line; spinous dorsal ashy, the first 3 sj)ines black on the middle portion, 
the other splines dark, hut not so distinctly so; tips of last few spines 
dark; soft dorsal light brownish or grayish, crossed near the base by a

of orbit, in the larger scales, the free gill-membranes, and in the smooth 
preopercle.
