De Benedicti 1964 184 1 March on board "Golden Bear", Galapagos to Guayaquil, Ecuador appeared off the bow and 4 others to the starboard side, all together. They came high out of the water, showing the square snout & low dorsal fin of the Sperm whale. 2 or 3 appeared to be about 50 feet long and the others were not much smaller. At this time we had a man-overboard drill which slowed us up for the next hour or so. We circled back to our garbage (while the whales quickly disap- ppeared) where I was able to see 3-5 Oceanod- droma tethys and 10 2 large black petrels. Try to bare the slow wing beat of Black Petrel and do not appear very long tailed; I suspect they are hoonemania. Quit at 1:40. We toot the boat 2 to 3 P.M by crossing a tuna zone line, and I did not get out until about 10 to 4. There were 2 O. tethys and about 10 Black Petrels following the boat. Watched from the bow then of us. 4 to 4:30 I saw a Black Petrel and- Oceanodroma following one of the clicks paral- ellet to the "Bean" at binocular range, Between 4:30 and 5 within a 2 minute period (the kids one at a time) I saw 1 Heach's Petrel and 2 Co. tethys. The scamp marking were quite different Heach's anterior Tethys
