Etymology: Leptonotus: Greek, leptos = thin + greek, noton = back (Ref. 45335).
Eponymy: The brief description gives no etymology. However, Waite wrote on the scientific results of the New Zealand Government Trawling Expedition (1907) undertaken by the ship ‘Nora Niven’, so we believe this to be a reference to that vessel. (Ref. 128868), visit book page.
