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); mitsukurii: In honor of zoologist Kakichi Mitsukuri (1857‒1909), Imperial University of Tokyo (Japan), who provided the specimens that Bashford Dean used in a concurrent description (with same name) published a few months later (See ETYFish).
Eponymy: Dr Kakichi Mitsukuri (1857–1909) was a Japanese zoologist who first went to the USA (1873) and achieved doctorates from Yale (1879) and from Johns Hopkins University (1883). [...] (Ref. 128868), visit book page.
