eaching halfway to middle of anal fin base. Pelvic<br />

fin pointed, first ray longest, reaching halfway<br />

to anal fin origin.<br />

Dorsal fin naked in all specimens to 152 mm<br />

SL, in larger specimens sparsely scaled on proximal<br />

| of soft portion, with single row of scales<br />

along anterior and posterior margin of rays. Anal<br />

fin densely scaled anteriorly in adults, on proximal<br />

half or less in specimens up to 152 mm SL.<br />

Caudal fin densely scaled, in adults scales covering<br />

almost all of fin except posterior margin and<br />

middle interradial membrane. Pelvic fin naked<br />

in young, progressively densely scaled on both<br />

sides along anterior margin. Pectoral fin scaled<br />

basally in specimens over 200 mm SL.<br />

Colouration in preservative. Smallest specimens,<br />

about 60-80 mm SL (Fig. 37) with dark brown to<br />

blackish lateral band from cleithrum to caudal fin<br />

base. White, partly contiguous spots bordering<br />

lateral band dorsally and ventrally; additional<br />

one or two rows of indistinct light spots on dorsum<br />

dorsal to lateral line. Short, narrow, dark<br />

brown vertical bars 1-3 (in one specimen indicated<br />

bar 4) from about lateral line, fading on<br />

abdominal side; expanded into oval or round<br />

blotch where crossing lateral band. Dark brown<br />

blotch immediately posterior to orbit and dark<br />

brown horizontal stripe dorsally on opercle.<br />

Dorsal fin dusky, both spinous and soft portion<br />

with large white or hyaline spots. Anal fin whitish<br />

anteriorly, colourless posteriorly. Black caudal<br />

blotch, small, rounded, contiguous with lateral<br />

band, and extended by blackish stripe along † of<br />

middle of caudal fin; blotch midbasal in 64.2 mm<br />

SL specimen, slightly superior in remainder. Rest<br />

of caudal fin grey with large white spots on dorsal<br />

half. Pelvic fin whitish.<br />

In specimens about 90 mm SL and larger (Figs.<br />

38-39) lateral band much less distinct than vertical<br />

bars/blotches and gradually transformed to<br />

narrow stripe. Dorsum, nape and snout brown<br />

with yellow spots on top of snout, nape and in<br />

two rows on dorsum close to dorsal fin. Side of<br />

head light brownish, ventrally yellowish, large<br />

yellow spots in brownish area. A dark brown spot<br />

ventrally on opercle. Dark horizontal stripe from<br />

snout to orbit, from orbit horizontally across<br />

opercle, brownish and distinct. Stripe continued,<br />

indistinct, brownish, along middle of side, immediately<br />

above level of lower lateral line tube<br />

row, lighter anteriorly, to caudal fin base. Stripe<br />

crossed by three short vertical bars confined to<br />

middle third of side, containing an approximately<br />

round dark brown blotch at intersection.<br />

Large light spots in a row dorsally and ventrally<br />

along horizontal band; an irregular row of large<br />

light spots on dorsal side, another along abdominal<br />

side. Dorsal fin brown, spinous portion<br />

with two, soft portion with three rows of large<br />

hyaline spots. Anal fin hyaline, pelvic fin smoky<br />

on both sides.<br />

Large adult male, 330 mm SL (Fig. 40) with<br />

dark brown back, nape and snout dorsally,<br />

lighter brown side, chest yellowish white, abdomen<br />

dirty white, ventral aspect of caudal peduncle<br />

duskied. Side of head brown. Lower jaw grey,<br />

chest and throat dusky on white ground (unique<br />

for this specimen). Row of irregularly arranged<br />

black spot in horizontal succession from orbit to<br />

posterior margin of opercle, scattered black spots<br />

on opercle. Extrascapular series marked by a black<br />

oblique stripe. Spinous dorsal fin brown, soft<br />

portion brown with seven cross-rows of lighter<br />

spots and grey distal margin. Anal fin brown,<br />

darker distally. Caudal fin brown with about 10<br />

vertical rows of lighter spots on dorsal lobe. Pelvic<br />

fin dark brown on posterior side, grey on<br />

anterior side. Pectoral fin greyish.<br />

Indistinct dark vertical bars (bars 2-3) containing<br />

distinct irregular black blotches at level slightly<br />

above upper lateral line. Anteriorly on side, above<br />

pectoral fin, a large black blotch. Side close to<br />

major black blotches partially, especially anterior<br />

blotch, slightly lighter than rest of side. Caudad<br />

from cleithrum an irregular row of irregularly<br />

shaped black spots connecting major black blotches,<br />

continued beyond posterior blotch as gradually<br />

narrower band of blotches to about middle<br />

of caudal peduncle. Numerous irregularly arranged<br />

and irregularly shaped black blotches on lower<br />

side associated with bars 2 and 3, on pectoral fin<br />

base and under adpressed pect oral fin. Caudal<br />

blotch slightly elongate, margined by narrow<br />

silvery circle; on both sides of fin also minute<br />

dark spot dorsally on ventral lobe, margined by<br />

light spots. Other large males similarly dark with<br />

dark brown to black spinous dorsal fin and black<br />

spots on anterior abdominal side. Lower jaw,<br />

throat and branchiostegal membrane whitish or<br />

yellowish without blackish pigmentation.<br />

Breeding female, 207 mm SL (Fig. 41) similar<br />

to male, but anterior two blotches brown, posterior<br />

blotch black and most prominent. Five series<br />

of light spots in dorsal fin. Only some indistinct<br />

brownish markings on abdominal side. No light
