larger and covering more of the fin lobes, the 

 blotches are distinct on a series of specimens 101 to 

 119 mm. SL. On a 190-mm. SL sailfish, pigment 

 spreading posteriorly from the base of the fin joins 

 that spreading anteriorly on the lobes and covers 

 the fin except for the distal half of the middle se\-en 

 caudal rays and ray membrane, which remain clear. 

 On the largest specimens, 216 to 238 mm. SL, the 

 clear area of the middle part of the caudal fin is 



reduced to the distal third of the middle six caudal 

 rays and ray membrane, the lobes of the caudal fin 

 ai-e dusky, and the tissue covering the bases of the 

 rays is densely pigmented. 



Body Bars 



Pigment on the sides of the body is concentrated 

 in five to seven bars on fish of about 30 mm. SL. 

 Bars are not discernible on smaller specimens. Sail-
