Note. Caranx ascensionis Cuvier is the oldest available name for this species but C. Iugubris has had much greater usage in both fishery and taxonomic literature. In the interest of nomenclatural uniformity and stability, the junior name is retained for this species pending a petition to the International Commission of Zoological Nomenclature.
