336. this evening there was a large flock of Larus californicus and Larus glauciscens on the water. I saw two or three Phalacrocorax auritus south- bound. While the ferry boat was in the slip on the San Francisco side this evening gulls were very common. Two or three Larus glauciscens alighted on the forward deck. Along with it was a Larus glaucus. It was very nearly pure white, the only ex- ception being some brown spots on the wings and back. I am very certain of its identity. After it left the deck I saw it once again as it flew out from behind an incoming steamer. March 15, 1909. Alameda to San Francisco, California. Both this morning and evening quite a few ducks (Scamps and Scoters) were seen along the mole. On the Bay this evening Larus glaucus and Larus Californicus were common, several of the former sitting on the lower deck of the steamer while in the slip on the San Francisco side. I saw a Phalacrocorax auritus going south and several seven Scamp ducks going north. Mar. 16, 1909. Alameda to San Francisco, Cal,
