Head 2f ; depth 3f ; D. VI — 8, i; A. I, 8, i; scales 42 in median lateral 

 series to caudal base and 6 more on latter; 14 scales transversely 

 between soft dorsal and anal origins; about 38 ? predorsal scales; 

 head width If its length; third dorsal spine 2f ; sixth dorsal ray 1|; 

 seventh anal ray 2; least depth of caudal peduncle 2^; pectoral If; 

 ventral 1|; snout 4| in head measured from upper jaw tip; eye 5j; 

 maxillary 2|; interorbital 3j. Body well compressed, contour slen- 

 derly ellipsoid. Caudal peduncle strongly compressed, slightly 

 longer than deep. Head robust, muzzle obtuse. Snout convex, 

 length I its width. Eye small, elongate, center near first third in 

 head. Mouth oblique, large, lower jaw well protruded. Maxillary 

 reaches about center of eye. Teeth fine, in bands in jaws. Tongue 

 broad, depressed, free. Interorbital slightly depressed in front, 

 slightly convex. Preopercle with strong obscure spine, directed 

 downwards. Rakers 6 low knob-like rudiments on lower limb of 

 first arch. Head scaly, except muzzle. Scales small and crowded 

 on predorsal. About 12 rows of fine scales across cheek. From 

 lower eye edge 6 cutaneous ridges radiate down over infraorbital. 

 On head, predorsal, breast and belly scales cycloid, on trunk ctenoid, 

 and also larger on latter behind. Caudal and pectoral bases with 

 small scales, fins otherwise naked. No trace of 1. 1. Dorsal spines 

 thin, fin inserted slightly nearer snout tip than caudal base, third 

 spine longest, reaches back slightly beyond soft dorsal origin. Last 

 little nearer caudal base than hind preopercle edge, rays gradually 

 higher towards last, not quite reaching caudal base. Anal opposite 

 soft dorsal, similar. Caudal rounded, median rays longest. Pectoral 

 broad, median rays longest, reaches vent. Ventral inserted slightly 

 before pectoral origin, reaches | to anal, with small papilla. Color 

 in alcohol dull uniform brownish generally. Dusky brown to black- 

 ish line from hind eye edge horizontally back to opercle above, two 

 obliquely down from lower hind edge, and another more obscurely 

 vertically down over infraorbital. Fins all finely barred with narrow 

 dusky-brown lines. Black blotch, little smaller than pupil, just 

 before pectoral origin. Iris slaty. Length 80 mm. (caudal tip
