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).
Eponymy: John Frederick Whitlie Quekett (1849–1913) was born in London, but emigrated to Natal (1871) and was appointed to organise the collection of the Natal Society (1886). [...] (Ref. 128868), visit book page.
