Depth iHtol^yi; head 2 3^ to S}i, width 2K to 2}i. Snout 2i^ 

 to 2^ in head from snout tip; eye 33^ to 5)4, IK to 2V^ in snout, 

 slightly greater than interorbital in young to 1^ with age; maxillary 

 % to ^ in snout, 3)4 to 33^ in head; interorbital 3% to 4, broadly 

 convex. Gill rakers 3 + 12, short points, % of gill filaments, which 

 equal e3''e. 



Scales 26 or 27 between gill opening and caudal base; tubes 17 to 

 26 in lateral line; 6 or 7 scales above lateral line, 15 or 16 below. 

 Scales with 8 to 24 basal striae, largely marginal with age; apical 

 denticles 75 to 320, basal elements in 1 to 16 transverse series; circuli 

 very fine. 



D. XII, 25, I to 28, 1, last spine 1^ to 23^8 in total head length, 

 fifteenth ray 1% to 1%; A. Ill, 20, i or 21, i, thu'd spine IJ^ to 2)^, 

 thirteenth ray 1% to 1,4^; least depth of caudal peduncle SJ/g to 3%; 

 caudal with hind edge slightly convex, IJ^ to 1%; pectoral 1% to 

 1^; ventral 1^ to 1^. 



Dull brownish generally, lighter below. Broad blackish-brown 

 ocular band from middle of predorsal down to eye which equal in 

 width, narrowing below down over cheek; wdth age an interorbital 

 juncture forms leaving pale spot over eye medially and band much 

 broader, extending over front of opercle. Blackish-brown crescent 

 forms in young along soft dorsal base and over front of caudal pedun- 

 cle, intersected vertically by pale bar or ill-defined band just before 

 caudal peduncle and extending into bases of both soft dorsal and soft 

 anal posteriorly; with age pale band disappears and dark crescent 

 becomes perfected. From base of spinous dorsal and lower edge of 

 dark crescent on soft dorsal about 18 or 19 dark lines extend down,
