present on the underside of the pectoral fin base. A 

 discrete melanophore is present at the articula- 

 tion of each of several dorsal fin rays near the 

 center of the soft dorsal fin. 



As larvae develop, pigment increases over the 

 brain. Melanophores are added on the snout, in- 

 terorbital region, tips of the upper and lower lips, 

 along the maxillary, and on the cheek and oper- 

 culum. Pigment increases around the orbit and 

 around the posttemporal spine, extending an- 

 teriorly over the head. Melanophores line the an- 

 terior margin of the cleithrum beneath the oper- 



culum. Pigment on the gut becomes less obvious as 

 body musculature increases. The dorsal body sur- 

 face is pigmented from nape to caudal peduncle by 

 —11 mm. Large stellate melanophores beneath the 

 soft dorsal fin increase in number and are aligned 

 along the muscles surrounding the dorsal 

 pterygiophores. This is the densest pigmentation 

 on larvae. Internal and external melanophores are 

 added along the body midline anteriorly from the 

 caudal peduncle forming a line along the 

 notochord which extends to the head by =16.5 mm. 

 Melanophores extend ventrolaterally from the
