24b. Coronal spines none ; ridges with entire edges. 



25a. Gill rakers much higher than wide; dorsal 

 spines high over y 3 of length of head; inter- 

 orbital somewhat convex posteriorly, so that 

 the postocular spines do not enter the profile; 

 profile but slightly indented behind nasal 

 spines; mouth small, upper jaw usually not 

 extending beyond vertical from hind border of 

 orbit, and contained 5.3 to 5.7 times in stand- 

 ard length; ridges of head narrower; dorsal 

 spines scarcely excised posteriorly; a pale 

 area along posterior f$ of lateral line more or 

 less distinctly evident. Range: Sitka, Alaska, 

 to Yaquina Bay, Oregon. Marine. Common. 



Yellow-backed Rockfish 



203. Sebastodes canrinus (Richardson) 



25b. Gill rakers and dorsal spines the same as in 

 25a; interorbital more or less concave, so that 

 the postorbital spines may enter the profile 

 (tips of spines sometimes not entering profile 

 in maliger) ; profile deeply and widely indent- 

 ed behind nasal spines. 



26a. Interorbital only moderately concave; the 

 orbital rims not greatly thickened and ele- 

 vated, not abruptly entering the profile; 4 

 posterior interspinal membranes of dorsal 

 rather deeply incised to about l /z or J4 height 

 of spine; body deep and ovate; depth 2.3 to 

 27 in standard length; caudal peduncle de- 

 cidedly more than half as deep as long; tips 

 of caudal fin broadly rounded; interorbital 

 with median pair of ridges inconspicuous; 

 most conspicuous element of color pattern 

 consisting of pale wedge (more or less dis- 

 rupted) below first dorsal; anterior parts 

 usually heavily spotted with orange, brown 

 in preserved specimens; opercular blotch 

 merely dusky ; cheek stripes pale ; no oblique 

 bands on pectoral fin; no blackish spots on 

 pectoral or caudal fin rays, these spots may 

 occur on base of pectorals ; no dark-bordered 

 light streak along lateral line posteriorly; 

 size large, to 20 inches. Range : Sitka, Alas- 

 ka to Monterey, California, in moderate 

 depths. Marine. Common. 



Speckled or Brown Rockfish. Orange-spot- 

 ted Rockfish 



204. Sebastodes maliger (Jordan and Gilbert) 



26b. Interorbital deeply concave ; the orbital rims 

 greatly thickened, and sharply elevated, 

 abruptly entering profile ; 4 posterior inter- 

 spinal membranes of dorsal scarcely incised ; 

 body deep and ovate; depth 2.3 to 2.75 in 

 standard length; size medium; rarely ex- 

 ceeding 12 inches.
