5 Newell's Shearwater Puffinus puffinus newelli Two were observed on 11 April within 50 miles of Oahu Dark-rumped Petrel Pterodroma phaeopygia Four were observed during the first five days of the cruise. The bird of 15 April was at 28°15'N 148°45'W, a distance of 600 miles from its nearest breeding colony on Maui. This record probably constitutes the northernmost sighting of this species. Bonin Island Petrel Pterodroma hypoleuca Three were observed on 15 April at a distance of 900 miles from their nearest breeding colony. Cookilaria sp. Small, light grey backed petrels of the cookilaria group were observed on 18 and 20 April. The fairly narrow, but distinct, dark underwing edges indicated that the birds probably were not those with which the author has some familiarity, P. h. hypoleuca, P. h. migripennis or P. leucoptera masafuerae. Bulwer's Petrel Bulweria bulwerii Eleven were seen within 50 miles of Oahu. Leach's Storm Petrel Oceanodroma leucorhoa April 11 12 13 14 15 16 17 18 19 20 21 22 23 0 1 15 2 3 3 1 0 0 5 2 0 3 Observed most days of the cruise. Those observed between 12 and 17 April appeared to be migrating north, while those seen between 20 and 23 April were flying non-directionally or were sitting. The former group may be the Aleutian population, the latter the west coast population.
