Etymology: Normichthys: Because of John Roxburgh Norman, British ichthyiologist 1898-1944 (Ref. 45335).
Eponymy: John Roxborough Norman (1898–1944) was an English ichthyologist who started his working life as a bank clerk. [...] The Yahgan, also called Yaghan or Yagán, are an indigenous people of Tierra del Fuego who, according to the author, “…practiced shellfish conservation and avoided exhausting their food supply.” (Ref. 128868), visit book page.
