Fig. 4C). Few melanophores usually form along lower 

 jaw after about 7 mm. 



Soon after hatching, a row of melanophores forms 

 along horizontal septum, originating just behind 

 midtail and spreading cephalad and caudad (prima- 

 rily cephalad) along tail (Fig. 2, A and B). Barred 

 pattern begins to develop at about 6 mm as melano- 

 phores spread upward from pelvic-fin bases and from 

 ventral margins of last three or four preanal 

 myomeres (Fig. 2B). Two more bars begin to spread 

 upward from vicinity of anal-fin rays 5-8 and from 

 midwaj' between pectoral- and pelvic-fin bases (Figs. 

 2C, 3A) between about 8 and 9 mm. Bars usually do 

 not reach dorsal margin in larvae. Pigmentation on 



pectoral-fin base sparse until about 8 mm then in- 

 creases, spreads onto adjacent myomeres, and in ju- 

 veniles merges with melanophores spreading down- 

 ward from dorsum to form saddle (Figs. 2C; 3, A and 

 B). Melanophore cluster on hypural area expands to 

 cover almost entire area by about 13 mm. Juveniles 

 thus display six or seven bars (including pectoral 

 saddle); in juveniles >30-40 mm posterior three or 

 four bars most prominent (Fig. 3B). 



Pectoral-fin pigmentation initially sparse. After 

 hatching, melanophores gradually spread over mem- 

 branes between upper 5-6 rays, a few scattered be- 

 tween all but lowermost 3-4 rays, by about 8 mm 

 (Fig. 2, A-C). Pigment patterns variable in lai-vae
