 TalBE 2. — Measurements (millimeters) of larval Pseudopleuronectes americanus. Specimens above dashed line are yolk-sac larvae. 



again in flexion larvae by =6.4 mm. Scattered 

 melanophores appear on the anal fin fold at 3.6 

 mm, and a few appear at the center of the dorsal fin 

 fold at =4.2 mm. These melanophores remain 

 through the larval period with pigment bars, 

 characteristic of juveniles, developing on the dor- 



sal and anal fins in flexion and postflexion larvae 

 >7.3 mm. By 4.4 mm a few melanophores appear 

 on the fin fold at about the notochord flexion point. 

 These melanophores increase in number with de- 

 velopment and are visible on the caudal fin during 

 and after development of the caudal fin rays.
