"To sum up the writer's conclusions from the material examined: Vomer and Selene are both derivatives of Caranx through Hynnis, and all four genera separable. Three valid forms of Vomer exist, as differentiated by Jordan and Evermann on variation in depth and fin rays: dorsalis, setapinnis, and cubensis (= gabonensis J. and E., not of Guich.). There is great age variation in depth and considerable individual variation in fin rays. The three forms are close and probably overlap in characters, rather than in ranges to the extent supposed by earlier authors; though, as their migrations, aided by ocean currents, are considerable, this is not certain. Dorsalis is the west African form; setapinnis, American, both Atlantic and Pacific; cubensis West Indian (Cuba). The three should stand as subspecies of setapinnis. Pacific V. s. setapinnis differs slightly but not recognizably from that of the Atlantic"--P. 676.
