Etymology: Archosargus: Greek, archo = anus + Latin , sargus = sea bream (Ref. 45335).
Eponymy: Louis François de Pourtalès (1824–1880) was a marine biologist born in Switzerland who spent most of his career in the USA. He presented his extensive collections to the Harvard Museum. No etymology is given, but we presume this to be the person intended. (Ref. 128868), visit book page.
