The height of the body is contained once and three-foiirths in the 

 total length (the caudal fin not included) ; the width of the inter- 

 orbital space is more than that of the orbit ; the breadth of the infra- 

 orbital ring below the centre of the eye is one-half of the greatest 

 breadth of the prajorbital. The soft dorsal fin is produced into a 

 point, the third, fourth and fifth rays being the longest ; caudal fin 

 forked. Body with seven blackish cross-bands : the first is indistinct, 

 and descends obliquely from the nape to the orbit and praeoperculum ; 

 the second from the first and second dorsal spines to the axil of the 

 pectoral ; the third from the fifth dorsal spine towards the middle of 

 the ventral ; the fourth from the eighth and ninth dorsal spines 

 towards the vent ; the fifth from the two last dorsal spines to the 

 second of the anal fin ; the sixth from behind the middle of the soft 

 dorsal fin towards the end of the anal ; the seventh is indistinct, 

 across the tail.

The height of the body is rather more than one-half of the total 

 length (the caudal fiji not included) ; head a little higher than long. 

 The width of the intororbital space equals the extent of the snout, 

 and is rather more than the width of the orbit. The scales on the 

 upper surface of the head advance to the front margin of the eye. 

 The breadth of the infraorbital ring below the centre of the eye is one- 

 half of the greatest breadth of the praorbital. Teeth compressed, 

 very narrow, of moderate length. The soft dorsal and anal fins 

 angular ; caudal forked, with the lobes rounded. Body with six dark 

 cross-bands, which are narrower than the interspaces between them : 

 the first indistinct, from the nape to the operculum ; the second from 

 the two first dorsal spines to the base of the pectoral ; the third from 

 the fifth and sixth dorsal spines to behind the base of the ventral ; 

 the foxrrth from the tentli and eleventh dorsal spines to the vent ; the 

 fifth from the three anterior dorsal rays to the three anterior anal rays ; 

 the sixth across the tail, immediately behind the vertical fins.
