above 30 mm. Pigment appears on the second 

 dorsal fin at about 30 mm. (fig. 83) and migrates 

 to the edge of the fin along the ninth spine and 

 the tips of the soft-rays by about 40 to 50 mm.

 membranes are pigmented, and the pigment spots 

 on the anal spines and their membranes disappear 

 above 35 mm. The pelvic is unpigmented above 

 20 mm. The pectoral spot develops midway along 

 the lower rays of the fin at about 120 mm. and 

 140 mm. Pigmentation of the caudal rays de- 

 velops at about 30 mm. (fig. 83).
