Feb 29 on board "Golden Beam" Galapagos to Guayaquil, Ecuador bow but only 1 Masked Booby, floating or what appeared to be a whale. logged aboard, was seen to 4 P.M. Between 4: and 4:30 [illegible] 10-15 small (6-8 ft.) porpoise came quite close to the ship. They were much struck. fin 2x higher than dirty white, dark olive wide. Some dark about the line dark line separating two colors face and fins, apparently a beak but hard to see. They were leaping completely out of the water and falling down on their sides, making a high splash and audible over the boat twice at 75 feet. One came very close to the ship but did not play in the bow wake, and after a few minutes left the ship. May have been the same small porpoise I saw this A.M. No birds with this group; a petrel was with each of the groups seen in the A.M. and a Booby was with the large oliv porpoise. Saw another Masked Booby sitting on the ocean between 4:30 and 5, when I quit. Went to the stern to find 10+ small Ocean-odema (seaflys) following the boat and at least 2 larger petrels with them. One had a white rump and was only a little larger, with not much different wing beat [a little slower] and I took this to be ceacio. "The other" was all black and 1 1/2 times as large as the ceacio, with a much slower jerkier (pause between strokes longer) wing.
