D.45-55. A.28-36. L.I. 60-70. L.tr.4J-6/13-llor5|-S4/13-ll. 

 Length of head from 4 to 5, of caudal fin 6 to 7|, height of body 

 7 to 7 1 in the total length. Eyes diameter 7 (5 in the young) in 

 length of head, 1 to 1| diam. from end of snout and also apart. 

 Greatest width of the head equals or of its length. Teeth 

 in numerous villiforin rows in jaws, vomer, and palate ; a poste- 

 rior row of about 12 large conical teeth on either ramus of man- 

 dible. Fins pectoral rather more than half as long as head, but 

 not reaching to above origin of anal ; ventral two thirds as long as 

 pectoral. Scfdes on summit of head of moderate size ; 16 rows 

 between snout and base of dorsal fin, 10 between eye and angle 

 of preopercle. Lateral line first passes along 16 or 18 rows of 

 scales, then descends for two rows, and subsequently passes direct 

 to centre of caudal. Colour varies with age and the water. Back 

 greyish green ; the immature with a brilliant orange band passing 

 Irom eye to middle of tail, in the more mature there are five or six 

 cloudy bands descending to below lateral line ; abdomen orange ; 

 on posterior third of body, on dorsal, anal, and caudal fins are
