A small patch of melano- 

 phores is present on the anal 

 finfold immediately posterior to 

 the anus. This small patch of 

 pigmentation is a useful char- 

 acter which persists until 

 postflexion when it migrates dor- 

 sally with the receding finfold 

 to form the bar between the first 

 and second body bands (Fig. 5D). 

 A large triangular-shaped patch 

 of pigment is present at midbody 

 and extends nearly to the finfold 

 margin in preflexion and early 

 flexion larvae. The large trian- 

 gular-shaped patch expands ven- 

 trally to the finfold margin and 

 becomes more rectangular 

 shaped in late flexion larvae. 

 This is the only pigmentation 

 present on the anal fin in 

 postflexion larvae and juveniles 

 (Fig. 5, C and D). Two additional 

 patches of melanophores are 

 present on the anal finfold in 

 preflexion larvae. These form a 

 nearly continuous region of pig- 

 mentation which begins at ap- 

 proximately two-thirds of the 

 distance between the anus and 

 notochord tip which extends to 

 the caudal finfold. This pigmen- 

 tation breaks apart in late 

 flexion larvae and disappears as 

 the finfold recedes in postflexion 

 larvae. 



The posteriormost dorsal and 

 anal finfold pigmentation con- 

 nect and are continuous with a 

 large semicircular patch of mel- 

 anophores which covers nearly
