Etymology: Apristurus: a-, Latin privative, i.e., without; pristis, from pristes (Gr.), sawyer (but here meaning saw); oura (Gr.), tail, referring to absence of saw-toothed crest of enlarged dermal denticles along upper edge of caudal fin as found in the closely related Pristiurus (=Galeus). (See ETYFish); laurussonii: In honor of Saemundsson’s friend Gísli Lárusson (1865-1935), goldsmith, watchmaker, farmer and nature enthusiast, for his “long and invaluable support of the study of Icelandic fishes, and for carefully encouraging the skillful fishermen of Vestmannaeyjar Island [near type locality]” (translation). (See ETYFish).
