opercles. (Fig. 37.) 
Figure 38 . — Orthopristis chrysopterus. From a fish 70 millimeters long 
Specimens 70.0 millimeters long . — The fish now has acquired essentially the form 
and shape of the adult. The back is prominently elevated, the ventral outline anteri- 
orly is nearly straight, and the snout is pointed. In some specimens the two dark 
horizontal bands described in smaller fish remain faintly visible, dark cross shades 
sometimes are present, and in life greenish and yellowish lines are present on sides. A 
fish of this size is readily identified with the adult. (Fig. 38.)
