Anal spines: 0; Anal soft rays: 10 - 13; Vertebrae:
40 - 42. Diagnosis: tooth patches narrow; horizontally
based pectoral fins, placed low on the body; snout
sharply narrowed rostrally; 40-42 vertebrae; 7-29
gill-rakers; 11-12 anal-fin rays; caudal saddle and
bar pattern very faintly expressed; 7-8 branched caudal-fin
rays; body finely spotted; lateral line complete.
Head depressed; snout and tooth patches narrow; bodymore
or less fusiform; 17-18 abdominal vertebrae;
23-25 caudal vertebrae; 19 caudal-fin rays (arrangement:
ii-7-8-ii) (Ref. 44050). Colouration:
Bicolored, occasionally sharply so; dorsum tan or
light brown, venter pale and largely unpigmented,
except for slight stippling on the underside of the
head and around anal and pelvic fin bases, and scattered
small spots; flank and dorsum well marked with generally
small spots, 1-1.5 times an eye diameter large
or smaller, with sometimes larger blotches posteriad;
pectoral fin unspotted, rays may be dusky in adults;
pelvic fin generally opaque, unspotted; adipose with
pale distal margin, otherwise marked as dorsum; anal
fin matches body ground color, lightly spotted in
adults, with a pale distal margin in juveniles and
adults; distal 2/3 of caudal fin dusky in juveniles
and young, bounded by a clear distal margin and pale
basal crescent; caudal fin in adults matches dorsum
and flank ground colour, except for a clear distal
margin, and is well marked with fine spots in large
adults (larger than 40cm SL); caudal saddle and bar
pattern weakly developed, even in young; saddle slightly
darker than ground colour and extends to about mid- depth;
pale interspace slightly lighter than ground colour;
caudal bar somewhat darker than saddle and present
