Nettastomatidae (Duckbill eels)
Etymology: Facciolella: Latin, diminutive of falx, falcis = sickle (Ref. 45335); gilbertii: gilberti for Charles H. Gilberti, 1859-1928, a distinguished American ichthyologist (Ref. 4525).
Eponymy: Dr Luigi Facciolà (1851–1943) was an Italian physician and ichthyologist who was the first to recognise and describe the Witch-Eel genus (1911) but in doing so used a preoccupied name (Nettastomella). [...] Dr Charles Henry Gilbert (1859–1928) was an ichthyologist and fishery biologist, whose main area of study was Pacific salmon. [...] (Ref. 128868), visit book page.
