ternal pigment is present in the nape region al- 

 though the dorsal midline is pigmentless. A few 

 large stellate melanophores extend laterally from 

 the nape to the gut cavity. A series of 10 or 11 

 distinct melanophores is visible along the ventral 

 midline of the tail, the anterior five of which are 

 embedded in musculature dorsal to the developing 

 anal fin. A few small melanophores may be pres- 

 ent on the notochord tip. The pectoral fins are 

 distinctively and heavily pigmented. A dense con- 

 centration of melanophores occurs on the proximal 

 surface of the fin base but the distal surface is 

 unpigmented. Elongate melanophores line the 

 inner and outer surfaces of the fin blades creating 



a striated appearance. The developing pelvic fins 

 are also pigmented. 



As larvae develop, pigment increases on the 

 head over the brain. Melanophores persist along 

 the tip of the lower jaw and the anteroventral 

 margin of the maxillary. Several melanophores 

 develop around the bases of the posttemporal and 

 supracleithral spines in larvae >10.5 mm and on 

 the dorsal part of the operculum anterior to the 

 opercular spines in larvae >13.5 mm. 



Pigmentation within the gut cavity remains in- 

 tense through larval development and external 

 melanophores remain scattered on the body wall 

 over the gut. In larvae -10.5 mm, as dorsal fin
