Heavy pigmentation on midbrain and nape and pigment on tips of jaws; composition and arrangement of pigment series on dorsal and ventral margins of tail (progressive enlargement of dorsal series); caudal melanophore. Pigmentation: Preflexion: initially, 0-4 (usually 1-2) on midbrain, 0-3 on nape, dorsolaterally on gut, 14-20 in series on ventral margin of tail (from postanal myomere 3-4 to 18-20), 0-2 on dorsal margin of tail, and 1 below notochord in caudal region; by 5.8 mm, midbrain and nape covered, on tips of upper and lower jaws, at otic region, ventrally and laterally on gut, on inner surface of pectoral fin base, on pectoral fin blade (heaviest at distal margin with clear zone dorsally in middle of blade), 7-16 on dorsal margin extending anteriad to about postanal myomere 7-8. |
