 terior to it. In the most advanced Stage 1 specimen 

 (Figure 8a) additional pigment occurs anterior to 

 the stomach. Stomach pigmentation is completed 

 by Stage 3 and during this stage new pigment sites 

 develop along the ventral margin of the orbit, in 



the opercular region, and along the predorsal crest. 

 Light abdominal pigmentation appears during 

 Stage 4 and the caudal pigment extends anteriorly 

 along the dorsum (Figure 8b), reaching the dorsal 

 fin base later in this stage. As development pro- 

 gresses, pigmentation spreads and intensifies
