226 LARVAL TELEOSTS 



The later larva (Fig. 308) is characterized by the appear- 

 ance of abundant pigment masses (not shown in the 

 figure) in all regions of the trunk; branchiostegal rays, 

 GR, and traces of pelvic fins are noted ; the caudal fin 

 has become separated from the dorsal and anal elements. 

 And finally, in the stage of Fig. 309, the fish, although 

 still of very small size, has acquired almost perfectly its 

 mature features ; the outward differences are only those 

 of pigmentation and fin proportions.
