Yet another spider ID request

I have been unable to identify what I'm sure is a common spider. A photo is
available at http://hargrove.org/spiders/image008.htm. When I touched the
spider, it feigned death, as shown in
http://hargrove.org/spiders/image009.htm. To see all the photos, go to
http://hargrove.org/spiders/index.htm.

Any help would be appreciated. I am already indebted to this newsgroup for
identifying Neoscoma oaxacaensis for me.
