Depth \% to \y^; head 3^ to 3%, width 1% to 2. Snout 2 to 

 2J^ in head from upper jaw tip; eye 2J^ to b}/^, l}i to 2% in snout, 

 1 to 1^ in interorbital; maxillary extends about % in snout length, 

 in small examples to point about % or opposite front nostril, 33^ to 

 35-^ in head; interorbital 3 to 3%, broadly convex; preopercle spine 

 along inner edge 2% to 4. Gill rakers 5+13, short, obtuse points 

 about 3^ of gill filaments, which equal eye. 



Scales 50 to 63 counted along and above lateral line to caudal base; 

 tubular scales 50 to 52; 7 or 8 scales above lateral line, 25 or 26 below. 

 Scales with 7 basal radiating striae, obsolete with age; apical denticles 

 50 to 87, each with long slender root; circuli fine, strong. 



D. XIII, 19, 1 or 20, i, last spine 1}^ to 1}^ in total head length, 

 seventh ray S}/^ to 33^ in combined head and body; A. Ill, 18, i or 

 19, 1, third spine 1}4. to 23^ in total head, ninth ray 1 1^ to 13^6; least 

 depth of caudal peduncle 2 to 2^ ; caudal convex behind, lli to l^s ; 

 pectoral Iyo to 1J4', ventral 23^ to 2% in combined head and body. 



Generally dull brown, with six dusky brown vertical bands, slightly 

 arched forward and second, fourth, and sixth slightly wider. Each 

 scale on body with round dark blue spot. Pale or buff transverse 

 band from close before dorsal down to hind eye edge and variably as 

 low as base of preopercle spine. On head and chest dark blue spots 

 few and scattered, though traces of many smaller pale blue ones. 

 Iris brown. Edges of vertical fins all narrowly blue with dark sub- 

 marginal line; soft fins all closely spotted with blue. Paired fins dark 

 or dusky brown, inner ventral raj^s paler. 



East Indian region, previously largely known from a few of the East 

 Indies, Queensland and Singapore. Variably the coloration changes 

 with age. Our small examples show the white band on the head 

 extended below on the side of the breast, sometimes nearly to the 

 ventral origin wiiere they meet. Also sometimes 2 or 3 transverse 

 blue lines from last dorsal rays down over caudal peduncle to last 

 anal rays. The smallest examples also have 2 transverse blue lines 

 on the caudal basally followed by a single blue spot posteriorly. 

 They also have but few blue spots on soft dorsal and anal, though in 

 addition a blue median frontal line and 2 blue lines on the muzzle,
