Bathylagidae (Deep-sea smelts)
Etymology: Bathylagoides: Greek, bathys = deep + Greek, lagoides = similar to a hare (Ref. 45335).
Eponymy: Lars H Weseth (1895–1982) worked for the California Department of Fish and Game (1930– 1960) as captain of a number of research vessels including ‘Albacore’, from which the holotype was collected. [...] (Ref. 128868), visit book page.
