A. Eggs. 



1. The floating spawn. (Fig. 1) . 



2. Isolated eggs. (Fig. 2) ...... 



B. Larval Forms. 



1. Nevvdy-hatched larva. (Fig. 3) ..... 



2. Larva seven to eight days old. (Fig. 4) . . . . 



3. Larva at the completion of the absorption of the yolk. (Fig. 5) 



C. Post-larval Forms. 



1. With three well developed first dorsal rays, and beginning of second 



dorsal and anal fins. (Fig. 6) .... . 



2. With five distinct rays in first dorsal fin, the elements of the second 



dorsal and anal fins complete. (Fig. 7) . 



3. With six rays in the first dorsal fin, the first ray still small, but 



appearing above the contour of the head, second dorsal and anal 

 fins complete. (Fig. 8) ..... .
