But see Gill 1901:735 [ref. 9562] who indicates that Cloquet used two sources but essentially made his generic description from an account by Home 1815 [species later named Homea banksii Fleming, 1822], and that Cloquet's citation of dombey [as dombeii] was a misidentification. Action by the ICZN is desirable; possibly to designate Homea banksii Fleming, 1822 as the type species to continue current usage. Also, although Cloquet gives the author of his Eptatretus as Duméril, Cloquet is the first to Latinize the generic name and make it availabale, and Cloquet is author of Eptatretus.
