Diagnosis A member of the Caranx hippos com- 

 plex with the following combination of characters: 

 segmented dorsal-fin rays 21-23 (exceptionally 24); 

 segmented anal-fin rays 17-19, usually 18; posttem- 

 poral bones hyperossified in specimens larger than 

 20 cm FL (Fig. 5); cleithrum, first pterygiophore of 

 dorsal and anal fins, and neural spines of verte- 

 brae relatively slender and never hyperossified; in 

 specimens >20 cm FL, heights of longest dorsal- and 

 anal-fin rays both 0.7-1.3 in head length; in adults, 

 anal-fin lobe white anteriorly and remainder of fin 

 gray to brown. 



Description Total range of values given first, fol- 

 lowed by values for holotype in parentheses: dorsal- 

 fin rays VIII-I, 21-24 (22); anal-fin rays II-I, 17-19 

 (18); pectoral-fin rays 18-21 (21); vertebrae 10 pre- 

 caudal -i- 14 caudal; curved lateral-line scales 50-73 

 (69); straight lateral-line scales 0-16 (4); straight 

 lateral-line scutes 24-41 (35); total scales -i- scutes 

 in straight lateral line 32-47 (39); developed gill 

 rakers 2-7 (3) upper, 14-17 (14) lower, 16-24 (17) 

 total; rudimentary gill rakers 0-4 (4) upper, 0-3 

 (3) lower, 4-8 (7) total; rudimentary -i- developed 

 gill rakers 20-25 (24) total. 



Posttemporal bones distinctly hyperossified in speci- 

 mens larger than 20 cm FL (Fig. 5); cleithrum, pelvic 

 bone, first pterygiophore of dorsal and anal fins, and 

 vertebral neural spines not hyperossified, the latter
