By about 50 mm. in the late metamorphic period, 

 the full complement of caudal rays is present, 8 or 

 9 + 19 + 7 or 8. Table 7 presents data on the num- 

 ber of secondary caudal rays for late metamorphic 

 larvae, juveniles, and adult, and shows that 

 9+19 + 7 was the most frequently occurring 

 complement.

 metamorphio larvae to adults (specimens grouped by 

 size and ratio of rays in ventral and dorsal lobes) 



The minute anterior secondary rays on juveniles 

 and adults are often difficult to discern without 

 dissection. By about 50-60 mm. the anterior- 

 most dorsal and ventral secondary ray is usually 

 completely covered by an elongate, concave, bony
