Brief 230 May, 17, 1951 Santa Clara Co., Calif. Today Bill Woodin and I collected along Mission Ridge, east of Milpitas.

Seven of the skunks were found under rocks and boards; the other two were dug out of a fallen oak log. 4.3 mi E and 2.6 mi N of Milpitas there is a swiftly flowing stream which is up to 5' wide in spots. Much searching along the stream disclosed no frogs. The streamside plants (buckeye, Ulmus Umbellularia, live oak) are not particularly significant. There are no extensive willow thickets such as might be present if the stream were permanent. About 40' from the stream I heard a Delogonus run into a hole beneath a root protruding from a bank.
