(Large file 74MB; may require a long download time. It is part of a big bundle of publications entitled, "Contributions to Arachnid Systematics in Honor of Willis J. Gertsch." The Ctenidae paper starts on page 157.)
If you use this bundle of papers frequently (I know I do), it's best to just keep it saved to your computer so you can access it whenever you want. The download time is seriously long even with high speed internet.
