anus and the ventral fins is blackish, but the region anterior to the 

 ventrals is usually dark brown (or light brown). The usual round- 

 ish spot above and behind the pectoral fin covers about seven oblique 

 scale rows, and is ocellated with a lighter ring, which is preceded by 

 an indistinctly darker squarish saddle just before the first dorsal fin, 

 and followed by a similar saddle extending below the interdorsal 

 space. Silvery reflections are seen on the sides of the head and body. 

 The coloration of the head in general is light, becoming dark brown 

 near the anterolateral angles of the snout, and olackish on the 

 opercle. The buccal cavity is lined with purplish brown, without 

 light margins about the gape; the branchial cavity is lined with 

 brownish black, with a narrow light margin along the free edge of 

 the opercular and branchiostegal membranes. The vertical fins are 

 blackish, varying to light dusky; pectorals, light dusky; ventrals 

 blackish, with a white filament. In the young the first dorsal may 

 be whitish proximally, but black on the tips of the spine and the 

 front rays. The tail of the young is crossed by bars which are wider 

 than the light interspaces between them.
