difficult to see than birds in uncalm seas, they may have been even more abun- dant than observations suggested. As no method of weighting which allows for the state of the sea has been devised, it is unreasonable to calculate comparative densities. Thus suffice it to say that there were many mammals seen, and proba- bly more were unnoticed. A total of forty-one bathythermograph casts was made over the grid track at four hour intervals. No analysis of these has yet been made. FLOCKING As on previous cruises, very little flocking was noticed in the grid except for Red Phalaropes and storm petrels. Flocking of these two species will be discussed in the grid species accounts. GRID SPECIES ACCOUNTS Black-footed Albatross (Diomedea nigripes) 54 + 1 nocturnal Overall grid density was identical to that found on the last survey, and a north to south density decline was again observed. But east-west distribution was noticeably different, there being four times as great a density in the east than in the west. On previous surveys east-west distribution has been virtually even. During this survey an effort was made to make note of any birds which had a white rump (indicative of adult plumage), but only one was seen. This would suggest that few, if any, of the 1967 Hawaiian nesting population have yet returned to this area. Fulmar (Fulmarus glacialis) 4 The low numbers indicate that the grid winter population has migrated north. It is to be expected that a few stragglers will remain behind. All four sightings were of dark phase birds.
