trals black band or line extends forward below second dorsal. Lower 

 black area of tail extends along close above subcaudal lobe short 

 space. Fins all -pale or dull brown. Caudal dark terminally. Iris 

 slaty. 



Natal, East Indies, Philippines, Japan. Known by its denticulate 

 scales forming longitudinal ridges over the upper surface of the body. 

 None of my material seems to show a condition of probably becom- 

 ing "uniform black with age" as Garman suggests. Some specimens 

 have the markings less contrasted, though this doubtless in a measure 

 the result of preservation.
