This evening the only species of gull noted was Larus californicus, but in an immense variety of plumages with the exception of the white-headed adult. The most were seen at or over the junction of the two currents south of Goat Island; Near here also were observed about a dozen terns (Sterna forsteri ?) all flying, not particularly close together, and some calling. Among them was a jaeger, apparently Ster- corarius pomarinus in adult plumage. September 21, 1907. Alameda to San Francisco, cal. Conditions: - Stormoon; nowind; fairly clear.

Alameda to and from San Francisco, cal. Conditions: - Overcast in the morning; moderate temper- atu re; westerly wind.
