Dorsal fin origin situated about two-thirds of standard length from snout, obliquely orientated, anteriorly higher and posteriorly lower, distal margin crescentic with anterior two or three rays longer than posterior rays, and 21-25 rays (Ref. 91771). Anal fin longer than dorsal fin, opposite dorsal fin with slightly more anterior origin, obliquely orientated, anteriorly lower and posteriorly higher, anterior 10 or so rays longer than posterior ones, especially in males where they also disappearstronger, margin broadly rounded, rays posterior to first 10 with distal margin straight, 26-30 rays (Ref. 91771). Scales cycloid with reticulate striae, scales extending anteriorly to operculum and pelvic fins; 37-39 scales in lateral series; scales on caudal peduncle circumference, 12 (Ref. 91771). Caudal peduncle slender, subcylindrical entire length, 18-21.5% of standard length (Ref. 91771).Colour: In life it is grey-silver, underside lighter, paired fins light and transparent (Ref. 91771). It is light brown coloured in preservation (Ref. 91771). Kramer, B., R. Bills, P. Skelton and M.
