Etymology: Hydrolagus: hydro-, combining form of hydor (Gr.), water; lagos (Gr.), hare, i.e., “water rabbit,” probably referring to three pairs of tooth plates, which tend to protrude from the mouth like a rabbit’s incisors (See ETYFish); deani: In honor of American ichthyologist Bashford Dean (1867‒1928), for his “able studies” of chimaeras (See ETYFish).
Eponymy: Dr Bashford Dean (1857–1928) was an American zoologist, ichthyologist and acknowledged expert on mediaeval armour. [...] (Ref. 128868), visit book page.
