What kind of spider has a big white abdomen with orange legs?

What kind of spider has a white abdomen, and stripped legs?

• I was walking from my car into my house and this spider seemed to fall from no where (most likely from carport) but it really scared the sh** out of me. It's body was about the size of a penny and it had long stripped legs. I smashed it pretty well with a shovel because it was too big to move it to the garden. I searched online but I couldn't find it. Any help would be nice! Thank you!

• Answer:

  These two spider species look rather frightening, but the bodies of two of them fit comfortably on a penny > http://bugguide.net/node/view/374059 http://bugguide.net/node/view/268819 A 9 mm one > http://habitatnews.nus.edu.sg/guidebooks/spiders/text/Cyrtophora_beccarii.htm Might be better you take a look > http://bugguide.net/index.php?q=search&keys=spider+white+abdomen&search=Search
