 or 10 (usually 10); pectorals ii,16 to 19 (usually 17 or 18); transverse 

 scale rows from upper edge of gill opening to base of caudal rays 24 

 to 27, with 2 between lateral line and origin of dorsal, 9 between 

 lateral line and origin of anal; dorsal lateral line with 15 or 16 tubular 

 scales; gill rakers 6 to 9 + 1 + 19 to 22, totaling 28 to 31. 



Depth of body 2.0 to 2.2; length of head 3.1 to 3.6; both in standard 

 length. Snout 3.5 to 4.0; eye 2.8 to 3.3; preorbital width 7.0 to 8.0; 

 length of upper jaw 2.5 to 2.9; postorbital part of head (hind margin 

 of eye to upper edge of gill opening) 2.2 to 2.5; interorbital width 2.9 

 to 3.1; depth of caudal peduncle 2.0 to 2.3; length of pectoral fin 1.2 

 to 1.3, of pelvic fin 1.2 to 1.3, of second dorsal spine 2.0 to 2.3, of upper 

 caudal rays 0.6 to 1.0, of lower caudal rays 0.7 to 0.9, all in length of 

 head (tip of snout to posterior margin of opercular membrane). 

 Depth of caudal peduncle in its length 1.1 to 1.4; angle of upper 

 profile with lengthwise axis of body 33 to 48 degrees, profile straight 

 to convex. 



Teeth of jaws conical, widely spaced, an outer row of enlarged teeth, 

 in lower jaw projecting anteriorly near symphysis, a few teeth at 

 sides near tip of lower jaw curve out iDosteriorly ; inner teeth minute 

 and in single row in upper jaws, forming small patches of very minute 

 teeth on either side of symphysis in lower jaw; snout scaled to tip, 

 line from eye, including nostril and along upper edge of preorbital, 

 naked; pre- and sub-orbitals scaled, lower margin of latter almost 

 entirely obscured; preopercle produced at angle, its posterior margin 

 entire with some irregular crenulations observable at angle in many 

 specimens; no scales on bases of soft dorsal and anal; upper and lower 

 caudal rays filamentous, 3 free spines on upper and lower caudal base; 

 profile angle, measured with one side of angle lying along closed 

 lower jaw to tip of snout and the other side from snout to nape 

 directly above gill opening, 80 to 96 degrees. 



Color in alcohol. — Head and upper half of body bluish gray to brown ; 

 lower sides and belly lighter, pale to silvery; a narrow dark to bluish 

 line from eye along naked area just under nostril toward middle of 

 snout; iris faintly bluish; spiny dorsal membrane more or less dusky, 

 this sometimes accentuated basally and distally, spines dusky; lips, 

 especially at tips of jaws, dusky to black; soft dorsal and anal rays 

 dusky, membranes lighter; upper and lower caudal rays brownish, 

 middle rays dusky basally, pale distally; pelvics pale to dusky; pec- 

 torals pale except at base, where upper rays are dusky to blackish, 

 axil of pectoral with large black blotch, this broadest on dorsal por- 

 tion and usually not extending to lower rays; in young of less than 

 40 mm. standard length axU of pectoral dusky to black,
