(syn. Cacatua Ϯ Sulphur-crested Cockatoo C. galeritus) Gr. ευ eu fine; genus Cacatua Vieillot, 1817, cockatoo; "Accepting Froriep's selection, all the names cited, Kakatoë, Cacatoës, Plyctolophus, Cacatua, Plissolophus and Camptolophus are based on a group separable from the Australian galerita, and which would be nameless were Lophochroa (proposed for leadbeateri) rejected. I have given the preceding long account as it seems necessary to have the facts on record, and I now introduce Eucacatua with Psittacus galeritus Latham, as type, so that definite results may be soon achieved. My name will become a synonym if my conclusions be accepted, but will come into use if they are rejected." (Mathews 1917) .
