Etymology: Patagonotothen: Composed from Patagonia, the Argentinian province + Greek,noton = back + Greek, adverbial particle, then, that denotes distance or removal (Ref. 45335).
Eponymy: Allan George Ramsay (1878–1903) was chief engineer of the Scotia, during the Scottish National Antarctic Expedition (1902–1904), and became the only person to die during that expedition. [...] (Ref. 128868), visit book page.
