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); barbouri: In honor of American herpetologist Thomas Barbour (1884‒1946), later director of the Harvard Museum of Comparative Zoology, “through whose enthusiastic interest the opportunity of description was provided”. (See ETYFish).
