Olive brown above, mottled and spotted with blackish; whitish be- 

 low; a narrow dark streak along the lateral line, with a broader one 

 below it, which terminates behind in a series of spots and blotches; 

 lower jaw and branchiostegal membranes sometimes bright orange-yel-

 ous transverse dark lines; membrane of spinous dorsal with a black

 blotches at base; ventrals and anal orange; pectoral appendages slen- 

 der, dusky. Gill-rakers rather long and slender, 15 below angle; band 

 of palatine teeth wide, shorter than eye; spines on head moderate in 

 size, compressed, the one at upper posterior angle of orbit little devel-
