Google Webmaster tools showing URLs that I can't find

[greggbanse]

Somehow Googlebot has found a handful of URIs that look like this:

http://www.thesitedomain.com//imagecata ... e/list/20/

The generate 404 errors when you go to them.

I can't find these and am wondering how Google found them. I'm not sure if this is part of ShopSite but since the rest of the site is static (hand built by me so I know every URL I included) I don't know where else to look. Does anyone recognize this?

Nothing in the url looks like anything generated by ShopSite.

Thanks Jim,
I know but I didn't get these errors until I made ShopSite live. Could it be something that Pair has installed that I'm not aware of?
