Diagnosis. — D X,12; P 18; A III,7; gill rakers 20-21 total, 14 or 15 on lower limb; lateral¬ 
line scales 46-52; circumpeduncular scales 32-34; scales below origin of first dorsal fin 5. Anteri¬ 
or nostril a simple tube lacking cirri or flaps. Snout about equal to or less than orbit diameter; upper 
jaw extends to below midorbit. Body depth about 3.5^1.0 into SL; head about 2.5-2.7 into SL. 
Caudal fin emarginate. Six broad brown bands on body: one on nape, four below dorsal fin, one on 
caudal peduncle; color overall buff, paler below; fins faintly yellow, without prominent markings. 
Description (partially adapted from Boulenger 1895:289 and Heemstra and Anderson 
2016:2412).— Body compressed, width across pectoral fm bases about 2.1-2.3 in HL; depth about 
3.1-4.0 times in SL; head about 2.6 in SL. Dorsal and ventral profiles gently curved; snout point¬ 
ed and equal to or longer than diameter of orbit, which goes 3.3-3.8 times in HL; fleshy interor¬ 
bital width 1.3-1.6 times into orbit diameter. Lower jaw slightly projecting beyond upper jaw; 
maxilla extending to below middle of orbit. Anterior nostril with low anterior rim and short flap- 
like posterior rim without fringes. Posterior nostril lacking rim. Opercular spines three, middle 
spine well developed, upper and lower spines rudimentary. Preopercular margins finely serrated. 
A broad tapered band of small pointed premaxilla teeth, flanked by outer series of spaced 
slightly enlarged teeth; a few enlarged teeth at anterior end along inner edge of band. Dentary teeth 
in single series laterally and a cluster of teeth at anterior end. Vomerine teeth in a V-shaped band; 
palatine teeth in a single series. 
Scales large, ctenoid and present on all of body and most of head, but absent on lower jaws, 
gular and branchiostegal membranes, snout, top of head, anterior half of suborbital region, and a 
narrow naked strip along outer margin of preopercle; opercle, subopercle, and interopercle scaly, 
the scales in six to eight series on cheek. Scales absent on fins except near base of pectoral and cau¬ 
dal fins. 
Dorsal fin originating above base of pectoral fin; spines increasing in size to the 4 th through 
6 th spines, which are slightly short of half length of head, and exceeding longest soft rays; a notch 
between spinous and soft portions of fm. Pectoral fm obtusely pointed, somewhat longer than 
pelvic fm, its length about 75% of HL. Second anal spine about equal to or slightly shorter but 
stronger than 3 rd spine. Caudal fm feebly emarginate. 
Color (based on photograph of fresh specimen from St. Helena in Fig. 22): Body light buff to 
pale greenish-yellow becoming whitish ventrally; six brown bands or vertical blotches, the first
