Rostro-dorsal profile nearly straight; head pointed. Height 

 3.4 to 4; head somewhat more or less than thrice in length. 

 Eye 3.2 to 3.7 in head, its diameter nearly equal to or greater 

 than snout, 1.4 to 1.7 in postorbital part of head and I to 

 1.4 in interorbital space, which is flat and goes 2.7 to more 

 than thrice in length of head. Maxillary extending to vertical 

 through between nostrils or somewhat farther. Origin of dorsal 

 conspicuously nearer to head than to base of caudal, opposite 

 to 1 5th or i6th lateral scale and separated by 25 to 26 praedorsal 

 scales from snout. The produced middle rays of dorsal nearly 

 reaching caudal. Anal with a basal sheath of one (or two) 

 irregular series of scales, its penultimate rays in old specimens 

 strongly produced, reaching near end of caudal, the middle 

 rays of which are prolonged. Pectorals about equal to head 

 without snout. Height of caudal peduncle at base of caudal 

 about twice in length of head. Brown, ventrally lighter. A 

 dark longitudinal band from snout, through eye running above 

 pectoral to caudal, a lower band beginning on head and running 

 below pectoral to caudal; both unite in a round blotch at 

 base of caudal. A few black points on anal and caudal. Other- 

 wise fins dusky. Length 82 mm. [Type in the British Museum
