Liparidae (Snailfishes)
Etymology: Psednos: Greek, psednos, -e, -on = rare (Ref. 45335); struthersi: Named for Carl Struthers (National Museum of New Zealand, Te Papa Tongarewa), without whose help this and an earlier monograph on Ross Sea liparids would have been much more difficult to accomplish.
Eponymy: Carl D Struthers is a New Zealand ichthyological researcher who is (2005–present) Research & Technical Officer: Fishes, at the National Museum of New Zealand Te Papa Tongerewa. [...] (Ref. 128868), visit book page.
