FIGURE 2. — Pelagic larvae (19.4, 25.3 mm) and pelagic juvenile (32.0 mm) of Sebastes entomelas. 



Pectoral fin rays = 17-19, usually 18 



Anal fin soft rays = 7-9, usually 8 



Dorsal fin soft rays = 14-16, usually 15 



Vertebrae = 26 



Preocular spine = present (specimens 

 <343 mm) 



Supraocular spine — present (specimens 

 <343 mm) 



Interorbital space = flat to convex 



Black blotch at base of spinous dorsal fin = pres- 

 ent as fringe along distal margin of fin mem- 

 brane. 



Of the 36 Sebastes species off Oregon 

 (Richardson and Laroche 1979), S. entomelas has 

 the best fit to the above characters. Larvae and 

 juveniles of S. entomelas are similar to those of S. 

 flavidus, S. melanops, andS. mystinus. Large lar- 

 vae and juveniles of S. flavidus and S. melanops 

 lack preocular and usually lack supraocular 

 spines (Laroche and Richardson 1980) which are 

 present in both S. entomelas and S. mystinus. 



Dorsal and anal fin ray counts separate nearly 

 all specimens of S. entomelas and S. mystinus 

 based on count frequency statistics given by
