mean pairietal spine/HL value. This results from 

 many broken parietal spines on pelagic juveniles 

 as indicated in Tables 4, 5.) 



The five spines of the posterior preopercular 

 series are present on specimens of both species by 

 = 11 or 12 mm. The first spine becomes reduced to 

 a small blunt projection by =70 mm. The third 

 spine is always longest but decreases in length 

 from 20 to 2 or 3% HL during development. The 

 second, third, and fourth posterior preopercular 

 spines and the anterior edge of the first spine of 

 the anterior preopercular series are weakly ser- 

 rated on specimens of S. flavidus <17 mm and S. 



melanops <16 mm. Serrations persist on the 

 third posterior preopercular spine of both species 

 to =32 mm. The second spine of the anterior 

 series is present occasionally (rarely in S. 

 melanops) on one side of the head, particularly on 

 specimens < 13 mm. The first and third anterior 

 preopercular spines are visible on specimens <27 

 and 25 mm (S. flavidus and S. melanops , respec- 

 tively), become reduced to small bumps, and are 

 no longer visible on specimens >31 and 29 mm. 



The inferior opercular spine forms by =11 or 12 

 mm and is sharp tipped by =15 or 16 mm. (Two 

 inferior opercular spines were observed on one
