fish about 100 mm. SL have 7 to 12 bars, and tlie 

 few specimens between 150 and "200 mm. SL have 

 12 to 14 bars. The largest western Atlantic speci- 

 men, 216 mm. SL, has 22 bars. Throughout the 

 size range examined here the bars are distinct on 

 some fish but indistinct on others and arranged in 

 pairs on some specimens but not on others. 



FIN RAYS 



The numbei-s of fin rays for western and eastern 

 Atlantic specimens with undamaged fins are 



witliin the adult complements. I prepared tables 

 of mimbers of fin rays for western Atlantic speci- 

 mens only. The fins of a number of eastern Atlantic 

 specimens were damaged, and too few counts are 

 available to make usefid tables. The nuniljers of 

 fin rays for eastern Atlantic specimens are within 

 the ranges for western Atlantic specimens, except 

 for a few differences which are mentioned in the 

 discussions. 



The total number of dorsal fin rays ranges from 

 ■47 to 56 (mean, 51.6) for 142 western Atlantic
