We collected a carcass of medium-sized wholly dark shearwater at Minami-Koshien Beach of Osaka Bay (34°42′30″N, 135°21′30″E) on 21 September 1989. The billand the leg-color of the carcass suggested that it was the dark morph of the Wedge-tailed Shearwater Puffinus pacificus. All the measurement values of the carcass on wing, tail, bill and tarsus fell within the ranges of P. pacificus, but not of any other dark shearwater species. We concluded that the shearwater of Minami-Koshien was the dark morph of P. pacificus which is distributed in the tropical and southern waters south of 10°N. We speculated that the typhoon which passed by Osaka Bay on 19 September 1989 carried the shearwater to Japan. This is the second record of the dark morph of P. pacdficus from Japan. The skin is stored in Museum of Nature and Human Activities, Hyogo.
