length. Maxillary beyond front eye edge, not to pupil. Lips rather 

 broad, firm. Teeth fine, in villiform bands in jaws. Nostrils to- 

 gether, close before upper front of eye. Interorbital level or only 

 very slight median concavity. Preorbital and preopercle edges entire. 

 Rakers, 5 or 6 + 8 or 9 short points, nearly one-third of filaments; 

 latter 2h in eye. Pseudobranchiae little less than filaments. Pre- 

 maxillary groove on top of head entirely scaleless, also maxillary, 

 preorbital and snout tip. Hind part of premaxillary groove never 

 entirely shut off by lateral intrusion of scales. Scales finely ciliated, 

 with about five basal striae. Suprascapula entire. Lateral line 

 concurrent with back to caudal base medially; simple tubes well 

 exposed. Spinous dorsal inserted nearly midway between eye center 

 and soft dorsal origin; slightly more advanced in young; third spine, 

 l-f to 1^^ in head. Anal inserted little behind soft dorsal origin; 

 third spine longest or trifle longer than second; 2 J to 2f in head. 

 Caudal well forked, trifle less than head ; pectoral, 1-^ to 1§ ; ventral, 

 If to If. Color in alcohol silvery-wdiite generally; back pale 

 brownish. Iris white. Fins all very pale brown; end of spinous 

 dorsal lobe black with white bar below, and midway on fin still 

 lower pale dusky horizontal streak. Seven examples, 47 to 108 mm. 

 Bleeker does not show ^ the whitish band below the black apical 

 blotch at front of spinous dorsal, nor mention if in his text. His 

 example was 97 mm. long.

Head, 2^ to 2^; depth. If to If; D. XI, 23; A. HI, 18; scales, 

 43 to 45 from shoulder in nearly median series to caudal base medi- 

 ally; about 40 or 41 tubes in lateral line; 7 scales above lateral line 

 to spinous dorsal origin, about 4 to soft dorsal origin, and 22 or 23 

 below to spinous anal origin; snout, 3 to 3§ in head; eye, 2| to 3; 

 maxillary, 3§ to 3|; interorbital, 3f to 3^. Back well elevated; 

 body strongly compressed; predorsal slightly trenchant. Caudal 

 peduncle strongly compressed; length about three-fifths its least 

 depth and latter, 2J in head. Head width half its length. Snout 

 conic, length about seven-eighths its width. Eye elevated, advanced, 

 or hind pupil edge about midway in head length. Small mouth 

 terminal, closed jaws even. Maxillary largely below preorbital, to
