Two examples, larger 13 inches in length. This species is related to Epin- 

 eph'ehis praiopercularis (Boulenger).' It differs in the absence of black dots or spots 

 on upper surface, fewer gill-rakers, fewer lateral pores, vertical fins without a nar- 

 row whitish margin. Lower brown streak across preopercle also characteristic of 

 E. heniochus.
