Pelagic young of Sebastes iSebastomus) heliomaculatus: (A) transforming larva, 13.4 mm SL; (B) 

 transforming larva, 18.4 mm SL; (C) pelagic juvenile, 22.4 mm SL; (D) pelagic juvenile, 41.6 mm 

 SL. From Richardson and Laroche (1979). 



ontogenetic changes in head spines (e.g. loss of infra- 

 orbitals and anterior preoperculars; decrease in the 

 relative size of the parietalsl occur in S. helvomacu- 

 latus larger than S. ensifer (Figs. 2 and 3). 



Pelagic juveniles of other Sebastomus species A field- 

 caught 21.0-mm pelagic juvenile of S. chlorostictus 

 illustrated in Matarese et al. (1989) and Kendall 

 (1991) is generally similar to specimens of S. constel- 

 latus and S. ensifer described in this study. In con- 

 trast to these species, the nape area in S. chlorostictus 



appears to lack pigment. In S. chlorostictus the dark 

 pigment saddle extends from the first to sixth dorsal- 

 fin spines, becomes wider mid-laterally on the tmnk 

 and appears to extend to the abdominal region. The 

 caudal peduncle pigment is equally heavy and forms 

 a complete band around the peduncle in the 21.0-mm 

 specimen. Also, the dorsal and anal fin rays appear to 

 be shorter than those in S. ensifer.
