_Remarks._--Osbert Salvin received two specimens of this shearwater from H. J. Snow, who got them at the Krusenstern Islands in 1883. In describing them, Salvin (1888:353) comments that the locality is seemingly in the Marshall Islands at approximately 10°17´ N. and 190° W. This locality was confusing to Seebohm (1891:191) who thought it was between the Hawaiians and the Marshalls, while Hartert (1926:352) decided it was really Krusenstern Rocks in the Hawaiian Group. To clear the matter up, Fisher (1946:587-588) writes that Salvin was correct and suggests that the name of the island should be the better established one, Ailuk, rather than the little used one, Krusenstern. _P. p. cuneatus_ resembles _P. p. chlororhynchus_ but is whiter on the underparts, especially the breast. These two subspecies are inseparable according to the twenty-fourth supplement to the American Ornithologists' Union Check-list of North American Birds (Auk, vol. 66, 1949:281). =Puffinus tenuirostris= (Temminck) Short-tailed Shearwater _Procellaria tenuirostris_ Temminck, Pl.

Ranges north to the Bering Sea. In Micronesia: Mariana Islands--Guam?; Marshall Islands--Kinajon. _Character._--A rather large shearwater with short, rounded tail; upper parts sooty brown; underparts paler and more grayish than back; throat may be occasionally whitish; bill lead-gray; feet grayish, browner on outer side. _Remarks._--On migration this shearwater probably reaches most parts of Micronesia. It has been recently recorded by the Japanese at Kinajon in the Marshall Islands. Bryan (1936:15) includes this species as a "chance arrival" in his list of the birds of Guam. =Puffinus nativitatis= Streets Christmas Shearwater _Puffinus (Nectris) nativitatis_ Streets, Bull. U. S.
