spp., Scomberomorus spp., Acanthocybium solanderi 

 and Sarda sarda (Scombridae), Trichiurus lepturus 

 (Trichiuridae), and Makaira nigricans (Istiophor- 

 idae). We examined numerous juvenile and adult 

 Trichiuridae; our findings are incorporated here. In 



table 161 of Collette et al. (1984), observations from 

 the gempylid Diplospinus multistriatus were er- 

 roneously listed under Trichiuridae. In this paper 

 we have revised and corrected that table and incor- 

 porated all our new findings (Tables 1, 2).

1 Data from Fritzsche and Johnson (1980) and G. D. Johnson (text footnote). 

 2 Ruvettus, Thyrsitops and Tongaichthys have one predorsal bone. 



3 Rexea and Thyrsites (Leionura) have two spines, Nealotus ontogenetically has three spines but second spine fuses to basipterygium during devel- 

 opment. 

 4 Two of these spines are extreme vestiges.
