 in the reared larvae. 



Pigmentation 



Pigment in the larvae at hatching is restricted to 

 the postanal ventral midline, the ventral abdominal 

 surface, the dorsoposterior peritoneum, the anus, 

 and the lower jav^ angle (Fig. 2 A). The postanal ven- 

 tral midline melanophores are positioned in a single 



row, number from 25 to 37 in yolk-sac larvae and 

 increase to a maximum of 63 in larvae 3.5-4.0 mm 

 in length. These melanophores decrease to a mini- 

 mum of 25 in larvae 5.5 mm or larger. The ventral
