Résumé :	The occurrence of 'all-dark' Oceanodroma storm-petrels in the Atlantic and neighbouring seas is examined. The principal findings are that: the occurrence of Leach's Storm-petrel O. leucorhoa with an entirely dark rump has yet to be proven; a 'small, all-dark' storm-petrel is almost certainly a Swinhoe's Storm-petrel O. monorhis; the sole 'large, all-dark' storm-petrel record is a Matsudaira's Storm-petrel O. matsudairae; and, with the exception of freak vagrancy events, Least O. microsoma, Ashy O. homochroa, the two Pacific forms of Leach's with dark-rumped variants O.I. chapmani and O.I. socorroensis, Markham's O. markhami, Black O. melania and Tristram's Stormpetrels O. tristrami are extremely unlikely to occur in the Atlantic. A selection of photographs of North Atlantic Swinhoe's Storm-petrels is presented.
