Upper branch of lateral line usually terminates a little in advance of end of dorsal fin, but may extend full length of fin; terminal canal bearing scales often descend a scale row, canal then continuing for another 2(-3) scales; dorsal and ventral branches of lateral line on caudal fin well developed and extending almost to fin periphery; median branch usually well developed, but rarely extending much beyond 2/3 of caudal fin length; dorsal fin spines increase gradually in length to (5th) 6th-7th and are then more or less equal in length; anal fin rounded; pectoral fins rather short, rarely reaching beyond level of vent; first branched pelvic ray somewhat produced but rarely markedly filamentous; caudal fin slightly emarginate and usually heavily scaled almost to fin periphery (Ref. 52346). Coloration: pearl grey and greenish above in more or less longitudinal stripes, whitish below, silvery troughout; scales of caudal peduncle and flank in larger individuals ringed in dark brown pigment, resulting in a series of longitudinal striations passing along scale rows; longitudinal striping most pronounced on caudal peduncle and dorsum; vertical stripes less prominent in adults and completely absent in specimens of 15cm SL (Ref. 52346). Dorsal fin transparent grey with bright blue reflections on spines and brownish-red longitudinal markings; caudal fin greyish edged with red on lower half (Ref. 52307, 52346). Pectoral fins transparent grey; pelvic and anal fins pale blue-grey (Ref. 52307, 52346), former with red markings anteriorly (Ref. 52346). Anal fin of mature male fish smoky brown with a few rows of pale non-ocellate maculae that are typically lacking in females; mature males exhibit caudal fin striping and spotting; top of head in front of eyes dark grey; gill covers yellowish and an area behind head dusky yellowish grey; some red markings between pelvic and pectoral fins (Ref. 52346). Preserved juveniles: strong nape stripe separated from dark opercular blotch; 7-8 thick vertical strips which extend down onto flank well below midline, often almost to ventrum; juvenile barring usually pronounced in specimens of less than 6-7cm SL; dorsal fin dark grey brown and spotted with numerous rows of non-ocellate pale maculae (Ref. 52346).
