Rostro-dorsal profile more or less convex. Head pointed. Eye 

 3 — 3.4 in head; its diameter conspicuously longer than snout, 

 3 — 3.4 in postorbital part of head and equal to or somewhat 

 shorter than the flat interorbital space. Maxillary extending 

 about to vertical through posterior nostril. Origin of dorsal 

 usually nearer to head than to base of caudal, opposite to 

 14th — 15th lateral scale and separated by 20 — 24 praedorsal 

 scales from snout. Second or third penultimate rays more or 

 less produced and then reaching root of caudal. Anal with a 

 low basal sheath of one series or two irregular series of scales; its 

 posterior rays preceding the last more or less produced, reaching 

 on anterior third of caudal. Caudal rounded or pointed, the 

 middle rays being produced. Pectorals rounded, 1.6 — 1,7 in 

 length of head. Height of caudal peduncle at base of caudal 

 1.7 — 2 in length of head. Colour variable. Yellowish to lighter 

 or darker brown. Back darker. Belly often reddish. According 

 to state of preservation, sexual maturity and probably also 

 locality the colouration is influenced. There are always present 

 3 dark longitudinal stripes, sometimes produced by black edges
