Etymology: Scylliogaleus: Etymology not explained, presumably a combination of Scyllium and galeus, i.e., a “galeid” shark with “nostrils as in Scyllium” (=Scyliorhinus, Scyliorhinidae). (See ETYFish); quecketti: In honor of London-born conchologist John Frederick Whitlie Quekett (1849-1913), Curator, Durban Museum (South Africa), who provided holotype [Boulenger consistently misspelled Quekett’s name as “Queckett”]. (See ETYFish).
