 more or less distinctly with dusk}- just back of eye over the nuchial 

 region to lower edge of opercles. Ventral fins jet black and cover- 

 ing a dusky spot on belly. The three anterior dorsal and anal rays 

 each have a large black spot margined with yellowish. More or 

 less dusky on tip of spinous dorsal; otherwise fins yellowish white.
