First dorsal-fin pterygiophore in lateral view (anterior of pterygiophore on left). Outlines 

 were traced from radiographs plotted against fork length of Pacific crevalle jack (Caranx 

 caninus) (pterygiophores numbers 1-36), crevalle jack (C. hippos) (37-83, western Atlan- 

 tic, 84-87 eastern Atlantic, in black), and longfin crevalle jack (C fischeri) (88-106). 

 Numbers correspond to those given in Appendix 1 with associated catalog numbers, 

 specimen sizes and localities. 



crysos, C. latus, and C. lugubris) commonly are found 

 at insular localities, including Ascension Island on the 

 mid-Atlantic ridge.
