Littlejohn's capture of a Bobolink at Redwood City is not the first record for California. On Oct. t4, ?896, I shot a female Bobolink near Monterey. This capture has been re- ported at different times, but so far as I am aware, has not yet appeared in print. On New ear's Day, x894, I took at Santa Cruz a male White-throated Sparrow and later saw another. This was the fifth record for the state. four others having been previously reported (Merriam). These with the four reported by Mr. Mc- Gregor gives a total of nine White-throated Sparrows for California.--GEo. F. BRENINGER, Phoenix, Arizona.
