From Stebbing, 1906, page 4: Long before J. C. Fabricius' establishment of the Genus Gammarus, Amphipoda were described under the generic designations of Cancer, Oniscus, Astacus and Squilla. P. A. Latreille (1802, Hist. Crust. Ins., v. 3 p. 38) was the first who united all species known to him of Amphipoda (as at present understood) in one group, the family of Gammarinae, to the exclusion of all other species; later (1816, in: Nouv. Dict., ed. 2 V. 1 p. 467) he devised for the group the name Amphipoda, separating, however, the genera Cyamus and Caprella as Laemodipoda. The limits of our order, generally accepted today, were settled by Kroyer (1843, in: Naturh. Tidsskr., ü. 4 p. 490) and J. D. Dana (1852, in: Amer. J. Sei., ser. 2 v.l4 p. 297); from the latter author is derived also the division of the Amphipoda into the 3 tribes of Gammaridea, Hyperiidea and Caprellidea.
