series from 365 specimens in our collections. 

 Juveniles were identified by the following combi- 

 nation of characters recorded from our juvenile 

 and adult specimens: 



Gill rakers - 



Lateral line pores = 



Pectoral fin rays 



Anal fin soft rays = 



Dorsal fin soft rays -- 



Preocular spine 



Supraocular spine ' 



Interorbital space - 



Black blotch at base of 



spinous dorsal fin ^

Of the 36 Sebastes species off Oregon (Rich- 

 ardson and Laroche 1979), S. flavidus and S. 

 melanops, respectively, have the best fit to the 

 above characters. Sebastes melanops usually has 

 19 rather than 18 pectoral rays and a lower 

 number (<50 rather than >50) of lateral line 

 pores than S. flavidus based on counts made on 

 juveniles and adults collected from Yaquina Bay, 

 Oreg., and the Pacific Ocean nearby (Appendix 

 Table 1). Juvenile specimens were identified by us 

 as S. flavidus and S. melanops using the above 

 characters together with color pattern (intensity 

 of melanistic pigment on caudal fin) and location 

 of capture (S. flavidus from depths >25 m and S. 

 melanops from depths <15 ml. Of 52 S. flavidus
