Material examined 



A total of 140 specimens, 83.8-340.0 mm, were examined, 

 including the neotype above. See Appendix for catalog 

 numbers and locality data. 



A species of Sebastes with the following combination of 

 character states: body uniformly black to dark blue or 

 gray, particularly at anal-fin base and ventral pectoral-fin 

 rays; peritoneum jet black; symphyseal knob moderate to 

 strong; extrinsic swimbladder muscle with anterior fascia 

 separating sections of striated muscles, otherwise of type I 

 (a-z) of Hallacher ( 1974 1; lateral-line pores 39-50, lateral- 

 line scales 44-60; pectoral-fin (PI) rays 16-19; anal-fin (A) 

 rays 7-9; dorsal-fin (D) rays 13-17; vertebrae 28 (11-12 + 

 16-17).

D XII-XIV. 13-17; A III, 7-9; PI 16-19, 8-11 simple; lat- 

 eral-line pores 39-50(54), scales 44-60; gill rakers 32-37 

 ( 10-11 + 22-27 ); vertebrae 28 (11-12 + 16-17). Meristic fre- 

 quency and statistical data are presented in Tables 2-4. 



Morphometric data and statistics are presented in 

 Tables 1 and 4. Body relatively deep, especially at nape, 

 depth at pelvic-fin base 32.5-42.7% SL; profile of dorsal 

 margin of head steep from snout to nape above anterodor- 

 sal margin of gill slit, flattening to dorsal-fin origin; mouth 

 large, with posterior end of maxilla extending between 

 pupil and posterior rim of orbit, maxilla length 43.6-51.1% 

 HL; symphyseal knob moderate to strong and having blunt 

 tip, lower jaw length 53.4-60.5% HL; mandibular pores of 

 moderate size. Cranial spines weak, in large adults cov- 

 ered by flesh, head smooth. Nasal spine invariably present;
