form in some specimens by 12.0 mm and was visible in 

 most specimens by 14.0 mm (Fig. IB). Snout pigment 

 was represented by one or four melanophores. Anterior 

 lower jaw pigment was heavy and confined to the tip 

 of the jaw. 



By 17.5 mm, the dorsal midline pigment had become 

 much darker and denser (Fig. IC, Table 4) and extended 

 from the caudal fin to the head region, except for a gap 

 where the nape pigment was beginning to form. All 

 fins were unpigmented. Pigment along the ventral body 



midline began to form at 17.5 mm, with a few postanal 

 melanophores. Lateral midline pigment formed in two 

 locations. Melanophores near the peduncle increased 

 anteriorly, and pigment began forming dorsal to the gut 

 cavity and increased posteriorly toward the peduncle. 

 A body bar began to form on the lateral surface above 

 the pectoral fin between the spinous dorsal fin and the 

 anterior lateral midline pigment. Opercular, eye, and 

 head pigment all increased in density. Melanophores on 

 the snout also became more prevalent between the tip of
